I'd say go with FreeBSD 9.0, either 9.0-release or 9.0-stable snapshot.

I ddon't see any advantage in FreeBSD 8.x or earlier.

One thing I didn't like about FreeBSD < 9 was distribution sets broken into 
floppy-sized chunks (base.aa, base.ab ...)
which is no longer the case with 9.0.

For C programming, you have the choice between gcc and Clang.  

I like Gnumeric spreadsheet.

Something is definitely not right with your system.  It really shouldn't
be that painful.

The missing package database entries can usually be recovered by forcing
a reinstall of the package over what is already on disk, but if
everything is working properly, I wouldn't worry too much about the
contents of /var/db/pkg.

I'm thinking that having the registry of installed ports in a completely
separate partition or ZFS (ie /var) to where the ports are installed
(/usr/local) is not ideal, especially when using snapshots to provide a
roll-back capability.  /usr/local/var/db/pkg perhaps?

Yes -- you could well be having hardware problems.  Try a few passes of
memtest86.  It's in ports, but it's a standalone application you boot
into so concepts of compatibility with particular OSes is irrelevant.

Also do the usual stuff removing any dust or fluff that may be clogging
up the ventilation holes or heatsinks, check that you've still got a
good thermal contact between the heatsink and CPU (replace thermal
compound if necessary).  Also make sure your power supply is up to the
job.  They can fade over time, or you may have added a peripheral too
far.  [Although generally if anything here was wrong, you'ld see the
machine crashing and rebooting rather than it affecting use of the ports...]

Why did you define WITHOUT_CLANG?

On 10.0-current amd64 I build the world/kernel

I may be mistaken but I would guess it has to do with the
vulnerabilities addressed in OpenSSL in the 30/05/2012 update.

I'm assuming authors have bumped their ports' revision numbers to force
a rebuild, using the patched openssl lib.

Re: Anyone using freebsd ZFS for large storage servers?

[Wojciech Puchar]

48TB each, roughly.  There would be a couple of units.  The pizza
boxes would be used for computational tasks, and nominally would have
8 cores and 96G+ RAM.

Obvious questions are hardware compatibility and stability.  I've set
up small FreeBSD 9 machines with ZFS roots and simple mirrors for
other tasks here, and those have been successful so far.

Observations would be appreciated.

you idea of using disks in JBOD style (no "hardware" RAID) is good, but of 
using ZFS is bad.



i would recommend you to do some real performance testing of ZFS on any 
config  under real load (workload doesn't fit cache, there are many 
different things done by many users/programs)  and compare it to 
PROPERLY done UFS config on such config (with the help of gmirror/gstripe)


if you will have better result you certainly didn't configure the latter 
case (UFS,Gmirror,gstripe) properly :)


in spite of large scale hype and promotion of this free software (which by 
itself should be red alert for you), i strongly recommend to stay away from it.


and definitely do not use it if you will not have regular backups of all 
data, as in case of failures (yes they do happen) you will just have no 
chance to repair it.


There is NO fsck_zfs! And ZFS is promoted as it "doesn't need" it.

Assuming that filesystem doesn't need offline filesystem check utility 
because it "never crash" is funny.


In the other hand i never ever heard of UFS failsystem failure that was 
not a result of physical disk failure and resulted in bad damage.
in worst case some files or one/few subdirectory landed in lost+found, and 
some recently (minutes at most) done things wasn't here.



if you still like to use it, do not forget it uses many times more CPU 
power than UFS in handling filesystem, leaving much to computation 
you want to do.


As of memory you may limit it's memory (ab)usage by adding proper 
statements to loader.conf but still it uses enormous amount of it.


with 96GB it may not be a problem for you, or it may depends how much 
memory you need for computation.




if you need help in properly configuring large storage with UFS and 
gmirror/gstripe tools then feel free to ask

Re: Anyone using freebsd ZFS for large storage servers?

[Wojciech Puchar]

I'm not using as huge a dataset, but I was seeing this behavior as well when 
I first set my box up.  What was happening was that ZFS was caching *lots* of 
writes, and then would dump them all to disk at once, during which time the 
computer was completely occupied with the disk I/O.


The solution (suggested from ) for me 
was:

vfs.zfs.txg.timeout="5"


both problem, and solution is very close to linux style ext2/3/4 and it's 
behaviour. And one of the main reason to moving out from this s..t to 
FreeBSD. (the other was networking)


UFS writes out complete MAXBSIZE sized chunks quickly.


all of that behaviour or linux (and probably ZFS) are because it often 
gives better result in benchmark, and people love synthetic benchmarks.

I had the same problem a while ago with my ISP (Plusnet). Standard response 
from front line support is to say you need to send a copy of the message that 
you never had. Eventually I diverted my questions@ mail to a server that I 
had control of and relayed the messages from there to my ISP account so I 
could monitor the logs. The spam was being rejected with "552 Spam Message 
Rejected" and no information was returned to identify the email. Most of the 
rejected mail was spam but there were a small number of false positives. When 
I managed to get past the ISP's  front line support they removed the 
addresses for the false positives from the blacklist but this is only a 
temporary fix since more addresses keep wrongly finding heir way onto the 
list over time, though they do eventually drop off it again.

Plusnet use Cloudmark spam filtering and I see from the OP's headers that 
Insight also use Cloudmark so I'd expect similar things are happening there. 
I was able to stop the bounces by adding freebsd.org to the whitelist on my 
ISP account - but with the downside of seeing more spam on the list.

There might be a little of that, but most of the recent activity is
accounted for by

   * Numerous ports moving to the new OPTIONSng framework

   * Hundreds of PORTREVISION bumps after an update to graphics/png

   * Removal of old koffice ports and the import of the Calligra office
 suite to replace it.

It's there. As I said, using a USB 3 *Stick* works fine. It is recogized as 3.0

both umass devices. I don't need to boot from that disk, I just want to use it

vpn speed loss

[Beni Brinckman]

Hi,

I'm running FreeBSD 9.0-RELEASE (pc-bsd 9.0 actuallly) on amd64 and
I'm using a vpn connexion.
My problem is the enormous speed loss i'm having when I'm using the
vpn connexion.
I have tried Openvpn and mpd5 (with a pptp and l2pt connexion) and the
max speed (according to various speedtests) is 5 to 6MB.
Without the vpn I'm having 45-50 MB... My vpn service has servers in
several European countries and US, Canada, etc. The speed stays the
same.
So I don't  think it is a specific bsd problem but the lines/connexion
between ISP's.
Is this the "normal" speed when using a vpn (independently of the used
program to connect) ? Because from 45-50 back to 5-6 is a big step
backward...
Thanks for any insights here.

5-6MB = megabytes per second? megabytes per hour? per year?

do not expect high performance with VPN and ESPECIALLY on this protocols.

no idea really how openvpn works, but if you can choose between TCP based 
and UDP based VPN then try both.


UDP is better in protocol point of view but it may be bad for OS overhead.

TCP is better with OS overhead but may result in retransmit mess when 
there are packet loss (both native traffic is retransmitted and then 
virtual traffic)

Yes, but this was only on a USB2 (two) port, and just an auxiliary
information, to show the drive is not dead or otherwise funky.
Once I get it running, I'll put an UFS2 on it.

My goal is to get it recognized on one of the two USB3 ports I have.
All I get there is

Jun  1 11:43:45 hal9000 kernel: umass0:  on usbus4

(disconnected)
Jun  1 11:45:26 hal9000 kernel: umass0: at uhub4, port 2, addr 1 (disconnected)

There never is a device node like /dev/daN created, like it does
for the USB 3.0 *stick* I have.

PV> xterm works for me in my mutt under tmux, ask me if you need to tweak 
locale ( I see his L char with the '/' over it in place, and the cyrilic

PV>

should be shown better in mlterm rather than in xterm.

I have to correct myself here: xterm-261 'just works'  but not xterm-279 that 
is an up to date port. I have just fixed my cyrillic and pdeudo-graphics by 
backing off x11/xterm to '261' version.

Of course I borrowed with those +/- for 'wc', 'lc', 'u8' stuff and none of them 
made 279 to behave the same as 261 for non-ascii.

zfs scrub...???

Additionally ZFS works directly at the block level of the HD meaning
that it is slightly different to the 'normal' file systems in storing
information and is also "self healing"..


Though I'm sure that you knew all this and have found otherwise.


I mean I haven't found any problem with it even after power failures
and such and my machine has been up for nearly 3 years.

It was my impression that ZFS doesn't actually format the disk as
stores data as raw information on the hard disk directly rather then
using an actual "file system" structure as such.

That's what I was trying to get at by that statement. This is really
what made ZFS standout over other types of file systems.


In doing that according to everything I have read, it actually means
faster I/O and ease of portability incase the disks need to be removed
from their current location and added elsewhere but not loosing
information.


Unlike clunky hardware RAID systems ZFS adds much more versitility too
which of course being at this depth of knowledge you are aware of and
may even have a means to compare, however I personally prefer it over
RAID as RAID is rubbish dealing with it everyday I am fed up of
creating non-dynamic arrays.


I cannot compre directly to the more advanced UFS2 techniques but my
money would be with ZFS over RAID and LVM any day and don't even give
me M$ systems they would be out the window before being booted for the
first time..

If the OP really intended to stripe disks with no parity or mirror for ZFS 
, then that is probably a mistake. If the disks are /tmp, it might make 
sense to stripe disks without parity, but no need for ZFS. The OP did say

"JBOD", which to me means that each disk is a separate disk partition with
no striping or parity. Again, in that case I don't see any need for ZFS.

As for ZFS being dangerous, we have a score of drive-years with no loss of 
data. The lack of fsck is considered in this intelligently written piece

In worst... in ultra-worst abysmal inexpected exceptional
and unbelievable narrow cases, when you don't have or can't
access a backup (which you should have even when using ZFS),
and you _need_ to do some forensic analysis on disks, ZFS
seems to be a worse solution than UFS. On ZFS, you never
can predict where the data will go. Add several disks to
the problem, a combination of striping and mirroring
mechanisms, and you will see that things start to become
complicated.

I do _not_ want to try to claim a "ZFS inferiority due to
missing backups", but there may be occassions where (except
performance), low-level file system aspects of UFS might be
superior to using ZFS.

does any filesystem "format" a disk?
disks are nowadays factory formatted.

filesystem only write data and it's metadata on it.

even if some sectors are overwritten with garbage then fsck can scan over 
inodes and recover all that can be recovered.



ZFS is somehow in that part similar to Amiga "Fast" File System. when you 
overwrite a directory block (by hardware fault for example), everything below that 
directory will disappear. You may not be even aware of it until you need 
that data


Only separate software (that - contrary to ZFS - do exist) can recover 
things by linearly scanning whole disk. terribly slow but at least 
possible.




EVEN FAT16/FAT32 IS MORE SAFE.

If you have an operational need for offsite backups, that doesn't
change no matter how much redundancy you have in a single location.
Backups are still necessary.

But when RAIDed, ZFS has features that make it superior to hardware
RAID - copy-on-write, block deduplication, etc.  Like UFS2, it
supports snapshots - but a lot more of them.

Another performance criterion that is important to me is mirror (or
raidz) recovery - how long does mirror catch-up take when you replace
a disk, and how badly does it degrade performance for other data
operations?  Software raid, esp. gmirror, tends to do poorly here.  My
experience is that ZFS raid share recovery had less of an impact.

YMMV.

you are just lucky.

before i would start using anything new in such important part as 
filesystem, i do extreme test, ssimulate hardware faults, random 
overwrites etc.


I did it for ZFS not once, and it fails miserably ending with 
unrecoverable filesystem that - at best - is without data in some 
subdirectory. at worst - that crashes at mount and are inaccessible 
forever.


under FFS the worst thing i can get is loss of overwritten data only. 
overwritten inode - lost file. overwrite data blocks - overwritten files. 
nothing more!



what i don't talk about is ZFS performance which is just terribly bad, 
except some few special cases when it is slightly faster than 
UFS+softupdates.


It is even worse with RAID-5 style layout which ZFS do "better" with 
RAID-Z.

What an entirely useless performance measure!  Maybe you should
restrict yourself to
using SSDs, which have rather unbeatable random read performance - the

First of all, in any environment you expect disk failures.  Which
operationally means replacing the entire disk.  Then you rely on the
raid recovery mechanism (in whichever flavor of disk discipline you
choose).  ZFS semantics (copy on write, for example) are much safer
than UFS semantics.  This is not to say that UFS is not a more mature
and possibly robust filesystem.  But relying on gmirror, graid, etc.
means you are no longer relying solely on the robustness of the
underlying filesystem - you cannot offer a reduction proof that shows
that if gmirror is bad, it means UFS is bad.

I use UFS for most purposes, but would never build a large fileserver
using gmirror on UFS.

Your assertions about the dangers of ZFS are just that - assertions.
They are not borne out in reality.

On the other hand, even on a single-disk pool, ZFS stores two copies of all
metadata, so the chances of actually losing a directory block are extremely
remote.  On mirrored or RAIDZ pools, you have at least four copies of all
metadata.

Re: Anyone using freebsd ZFS for large storage servers?

[Oscar Hodgson]

Thank you for bringing up this topic.

We've got significant experience with both UFS and ZFS (as delivered
by Solaris).  Our internal testing has shown that UFS provides
significantly better throughput, roughly 20% to 30% higher in general,
and 50% higher in some specific use cases.

My internal customer prefers ZFS's 'end-to-end' reliability guarantee
to the higher throughput of UFS.

(What's really interesting though is that he's really a long-time
Linux fan at heart ... and we are now discussing FreeBSD due to its
ZFS support.  A Linux hardware RAID solution is not presently on the
table).

ZFS really is entirely different than UFS.  In 2005 Bonwick put out a
presentation roughly titled, "ZFS the last word in file systems".
I've used those materials on a number of occasions to help explain the
difference between ZFS and prior generation file systems.

Are you running FreeBSD 9?

Most of the LSI drivers officially support 8.2, but I don't see any

Work very fine (I can't say I've long experience because the server is up

The ZFS is very good, easy to manage, very fast.

then install /usr/ports/benchmark/randomio and do some tests of random 
reads on that files.


and final test - 10 randomio in parallel with 10 threads each, one per 
every file.


then sum up results (IOPS) and divide by amount of disks you have.

then decide if is it fast or slow :)


They're two default IMHO :

       Eat lot of Ram


can be controlled by settings in loader.conf.

When I say fast that's mean I already do some benchmarks with iozone. And
do some graphs to see what the performance are. 

What I can say is it's go lot faster than H700+ 12 disk 600 15k/min. 

And I do those tests on FreeBSD with 12 disk, 24 disk, 36 disk and finaly
48 disk. 

All I can say is ZFS go faster than 12 disk with H700 (and ext3) almost
every time. 

If you like I can privalty send you the url of those graph. Just ask me,

Yes, but I think that's not a good idea to buy a server with 4 Go and make
him manage 100To through ZFS

I am in the process of trying to sort mine out.
Found this via one of the hp linux support pages
  http://hplipopensource.com/hplip-web/support.html
I'm in the process of trying to get mine working with their help.
We'll see how that goes; will post results.

In my case (network connection) they suggested running and sending them the 
output of:

$ hp-check
$ hp-probe -ldebug
$ hp-makeuri -ldebug 
$ hp-setup -ldebug 

I'm in the process of sorting that out, as it may be an issue of how cups and 
dbus are installed which may be preventing access (file ownership issues)

I added a HP Photosmart C6300 series via CUPS using HP Photosmart c6300

hp-check indicated what it thought were inconsistencies;
things it couldn't find but should have because they were there.
the output didn't jibe with file permissions and running daemons,
but I did see one potential issue (a missing python capability which was not 
one of the defaults.  can't remember which, maybe in the cups install)
I did a make clean, make config, make install, and that got me a lot further.
In the config, I think for something cups related, I checked the python 
capability.

When I run hp-setup now, it finds the printer, but it can't find an appropriate 
ppd file.  
Working on that now.
The right one is there, but for some reason it claims it's not a close-enough 
match.

Any chance you have access to a 3.0 drive from a different mfg you can try to

That was part of their assumption. It's based on server grade hardware and

Yep, big time. Hardly as in hard, not as in barely.

Re: Support for Intel 82599ES?

[Rick Miller]

Thanks, Michael!

I took a look at the manpage and it does appear that it is supported
by the bge driver.  It also states that the 572x controller is also
supported, but I heard a rumor stating that the BCM5720 in particular
did not work even though the manpage indicates it is supported.  I was
unable to verify this, but that's why I was asking for clarification.

I will assume it works at this point.

How to crontab screen with script inside and a "don't run it if it's already running" check?

[Dwayne Henderson]

I run this Ruby script 24/7 (records data from this live stream). It runs
inside a screen though, so it's easy to check in on it every once in a
while.

But how do I crontab the screen with the script inside it? It has to be
with a "don't run it if it's already running" check.

So far I have this (untested) - what y'all think?

*/10 * * * * lockf -t 0 /home/anonymous/.myscript.lock

maybe you should create a shell alias. I do the following for my irssi
session:

# Start irssi within screen or switch to it if it is already running.
alias irssi='if pgrep -u $USER irssi;then screen -U -x irssi;else screen -S 
irssi irssi;fi'

Probably ok if you soldered it up so you didn't have the mismatch from crappy 
high impedance plug-in connections. You don't happen to know if the analog out 
(back of drive plug, not the headphone jack) impedance and signal level on a cd 
is close to matching the line-in on a card, do you?  I'm guessing not.  Most 
likely would smoke the card/mobo.

It looks to me like a digital audio channel won't show up under any 
circumstances;
it will take a second bridge driver designed to eat cd digital audio,
and the overarching sound driver could pick that up.

>From my (limited) understanding as a result of this discussion, 
it looks to me like freebsd doesn't work with digital cd audio at all.
If there's no general device to pick up digital audio from the cd,
the only way the sound driver could get it would be for a bridge driver,
or the sound driver itself, to pick up the cd digital audio and present it.
It's difficult to believe that a normal sound bridge driver would be reaching 
out to a different device and doing that.  

As it stands, cd audio seems to work by picking up the analog audio output and 
converting it.  Which is what you told me in the first place in less detail :-).

Correct me if I'm wrong...

My system is FreeBSD 9.0 Release and the lst time I use Clang. It works very 
good but the lst problem was with Calligra which didn't built.

As I red in /usr/ports/UPDATING I ran portmaster -r png- and there are so many 
ports which should be rebuild. 
My question is: Is it better (safer) to use gcc or try clang? Or is it better 
to not update png?

Thanks in advance.

Well, I still see complains about a few quirks in 9 here in the list, 
specially after certain src updates.

Etc ..

To me, something like pf (specially route-to!) is critical and for the moment, 
I wouldn't touch my rock-solid-down-to-the-micro-second perfect production 
firewall 8-STABLE server for nothing, if the aim is such a role.

I think that distribution set size is just not a very strong argument.

OTOH, if the aim is just experimenting, that's another story.

Why did you define WITHOUT_CLANG?



I think I am stuck at 9.x because of the clang stuff.

I defined WITHOUT_CLANG to stop make buildworld from building clang.

Warren, 

Thank you very much for the useful tips. One more question regarding
SSD. The FreeBSD installer enabled journaled soft-updates on the 
filesystem which resides on the SSD. Is it good, bad or irrelevant for
the SSD ?

/dev/ada0p2 on / (ufs, local, noatime, journaled soft-updates, nfsv4acls)

Re: FreeBSD on the ASUS P8H67-M LGA1155 H67 motherboard

[Victor Sudakov]

I have installed 9.0-RELEASE on this motherboard with the following
brief results:

$ cat /dev/sndstat
FreeBSD Audio Driver (newpcm: 64bit 2009061500/amd64)
Installed devices:
pcm0:  (play/rec) default
pcm1:  (play/rec)
pcm2:  (play)
pcm3:  (play)
pcm4:  (play)
$

The devices /dev/dsp0, /dev/dsp1 even play to different audio outputs
(front panel and rear panel). 

However, there are some more or less serious problems:

1. The "green" console screensaver does not poweroff the monitor. It just
blanks the screen and sometimes displays white rubbish thereon.

2. It looses one of the HDDs during intensive read/write operations:

Jun  2 00:55:33 vas kernel: ahcich1: Timeout on slot 4 port 0
Jun  2 00:55:33 vas kernel: ahcich1: is  cs 00c0 ss 00f0 rs 
00f0 tfd c0 serr  cmd c617
Jun  2 00:56:48 vas kernel: ahcich1: Timeout on slot 0 port 0
Jun  2 00:56:48 vas kernel: ahcich1: is  cs 0001 ss  rs 
0001 tfd c0 serr  cmd c017
Jun  2 00:57:20 vas kernel: ahcich1: AHCI reset: device not ready after 31000ms 
(tfd = 0080)

I shall of course check the HDD and cable, but they worked flawlessly on
the previous system.

3. I had to run xorg in VESA mode, because xf86-video-intel-2.7.1_4 does
not recognize the video chip on the motherboard on question. That is a
pain! mplayer is incredibly slow on all movies. It complains that "your
system is too slow to play this" and gives a plethora of obscure
recommendations, but I basically thought that the sheer CPU power should be
sufficient to play the video. Is there a solution which "just works"?
Replacing mplayer with something else? Buying a video card (what model)?
