I believe that myself..evil people can still be brilliant, and can in
retrospect, teach us a lot about ourselves as a human race.

Were all animals, capable of horrible or fantastic things.  What we do with
that knowledge and power is the real problem.


What genre of quoteable will we be debating next?  MANY people worldwide
hate/despise many things.  If we begin here, where does it end?

Will we be discussing a kernel level "hitler" filter next?


C'mon, I believe that most reasonable people can separate the actions of
someone from their words from a historically relevant point of view.

The difficulty for my moving the last of my Linux boxes, is...iscsi support.

God how I wish I could map luns, boot from luns, and share lun love with my
other freebsd boxes.


Im starting on another venture, that I -want- on FreeBSD, but likely will
not be able to, because I cant use iscsi on it.  (And wont on Fbsd until its
been out for a while and proven stable).

But other than that, my move was painless, I -hate- installing RH.

Re: Installing freeBSD on an Intel RAID5 partition

[Jeff Mohler]

SATA drives just aint built with the same resiliency as SCSI, hence
the massive difference in cost.


So..as an example, the Hitachi 500G 7K500 drive has a non recoverable
bitrate of 1 in 10^14th.  The 10K300 FCAL (basically scsi) drive is 1
in 10^16th.  Those two zeros mean a _lot_.


I removed a lot of my own math here, knowing that Ive read this
somewhere before..huzzah for google!

http://blogs.netapp.com/dave/2006/03/expect_double_d.html?no_prefetch=1

Im used to working with much larger drives, in very large RGs..so Im
correctable, youre not going to play with the devil TOO much in a home
for small business system, just not enough drives.

But now you can find 1TB drives, and 7 of those in a raid wont be hard
to find pretty soon.

Eventually..you will hit a non recoverable bit error during a
reconstruction, and you wont have parity to go to, to recover it.
Unless youre using a dual parity layout of some type.

Drives are also more common to fail when put into use from being
spares, because theyve never been exercised over a long period of
time..ya never know.

The quality of the firmware that operates consumer SATA isnt near the
level of quality that server drives are either, which can create ghost
errors that dont truly exist, but to the OS are in fact errors which
can shave off a few zeros as well.

Re: Installing freeBSD on an Intel RAID5 partition

[Jeff Mohler]

Did you know that most "oh my god" RAID failures happen during the
reconstruction of a failed drive?

.Especially on SATA as the non-recoverable-bit-error math is so much
easier to run into.

I think..that on a 500G drive, there are enough bits to read/write
that mathematically you could run into a double-drive failure every
time you have to recover.  Although, statistically it wouldnt happen
every time.

No raid solves any backup problem.

Re: Best SCSI or SAS RAID for a NAS?

[Jeff Mohler]

Tell us what your workload IS..that will help a lot.

Its not necessarily MB/sec, but disk IO's per second.


Such as..if you have 5 servers with applications creating 100 IOPS on the
local drive, then you need a RAID array capable of at least 500 IOPS at
under 20ms to remain happy with it.

You can expect up to 180 IOPS under 20ms on 15k drives, and 100-120 on 10k
drives (or thereabouts) to also remain under 20ms per random IO.

Notably, the overhead of the raid layout will factor into this as well.


Tell us what your load will be, then you can get reasonable configuration
guidelines.

Re: Unbelievably bad RAID-1 performance

[Jeff Mohler]

The EDGE is faster byte wise, not the center.

The distance between traditional or perpendicular sectors remains the same,
just more of them around the drive at a given distance from the center, than
at the center.  So..because RPM remains the same at all distances from the
center, you will read more sectors per second at the edge, than center.

Although..that wont make a 100x difference in speed..I wouldnt think.

Re: 10Mbps versus 100Mbps Cable Modems

Yup..and it goes back to my original point.

If it saves $5/box times 100,000 units and they charge you the same for the
box rental/purchase, its a good business decision.

So 10Mbps = 10240kbps  and 1024kbps = 1Mbps
Then a 10Mbps cable modem can feed their network faster
than even the fastest service plan they offer.

Do I have correct understanding now?

They probably did it because the number of subscribers
has increased to the point that they need to start
limiting bandwidth to ensure that everyone gets their
fair share. They probably allowed subscribers to
exceed their allotted max bandwidth while the number
of subscribers was sufficiently low that they did not
have to worry about it. Now that they have a lot of
subscribers, they have to worry about it.

Do you have more than 10Mbit/sec of cable internet bandwidth available?

I dont see it as a problem if you dont, but if you have 20Mbit/sec of
internet, then ya..

If it saves then $5 a unit, for 10,000 units, no harm.

Tar is expensive time-wise anyhow after a while if you use compression.

Also, rsync does diffs on files, which can become expensive in terms of
time.

Re: Video fileserver - Need some input

[Jeff Mohler]

The _main_ think I can think of, is windows in a SINGLE threaded movement of
data via CIFS, is gonna limit you to about 17MB/sec.

Andreas..have you tested this via CIFS/Redirector and been able to sustain
the performance that you need before going with Samba (another performance
layer issue)

My apologies, I totally glazed over that bit.

Samba does have some performance issues out of the box (see Solon Luigi
Lutz's thread from 04-10, similar situation but a little bit more later
in the game).  I believe there are a few tuning options for
Samba<->FreeBSD that might be appropriate, esp. wrt. multi-threading
CIFS.  Google seems to show a lot of hits for that.

Sorry again for missing the info you provided.  I hope this helps.

Depending on the resolution and frame rate of your video, GigE is
nowhere near fast enough a pipe for live video manipulation.  This is

I know with Windows Storage Server, if a user modifies the file, it will
then create the user their own copy of the file. This happens
automatically. Exchange Server is another example of this type of
storage. When someone sends an attachment to several people, the server
saved one copy of the file. I am currently managing 7TB worth of data
with roughly 1 to 2TB of duplicate files. This gets fairly expensive
with a fiber channel san backend. I know it can be done in the windows
world automatically, just wondered if it could be done automatically in
the Unix world also.

Re: Single Instance Service

Serving home directories, you end up with tons.

One marketting dude creates a 10Mb PPT slide, sends it to 10 people that
forward it to 2 more each...

Next thing you know you have dozens of copies of thousands of the same
documents sitting in deep storage home directories, taking up space.

In backups, SIS is the killer feature, in spinning storage..its worth 200%
the cost of the storage you save.

Most of us..would never need it..but for those that do..do.

All messages are already tagged with a List-ID

e.g.

List-Id: User questions 

Can gmail not filter on that?

Visual tagging of subject lines is a poor solution.  Either you tag at
the front

   "[fbsd-questions]  Really long subject line that gets truncated even
earlier thanks to the tag"

or at the end

  "Really long subject line where the tag disappears in a haze of ...
[fbsd-questions]"

Neither of which is satisfactory, and for most people with sensible
email environments that can filter of Header lines, an unnecessary
inconvenience.

Not to mention the question of how on earth you co-ordinate unique tags
across mailing lists.  Since the List-ID isn't constrained by length it
can contain the email address of the list, which is already unique.

If you can't filter on the List-ID then filter on To and Cc lines which
contain [EMAIL PROTECTED] or [EMAIL PROTECTED]  Not as
good, but it would do.

Re: Terabyte harddisks, GELI, AMD64, Samba and Zen...

[Jeff Mohler]

Was your 17mb/sec a drag & drop from a windows client?

17Mb/sec is about right, as Windows deals with that as a single threaded I/O
operation.

You can stuff a GigE pipe from a windows machine to a netapp or some other
solid CIFS server if you can fire up multiple threads to copy with.

So..dont feel bad, thats just the cap of a single threaded copy from
windows.

As I started to fill up the volume, I experienced random crashes -
always while doing high-speed transfers over gigabit ethernet between
this and another server. Mostly 1-2 per day - might be a hardware
problem or not.

Due to the slow CPU and software encryption, the maximum speed is somewhat
limited (raw speed is somewhat around 600 MB/s):

But I have not been able to get more than 17 MB/s when using Samba to
transfer data - FTP maxes out around 27 MB/s. I also tried that on
i386 32-bit and found it to be 8 MB/s and 17 MB/s - not good, but
nothing to worry.

What made me feel really uncomfortable was the fact, that just some
minutes ago some 3000 1GB files suddenly disappeared while working
in a directory. They where gone, but the filesystem did not report
some additional 3TB to be free and after unmounting and remounting the
filesystem the files were back where the belonged...

This just happened some minutes later again, now with only 2500 files
dis- and -reappearing again.

Questions until now:

1. 10TB as a single volume, too big for good? (fsck time: 30 min with
softupdates)
2. GELI unstable on big disks and/or AMD64?
3. Why is Samba so slow?
4. Does the crypto-framwork gain speed advantages from dual-core CPUs?
5. Will the GPT-stuff change over the next releases in a way I need to
do DUMP/RESTORE?

Thanks for your patience...

Indeed,

You may need to run ldconfig -R (or ldconfig -m /usr/X11R6/lib

Alternatively, you may have an older version of open-motif,

Most of the time the way peer-to-peer filesharing is used, the point is to
hide the sources of the streams, in order to distribute illicit material.

What your talking about only works if you have a large group of FreeBSD
volunteers
that are willing to run the torrent servers.  Let's assume that only 0.01%
of any
population group would step up to the plate to offer a torrent
server.  Well
I can see a Linux torrent network working because Linux has an order of
magnitude
greater number of users than FreeBSD.  But I think you would find it
impossible
to recruit something like 1000 FreeBSD users to step up to the plate and
offer a torrent server.  The population numbers just aren't there.  Worse,
the
initial people that offer the server are going to get the brunt of the
load
and
you can't give them any guarentee that your going to be able to recruit
future
torrent servers to lessen the work on them.

Like out-of-control-broadcating on an Ethernet nework, sometimes in
networking
things just coalesce out of nowhere when the network gets large enough.  I
don't
think we have enough FreeBSD users in the population to depend on things
like
this just appearing by themselves.

FreeBSD came to the "grow big or grow well" crossroads many years ago and
took the "grow well" path.  Linux took the "grow big" path.  It is very
much
like
what happened to MacOS and Windows.  One grew big, the other grew well.
Today, though, neither can really change.  FreeBSD can no more displace
Linux
in terms of numbers and in terms of newbies using it, than Linux could
displace
FreeBSD in terms of being able to be usable for commercial products, or
displace
FreeBSD in terms of being able to collect the absolute best developers in
the
industry.  I think the Open Source world is much better off for this
happening since
it gives more different choices for the consumers, but by the same coin
your
going to be frustrated if you try to make FreeBSD look, walk and talk just
like
Linux.

Re: Could we get the FreeBSD torrent servers back?

It would be a facinating experiment if a lrge group of Fbsd users at
1000s of hosts were recruited as supporters to the Fbsd Organization..to
host some subset of critical files.

It would be super neato if you could configure what you wished to donate via
a tool that would populate your box with specific data.

Re: RAID Performance Questions

[Jeff Mohler]

How about one large raid, and two partitions to serve each purpose?

Being so limited in HW, youre either going to take a _huge_
performance hit with only 2 disks per raid (unless Raid0), or an
availability hit with everything on one RAID set.

But..considering the costs of adding RAID to a server..take a peek
here for a high(er) perfomance RAID solution..if Fbsd had an iscsi
layer like linux has had for...5yrs or so..this would be a slam dunk
as you can still serve it as block data.

If that cant help you, it might help the next guy with only a few K's
to spend on large disks and raid controllers.

Unfortunately, I'm a bit limited in terms of equipment and
application requirements. For starters, the app specs currently call
for two arrays: one for general file-serving and databases, and the
other for backups. Due to limited hardware I'm to run both on the
same controller. Far from ideal, I know, but it's what I have.
Second, I need to keep at least one drive as a hot-spare. Thus, I
have seven drives that I somehow need to partition into two groups
and maximize performance without sacrificing reliability. Lastly, the
RAID controller does not permit more than two drives in a RAID-1 set.

Any suggestions?

Re: more than 7 partitions on a SCSI-drive

Ive never understood why we still partition drives so much..its one

issue..but..its one spindle.

If there is a fundamental reason why we still partition things like we
only have 10, 20, or 40Mb RLL. or slightly larger ESDI drives from
back in the day..im willing to learn.



On 1/21/07, Christian Baer <[EMAIL PROTECTED]> wrote:

Hi folkes!

Is there any way to do this with FreeBSD?

Background:

I have to admit, that I have never actually done or even tried this with
any OS whatsoever. I am running a two drive system with two mirrors on
it. Because I wanted a lot of room for /usr while /usr/home ist mounted
on a different partition, the second drive is filled with the two
mirror partitions, /usr and a swap partition. Everything else is mounted
on the first drive. That being: /, /temp, /var, /usr/obj and the second
swap partition. Together with the two mirrors this means seven (in
words: 7) partitions. The table looks like this:

Filesystem  SizeUsed   Avail Capacity  Mounted on
/dev/da0a   501M 72M389M16%/
devfs   1.0K1.0K  0B   100%/dev
/dev/da0d   1.9G102K1.8G 0%/tmp
/dev/da1f21G2.9G 17G15%/usr
/dev/da0h   6.8G742M5.5G12%/usr/obj
/dev/da0e   4.8G 71M4.4G 2%/var
/dev/mirror/sec1.eli9.8G7.5M9.0G 0%/usr/home
/dev/mirror/sec0.eli 34G 21M 32G 0%/usr/home/christian

What really sounds (and probably is) pathetic is that I have nearly 6
gigs of 'leftover' space on da0. Increasing the size of the mounted
partitions isn't really useful anymore (apart from reducing the free
space) as I for example probably won't be needing 2GB for /temp or more
than 5GB for /var - those are the sizes I have allocated now. Making /
any bigger than the current 512MB wouldn't bring any advances either.

Increasing the size of the mirrors isn't an option because that would be
schrinking /usr. Finding a new mount point wouldn't be a problem. I was
thinking something along the lines of /usr/ports. /usr/src was an idea
at first but since I want to keep that on a different physical drive
than /usr/obj, the idea doesn't seem that bright anymore.

But the
problem is that I can't allocate another partition, not that I ran out
of ideas for mount points. :-) On other machines with IDE-drives I had
one slice with partitions inside and never ran into this limitation
before. Is there any way to do something like that on SCSI-drives? We
are talking about SPARC64 here.

Chris

Re: is THIS why the 6.2 release seems stalled ?

[Jeff Mohler]

Yes, they dont solve this whatsoever.  Its a severely broken code
issue in the attr caching mechanism.

Honest..give it a shot.  Even with very very slow ATA, local builds of
the kernel or world are faster than over 1G NFS to an F6000 series
filer, and the filer will still thrash on WAFL metadata requests for
the client, cuz everytime ../.. walks somewhere the client knows
nothing and it's all sent over the wire again.  Over and over and
over.

Thats as much as I understand about it, freebsd-fs has great detail on
this "bug".

I dunno..Linux got _somewhere_ before big money came into it.

Like I said..when Fbsd 2.5 was light _years_ ahead of Linux..sometime
after that, focus was lost.

Perhaps chosing to emulate instead of innovate (work smart not hard)
didnt pay off as well as everyone hoped.

..not that nobody worked hard..just that perhaps a decision was made
to let the linux community write the new code and Fbsd community would
polish it and/or emulate it once it was complete.

I don't actually have a problem with FreeBSD and NFS. This is using about
20+ clients and 2 NetApp filers. What problem are you having, rather than
just "goes to crap"?

---
If for example you do a make buildworld or a kernel build (anything
that uses a lot of ../.. to walk the dir structure) you will find that
it is way slower than the same builds on local disk.

The basic reason is that a ../.. walk invalidates cached metadata, and
you end up with a pipe full of getattr's all of the time.  Freebsd-fs
has discussed this a bit, but no fixing is coming soon.  We use linux
to compile builds, we'd like to use Freebsd, but linux on Filers via
NFS is about 3x faster than the same builds on Fbsd to the same filer.

So you need people to work freely, without any pay, to make things work
for you, so you can complain when something isn't working like you
want it to!? So you can get real things done!?

If you have a business to manage, and just need this to work, made by

I'd like to see FreeBSD on top too, I really love and care for it but
I'm very disappointed and ambivalent with the projects current state
of affairs. I think one project that should be attempted is to get
FreeBSD running on top of a Linux kernel. This could potently solve
FreeBSD's biggest problems We could mold it (the Linux kernel)
into are own kernel while still maintaining compatibility with the
real Linux kernel tree. anyhow... it's something to think about.

Fbsd needs SAN support before it can cope with
virtualization..virtualization requires a lot of disk..spindles..and
FCP/iSCSI is a great way to drive this condensation.

I mean..when you have to read this list, and see people wonder which
end of a SAN connection owns the responsibility for fsck'ing a SAN
filesystem, I wonder how quickly I can bone up on Linux.

In ten years at Network Appliance..wanna know exactly how many FreeBSD
host installs ive seen besides Yahoo?

2.

How many -non- Linux SAN configurations?  Probly 80% of all SAN I see
and work with are Linux based.

Fbsd NFS client performance is 1/3'd that of a tuned linux box, can
you say ../..?  If you can, you know what its like to never have a
valid directory attr cache on your mounts.  (ick)  Automount...dont
even go there.

But I use Opera?? And It needs to work with youtube, without crashing
and without install headaches. 'cd /usr/ports/www/flash; make install
clean; exit;' then open browser to youtube.com and go. No library
shuffle or libmap configuring.

Yes, and they have done their part. Now it's FreeBSD's turn to
integrate the changes needed to the kernel into the kernel to make
Dom0 support work. Linux has it, Solaris has it. NetBSD has it. Mac
has it? FreeBSD does not have it. Server virtualization is the next
big thing and FreeBSD has nothing going for it in this respect... Not
even VMware or any of the other big players works with FreeBSD as a
host OS.

Re: iSCSI

[Jeff Mohler]

I never said it was, my rather poor example (I said I was new to iSCSI)
was if a remote file system crashes, who should fsck it? The server
(Target) or the client (Initiator)?

---

Clearly, the initiator.  It owns the filesystem.  Its just a big
anonymous file on the target with no relevant structure that it cares
about.

That only works if the target comes up within the 2min window that
SCSI allows for.  It won't wait forever.

Why should the client need to do an fsck?  From its point of view it
should just look like the target had the iSCSI equivalent of a bus
reset.  It should resend any queued requests and continue.

Re: Empty directory 60M in size; used to contain 1.7 million files

[Jeff Mohler]

The directory size grew to accomodate the metadata required to list
the files within it.

You cant shrink it.  You'll have to remove it and recreate it.

The one special circumstance is that the directory previously contained 1.7
million small files, that are now deleted. This is on FreeBSD 6.1 with UFS2 +
softupdates. No snapshots exist of the filesystem.

1.7 million files may be extreme, but I don't see why an empty directory would
ever consume more than one inode?

Yeah, well... that's a funny thing that tag. Got it on my

Well, if you have the D830, no, because it doesn't have HTT support. :)

As a general question, the answer is yes and no. Depends on your
application basically, as well as the operating system itself. It's
one of those questions that'll lead to long and detailed flame wars,

This is a dmesg from an Intel D830 box:

CPU: Genuine Intel(R) CPU 3.20GHz (3217.43-MHz 686-class CPU)
Origin = "GenuineIntel"  Id = 0xf47  Stepping = 7

  AMD Features=0x2010
  AMD Features2=0x1
  Cores per package: 2

I think you do have a single processor with hyperthreading (logical
CPUs) and not a dual-core model.

To get hyperthreading up and running, you need to add:

machdep.hyperthreading_allowed=1

to /etc/sysctl.conf or change it manually. Please google for the
security implications of doing this first though.

6.x is 5.x with performance bottlenecks fixed.  This applies both to
UP and SMP systems.  Therefore it's pretty surprising that you're
seeing a slowdown between 5.x and 6.x, so you should try to look into
exactly why your system seems to be running slower.  Perhaps it's just
a simple misconfiguration, or related to some other change you made at
the same time as you updated.

I think it's more that there's more than one kind of Joe Public. If you
want to present your graphs to your customers/users, or a subset to
different users, or apply the same set of graphs to a number of
different hosts, or make custom rrdtool graphs (stacks, additional graph
elements), then Cacti will let you do that. If you just want a quick &
dirty tool that's easy to configure for your handful of hosts, then MRTG
is just the job.

We use both where I work, with Cacti for the bulk-graphing and customer
facing stuff, and some MRTG where I just knocked up a quick perl script
to measure something. Cacti has quite a nice plugin system, and
importable templates from other users that you might be able to use to
save yourself some time. I find getting my own templates working in
Cacti to be a PITA too, though.

It also has some useful plugins, including a couple of my
own. The main one of those being PHP Network Weathermap
(http://wotsit.thingy.com/haj/cacti/) which will work with both MRTG and
Cacti, to produce graphical overviews of your network.

Bear in mind there are also other tools out there in the MRTG/Cacti
space: DVG, NRG, Hermes, Cricket... rrdtool.org has a list of many. Most
are geared towards folks running 100s-1000s of graphs, that I have seen,
and may not be your kind of thing, as a result.

Howie

I just bought one and I can't figure it out. It has BNC connector and

With ifconfig_xl0="DHCP" in /etc/rc.conf and BNC cable connected (with

Now, if I manually try to switch to BNC media with:

# ifconfig xl0 media 10base2/BNC

I get:

and a kernel panic (trap 12).

The BNC cable itself works with another box. More information below.
Any help appreciated.

Try using fastest_cvsup and you can see what kind of response the
servers are providing. I did a
fastest_cvsup -c us
and it showed at 1837 UTC that 1 and 3 were at the limit and cvsup6 is
probably down.

They update from the master on the hour and you need to wait 10-15
minutes for the update to finish. There isn't any magic time where they
all work but you can find one closer to the next update where you get
through almost all of the time.

NFS client attr caching question..

Can anyone answer these questions?

What size the NFS client attribute cache is?
Is it a per mount cache, or a systemwide cache?

Re: apache20 going nuts

[Jeff Mohler]

I was just there on 5.1 for the last few months..when I did a
kdump/ktrace, I saw invalid fnctl's just sucking things up.

I nailed it down to something in PHP, because I could trigger this
immediately by uploading photos to my coppermine installation, or
randomly with zencart.

Moving those services to another box but still using mysql on the
questionable server was just fine, so I said phuk it and built a new
faster box on 6.1 with apache22, the 5.1 sql server, and the latest
5.x PHP.

its been fine, and fast as heck.

IE: I gave up on finding the problem as its beyond my skills.

Re: two NIC and nfs

[Jeff Mohler]

Well..the right way to do this is with a switch that can etherchannel
the NICs together, im not sure if Fbsd can do that..of course.

But..are you really peaking out at 100Mb/sec with your existing NFS
architechture that you need a second pipe?

If you're not, I doubt a second pipe would speed anything up.

The server have only one purpose : nfsd.

Suppose if I do

nfs_nic_1  <---> client 1

nfs_nic_2  <---> client 2

well that's work but not... really because if incomming traffic from
client_2 pass through nic_2, all output traffic pass through nic_1.

How can I make the all traffic between client_2 and my server pass through
nic_2 ?

That was after I left Netapp for a spell (and later came back once the
vacation ran out) and it was supported before then by _something_
linux.

That was fall of 03.

Not trying to debate..just it'll still be 08 before it's likely to be
universally supported.

Hello,

As far as I can tell Linux only had mainstream/official iscsi support in
2.6.12 (2005-06).

Re: What's so compelling about FreeBSD?

Linux has iSCSI...which hands Fbsd a real beating in the server space.

I work on projects at more customers than I can keep track of that
-have- to use Linux in the middle of Fbsd farms just because of the
amazing lack of iscsi support.

Linux has been doing iscsi since what..2002 or so?  Maybe 2003?

C;mon..yes, I know a brave soul is starting work on it now, but how
did the Fbsd effort let this lie for so long?

Ah well, you have to experience it. No amount of convincing or intellectual 
gymnastics will help you.

Know that in the software ecosystem there is a place for everything.

There are situations in which you have to use linux and even Windoze.

But things are so vibrant that more and more Windoze apps are available in 
linux and FreeBSD and also in NetBSD and OpenBSD.

Personally for me linux has very good support for a wide range of TV cards, 
remote controls and other rare hardware.

BSDs also have support but somewhat limited.

FreeBSD gives you CCD,GEOM,GDBE, netgraph and various other features hard to 
find in other OSes. Some equivalents exist but not as good.

OpenBSD has very good IPsec , pf , BGP and other networking stuff. pf is also 
available on FreeBSD but I doubt if it is as well integrated and feature rich 
as OpenBSD.

Linux has a lousy file system and is somewhat unstable and will throw surprises 
if you stress it or use it in unexpected ways.

Whereas BSDs have very very good stability. For instance FreeBSD will give 
roughly 20 to 30% better overall performance compared to Linux. This is 
subjective and dependent on various factors but this has been my experience.

In terms of packages FreeBSD I think has the largest number since it can 
emulate linux binaries too.

I can go on but I suggest you try things with an open mind.

If you like it, stick to it , else go back.

Nobody is forcing you.

But remember, give it enough time and be open.

Girish

NFS Client..attr caching..

[Jeff Mohler]

here at work we want to compile deep trees of code on Fbsd boxes, but
we are finding that the compiles on local disk are faster than via NFS
(very very fast/new Netapp boxes) on the FreeBSD boxes (single spindle
SATA drives).

However, cross-compiling the same code on a linux box over NFS to the
very same Netapp boxes is way faster than Fbsd on local disk.

Im trying of course to get the mount options/etc that the linux boxes
use, but any clues on how to mount a 150k file deep source tree to
most effectively cache getattr/readdir metadata which seems to be an
enourmous percentage of the total NFS calls in the compile process.

Thanks in advance..as I get more data.
