RE: [CentOS] DJB's daemontools package

[Al Sparks]

I was going to recommend roughly the same thing.

Don't use RPM's, install his tools manually.

When I did, I learned a lot of useful information about the internals
of RedHat/CentOS (or any System V LUnix system for that matter).

And with all due respect, of course, it brings me back to the days
when I was managing a qmail server and hanging around the qmail
mailing list.

There was a lot of rudeness and snarkyness on that list.  They
aren't kind to those they consider fools.

DJB has his acolytes, much like Linus Torvalds does.  I suspect that
DJB's personality reflects the overall tone of DJB related online
communities, much like Torvalds's personality affects groups like
this.  I have to say, DJB's software offerings are top rate.

Oh and the qmail server?  My employer went Exchange.  And slowly
but surely, the IT there is becoming more Microsoft with Linux
becoming more of an outlier.  It's probably time for me to find
another job.  It's hard, because I've been with them a long time.

Or its time for you to make a direct presentation to the upper level
management showing that the number of direct staffers  needed to
administer an MS environment is between 15 and 300% higher than
a corresponding UNIX/Linux environment. 

Why "Upper management" and not IT management?  Because IT management
BENEFITS from having more staff to manage.  When your headcount
increases and your budget is larger, your management importance 
and status goes up and you become recognized as a "peer" of those
who may become the next CEO.

UNIX/Linux is bad for the IT empire builders because it is good for the
rest of the company. It reduces costs and headcount while increasing 
increases reliability and security at the same time.

Infrant was bought by Netgear.


Sure it had many cool features like their X-Raid technology.  The casing

and the ReadyNAS was choppy.  It seems to be weak at multitasking

was glitching while i was doing a "filesystem search", not cool for a DJ!


I replaced the thing by an Asus micro-ATX mainboard and an Athlon Dual

i had on the ReadyNAS (Western-Digital 500 Gigs RAID Edition) and i do

35-40 MB/s and the cpu usage is low).  I experienced the Samba problem

[CentOS] bonding theory question

[Mag Gam]

Hello All,

I am currently using bonding with 2 NICs (using mode 0). Its been
working well, but I am trying to understand how it works (I am a total
newbie).

mode=0 (balance-rr)
Round-robin policy: Transmit packets in sequential order from the
first available slave through the last. This mode provides load
balancing and fault tolerance.


So I have 2 NICs (1 NIC attached to switch A, 2nd NIC attached to switch B).

I have 1 virtual interface. bon0.

Suppose data is being pushed out, it will go with 1st NIC and when it
gets overloaded it will use 2nd NIC. The bonding driver will be
responsible for it.

Similar to the push, the pull will be very similar. The data gets
pulled and the bonding driver will assemble the packets together? Does
this sound right?

Sorry for a newbie question...

TIA

 Jeff is correct

If you look at the IT manpower and how the org charts play. The
windows support staff will map out to more managers and more managers
of managers.

The side effect is that the audience of any presentation will be level
mismatched.
Windows oriented managers  will be pitching budget and needs two or
three levels above a Linux support staff doing the same work simply
because the staff size mismatch.

At a previous Unix based hardware computer company I did some
curiosity driven research and noted that the company had more staff
(mostly contractors) supporting windows for the internal "needs" of
the company than the company had support staff (both hardware and
software) for the paying customers.  The organization structure was
disjoint and difficult to map At times a windows support
person would show up to fix "something" I would look at the name tag
and try to find what group the person was in and most often I would
not have considered it a windows support group.

Much of the Unix support was done in the spare time by a handful of
folk where the Windows support was managed by a 'staff'.   Very
different staffing and management  model

Also there is the comfort factor -- schools teach Windows stuff in
computer science departments.  Managers and sales staff that can type
know outlook, excel and word.

To complicate this, legal requirements mandate lots of stuff.

In the 'free' software universe we live in it is hard to comprehend
how much money is spent to guarantee that all software is legal.
Compliance in this regard costs a lot.

Of interest the Unix community and the Windows world have very
different security models.   For the most part Unix is transparent
while windows is opaque.   There is a reason that VMS was so
popular

No. If you are using "balance-rr", one packet will go through the 1st
NIC, and the next packet will go through the 2nd one. That's what "rr"
(round-robin) means.

Actually this will not be determined by the bonding driver, it will be
determined by the switch that is actually "pushing" the packets. The
bonding driver will only make it look like the packets are coming from
one (bonded) interface only.

How the switch will behave depends on its configuration. It may be
configured to send all the data through one of the interfaces only to
balance through both of them using round-robin or something else.

You should try to read this, it's very complete:
/usr/share/doc/iputils-*/README.bonding

Also, if your switch supports it, you should try to use the 802.3ad
mode (mode=4) since that will probably give you the best results with
bonding (in terms of load balancing and fault tolerance).

HTH,

Oops, the word *source* can get you huh...  ;->

What I actually recommended was going to the source website to fully

At the source website you can get the software source and the reasons behind
it.

One can google for more info after that.

I believe the OP is/was more than intelligent enough to get source and
implement etc.

I was a little ambiguous and I can do better in my "language" too.   :-)

Anyways, one should know how to install that software and use it from source
on a test box before looking for an RPM for several reasons...

There are issues with certain versions of software that have to be
compensated for and you want to make sure that any rpm is for your distro
and was rolled properly.

Bottom line, some software (both in this case if I remember right) do or
used to need to be *errno* patched, and may still need to be patched
depending blah blah.

Simple patches, yet patched none the less.

Qmail??? That thing that would accept all messages from a dictionary

on some widely-sold list for spamming.  Even after replacing the mailer 
with something that quickly rejected invalid local addresses, I kept 
getting about 50,000 spam attempts a day for years to those addresses.


And wasn't bright enough to send group messages to the same host

I don't see why anyone ever put up with it, especially when the license

Thankyou! Your explanation helps a lot. Its makes more sense than

Actually, would there be a big performance boost when using mode4?
Currently I am seeing 95% total throughput. Which isn't that bad. I am
peaking at 238MB/sec (each gig/e connections)

Also, mode0 does fault tolerance, meaning if a switch failure occurs
we should still be good, but how would the packets then be
transferred? I suppose rr would be disabled since it won't need to
alternate, correct?

you should use the lock databases option so you can get

or the single transaction option (again, with InnoDB).


and better yet, he can first replicate it to another server, and do the 
dumps there (when he can stop replication while doing the dump).



of course no changes to the DB will
be possible during the backup. mysqldump also does not
back up user permissions/accounts. So you'll have to re-create
those on the other side.



it does if you dump the whole thing.


Any recommendation 


For InnoDB there is a commercial hot backup app for it,
which is about $1500/server for a perpetual license:

http://www.innodb.com/hot-backup/

What I did at my last company was shut down the standby
mysql database, snapshot it from the storage array, start up
the database(this entire process takes about 35 seconds),
export the snapshotted volumes to a 3rd server and back it
up there, then delete the snapshots after it was done.

sample log file:
http://portal.aphroland.org/~aphro/san/mysql-backup-prod-backup-2_20080319_070501.log

It worked beautifully, reduced standby downtime from ~3 hours
to ~35 seconds, and allowed the standby dbs to actually be
standby dbs. Also allowed consolidation of several different
backups onto a single system.

If you don't yet have a standby database and want to build
one you could do something similar, take the primary down
for a few seconds to snapshot it, and then put the snapshot
on another system for restoration onto a fresh volume to
populate the initial standby.

Of course to do that you need good storage infrastructure,
not sure what yours looks like.

Not necessarily, since balance-rr already gives you load-balancing.
They actually implement it differently. balance-rr can spread packets
of the same TCP connection across the two links, so you may use your
links more, but with the side effect of having your packets delivered
out of order. In 802.3ad all packets of a single TCP connection will
use the same link, this means your links will not be as balanced as
what you get with balance-rr, but it will not require reordering on
the other side of the connection. Check section 12.1.1 in
/usr/share/doc/iputils-*/README.bonding . In any case, you should
evaluate what your needs are and tune for that.

> Currently I am seeing 95% total throughput.

If you have only a few clients doing huge transfers, 802.3ad will
probably not be as good as balance-rr for that. Again, you should tune
it for your needs.

> Which isn't that bad. I am

I believe you mean 238MB/sec on both interfaces, since 1Gbps = 125MB/s.

Actually balance-rr is still there, it is only doing round-robin of
one interface only. Remember, you could have a bonding of 3, 4 or more
interfaces, in that case if you loose one you still have more than one
to balance traffic through.

[CentOS] Time delaying (or time lagging)

[happymaster23]

Hello everyone,

I have problem with time delaying on my CentOS powered server. I have tried
to set time in BIOS and in OS (with saving time to BIOS), but time still
delaying, so after month is about five minutes delayed. In past I was using
this box with Windows and there wasn´t this time problem, but I cant
warrant, that there are no hardware issues. So I was decided, that easiest
way to fix this problem will be setting up the NTP. I have found many
howtos, but I don´t believe them. So my question is: How to clearly set NTP
in CentOS 5?

Nicholas: Thanks! One of the problems newbies have is which command to
use. Locate will help, when I'm trying to find something! Lanny

Re: [CentOS] Time delaying (or time lagging)

Hello everyone,

I have problem with time delaying on my CentOS powered server. I have 
tried to set time in BIOS and in OS (with saving time to BIOS), but 
time still delaying, so after month is about five minutes delayed. In 
past I was using this box with Windows and there wasn´t this time 
problem, but I cant warrant, that there are no hardware issues. So I 
was decided, that easiest way to fix this problem will be setting up 
the NTP. I have found many howtos, but I don´t believe them. So my 
question is: How to clearly set NTP in CentOS 5?



   # yum install ntp

then, edit /etc/ntp.conf, and at a minimum specify some ntp servers and 
restrict access to localhost...


   restrict 127.0.0.1
   restrict -6 ::1

   # Use public servers from the pool.ntp.org project.
   # Please consider joining the pool (http://www.pool.ntp.org/join.html).
   server ntp1.sf-bay.org
   server ntp2.sf-bay.org
   server reloj.kjsl.com
   server ntp1.mainecoon.com
   server ntp2.mainecoon.com
   server time.berkeley.netdot.net



(note, those are the LOCAL TO ME ntp servers that *I* am using, you 
should undoubtedly use others as appropriate, or use the pool servers... 
see http://ntp.isc.org/bin/view/Servers/WebHome for guidelines)...


finally...

   # chkconfig ntpd on
   # service ntpd start

and wait about 20 mins for it to sync up, and verify functionality with 
ntptrace...


   # ntptrace
   localhost.localdomain: stratum 3, offset 0.004351, synch distance 
0.088396

   zorro.sf-bay.org: stratum 2, offset 0.000543, synch distance 0.044773
   clock.via.net: stratum 1, offset 0.27, synch distance 0.000446, 
refid 'GPS'


if your systems clock is particularlly funky, it may be a good idea to 
edit, /etc/sysconfig/ntpd  and set SYNC_HWCLOCK=yes rather than no.
(this tells it to set your HW CMOS clock when it sets the system clock 
during the initial synchronization)
