[CentOS-virt] Virtuozzo GFS

2008-05-31 Thread James Thompson
I have just finished deploying two Dell PowerEdge 1950s with CentOS 5.1 and
Virtuozzo 4. GFS is up and running and Virtuozzo is configured for
shared-storage clustering. Everything works adequately but I am wondering if
anyone else has experienced load issues like I am seeing. I have three
VEs/VMs running, two on one node and one on the other node. One of the VEs
on each node are doing very little (one is just idling with apache and mysql
and the other is running rsync every six hours). The other is running
Zimbra. Every so often load will spike on the node running the Zimbra VE to
as high as 2 or 3 then settle down a short while later to around 0.8 or 0.9.
During the spikes the node not running Zimbra will other see an increase
from its idle load of 0.4 or so up to as high as 1.7 as I have seen. I
notice when running top that dlm_send and dlm_recv will jump to the top
fairly frequently when these load spikes occur.
What I am wondering is whether anyone else has experienced these kind of
load scenarios with GFS and what they have done to deal with them? We are
hoping to deploy a bit more densely on this setup so I'd like to make any
performance adjustments I can at this stage.

A load of 2-3 isn't much at all... so I don't think I'd call that much of a 
spike.  I have run OpenVZ at work and on a hobby server.  In both cases I have 
about 7 containers... one of them being Zimbra.  The other 6 containers are 
fairly busy so the two machines see a decent amount of load.  I am NOT using 
GFS though.  What is dlm_send and dlm_recv part of?  GFS?

Re: [CentOS-virt] Virtuozzo GFS

2008-05-31 Thread James Thompson
I believe both dlm_send and dlm_receive are part of GFS' locking mechanism
where locks are bouncing back and forth between servers. The Zimbra VE is
pretty consistent in its internal load and what struck me was that
Virtuozzo's PIM interface flags the increased load (leading me to believe it
is abnormal). Perhaps I am mistaken on the meaning of the load figures
though. On a busy machine what would be considered a normal load? Does it
differ based on the number of processors and cores available in the system?
I came across this article which makes me think I may be mistaken in my
concern: http://www.linuxjournal.com/article/9001

Can anyone who is using GFS perhaps comment on how it has performed for them
in virtualization scenarios? When initially working with just the iSCSI
mounted disks involved operations were just slightly less snappy than
local file operations. With GFS things seem at least noticeably more
sluggish which I expect is normal given the multi-server locking but has
anyone worked on optimizing GFS performance in a virtualization environment?

James Thompson

James,

I haven't personally used GFS before, but the sysstat package might be
able to help you out. Basically, from what i can see there would be two
different causes of the load:

CPU:
We've ran Zimbra in VMWare Server with an average load average of around
2-3 (exactly what your seeing) using Full Virtualisation via Intel VT
(ensure your Dell 1950 has this turned on via BIOS - it's not on by
default). Here you would probably see 'top' claiming the load average
(on the hypervisor) to be mostly on CPU.

IO:
Use the sysstat rpm (iowait app) to have a look at iowait times and
narrow it down to a IO problem, here you'd see 'top' claiming high load
average but CPU's look fine. We ran iSCSI on a 50mbit link (quick test),
and whilst formatting the load average shot up to ~5, CPU and everything
was fine and iowait quickly showed us it was waiting on IO the whole
time.

Hope that might help, you've probably checked these already though.

Does Virtualizzo supper paravirtualised guests - that might be the next
step to check out if you haven't already...

[CentOS-es] Consulta RAID 1

2008-05-31 Thread Richard Ramírez
Title: Richard Ramrez Ortiz




Buenos das, 

Ayer estuvo probando en un servidor HP Proliant un RAID1 con la
controladora que trae integrada(NVIDIA)
La creacin del RAID fue sin problemas a travs de la utilidad de
configuracin en el arranque, por lo que pude instalar el centos con
normalidad. Sin embargo, cuando quize probar quitando un disco y
colocando uno nuevo, no terminaba de arrancar el centos, indicando
errores con device is busy - kernel panic, previamente por
medio de la utilidad RAID hice un REBUILD de este con el nuevo disco.
Supongo que el problema es que si bien los 2 discos funcionan como raid
est aun no ha "reconstruido" la data en el disco nuevo. Debido a este
problema tuve que apagar el servidor y color el disco anterior, lo que
hizo que Centos arranque con normalidad. Cabe indicar que el RAID es
con discos SATA. Vi que en la web de HP existe una utilidad para ello
llamada ACU, sin embargo ya no se encuentra disponible. Espero alguien
me pueda sugerir algunas soluciones. Gracias.

mira, por lo que cuentas, el RAID1 es un raid por soft implementado a nivel de 
bios, posiblemente a nivel de bios de la tarjeta, es decir, para el sistema 
operativo debe de presentarsele un disco, digamosle virtual; si cuando le 
quitas un disco el linux no levanta, yo buscaria como funciona el raid1 de 
nvidea porque para mi es el culpable.
quizas tienes que dejarle que termine de reconstruir, quizas no.
quizas necesitas un driver, modulo del kernel de linux, mas nuevo que 
interprete correctamente el estado del raid1 que le suministra la tarjeta.

que version de centos estas usando?

yo me compre una pc recientemente y el controlador sata que tiene es nvidea, no 
esta soportado por centos-5.1, ni por centros4.6, creo que el centos5.2 lo va a 
soportar aunque no vi a que version del modulo sata sube, si es a la 2.3 lo va 
a soportar, el fedora8 (que trae la 2.3) lo soporta, tambien el fedora9 (trae 
la version3.0)

quieres probar si con una version del driver sata funciona bien?
prueba con un livecd de fedora8 o fedora9 en las mismas condiciones que el 
centos instalado falla

bueno, tienes una oportunidad interesante para jugar :-)

rsync command and altered it to go to localhost:/media/RALLY2/ (name

Huh?


So I try to just use mkdir to create a directory on the flash drive.  
The directory has a group of root ???


So I try a chgrp and get:

[EMAIL PROTECTED] me]# chgrp me /media/RALLY2/Stuff
chgrp: changing group of `/media/RALLY2/Stuff': Operation not permitted


OK why can't I set the group to something other than root?

ls -lstr /media/
total 4
4 drwxr-xr-x 3 me root 4096 May 30 16:28 RALLY2

and of course for /media:

8 drwxr-xr-x   3 root root  4096 May 30 16:18 media




Most likely the device is formatted as FAT32, which has no concept of
permissions.

Reformat it, ignore the errors, or modify your rsync command to not 
preserve

uid/gid.

Unfortunately, I have to use it on Win systems as well...


You can't expect it to maintain ext3 file permissions in a FAT32 
partition :D


you could use tar, but then the files are not available without untaring.

you MIGHT be able to also use acl permissions and getfacl/setfacl to 
build a permissions file which you can use to reset the permissions and 
still have the files available as normal files on the flash drive.

[CentOS] drbd strategy

2008-05-31 Thread sbeam
I have an existing in-production LAMP server running Centos 5.1. It uses 
physical partitions on top of hardware RAID1, having / /home /var and /boot 
on separate partitions.

We have a near-identical system I am thinking of bringing in as a 
DRBD/Heartbeat companion. One solution may be to use csync2 
[http://oss.linbit.com/csync2/] on /etc and /usr/local (the only areas that 
will differ from the stock CentOS). Then setup DRBD for /home and /var.

From reading the docs it seems we have to use external meta data on the 
existing partitions. Other than that, anyone have any caveats or better ideas 
for this setup?

Also - each has 2 NICs. Can Heartbeat do its pinging over the WAN (eth0) with 
eth1 dedicated to DRBD only? Is that how it is supposed to be, or should we 
use the serial ports?

You can decide on which nic heartbeat will do its broadcast ... serial 
port is optional and in certain cases it's even impossible to use serial 
port when machines are not located in the same computer room/building ...
Don't forget that if you use ext3 on your /home and /var partitions 
you'll only be able to use it on one node at a time .. if you need both 
nodes to read/write to the drbd devices, you'll need to use a clusterfs 
(like gfs, gfs2) on top

One KEY thing to understand about DRBD is that for the normal mode you 
CAN NOT mount the shared partitions on BOTH machines at the same time. 
(DRBD does have an active/active mode, but that is not it's major 
purpose ... DRBD is raid1 for partitions, so just like you can not write 
/ mount BOTH mirrors of a raid1 drive at the same time, you can't do 
that on DRBD either.)


If you really are trying to get a failover machine where you do not need 
to have both partitions mounted and active at the same time, then DRBD 
is probably what you are looking for.

sed can do anything (there is an example that implements the bc

correlating lines (actually, anything that involves more than
substitutions and deletion of lines -- s/// and //d) you would be
better off with perl or python.

I wouldn't bother learning awk, if you want to spend your time
learning something, go directly to perl or python. awk tends to get
very ugly when your script grows, and it does many things in an
AWKward way.

For text processing, Perl is still king. Python can certainly be used
for that, but even though I know Python well, for tasks such as the
one above I would choose Perl. The way regular expressions are
embedded in the language makes it very productive to work with these
problems.

Probably not a good idea to put the whole /var in DRBD, since then
the second machine will have it unmounted when it's in stand-by, and
there are somethings like /var/run, /var/tmp and /var/spool that
might be needed even if the machine is in stand-by. I don't think you
might actually be able to start heartbeat without a /var/run to
store its pid file.

You would be better off by using a DRBD partition for /var/lib/mysql
and leaving the rest of /var out of DRBD.

Not necessarily.  If the Linux files do not need to be accessed from the 
windows environment, you could create an image file, format the image as 
ext3, mount the image file as a loop device, and treat it as a standard 
ext3 mount point.


# create a 10M empty file

 Yum -upgrades works, but you'll potentially spend a lot of time clearing and
 fixing problems afterwards. You want a quick install, do a fresh one. Don't
 forget to backup your data first though.


I upgrade between minor releases, and that seems to work fairly well.
But for any major release, I'd go for a clean install.

 I will - thanks.

I did - no change.

 ...I think you need to pick a bit more on Windows networking...more reading
 of the books/documentation provided with samba should help.


Okay, I went through the Samba Guide at
http://us3.samba.org/samba/docs/using_samba.  I read chapters 1, 2  3
fairly thoroughly, and I'm going through 12 (troubleshooting) now.
One small problem is that this is for Samba 2.2 and I'm on 3.0.25.  Be
that as it may

Let me start up front with this: both Windows boots can ping the
CentOS Samba Server.  Neither one can see it in their M$ Network.

I went through chapter 3 step by step for both the W98 and WXP boots,
and I can't see my C5.1 from W98 at all, and I can't see anything
that's on the C5.1 from WXP.

I started going through the troubleshooting chapter, and I got up to
this point with W98:

'net use * \\mhrichter\tmp' hangs for about a minute, then comes back
with an Error 59 - unknown error.

In the log, I see this (I did it twice):

[EMAIL PROTECTED] samba]# cat mhrichter.log
[2008/05/31 10:54:03, 1] smbd/service.c:make_connection_snum(1033)
  mhrichter (192.168.0.100) connect to service tmp initially as user
nobody (uid=99, gid=99) (pid 19903)
[2008/05/31 10:54:07, 1] smbd/service.c:close_cnum(1230)
  mhrichter (192.168.0.100) closed connection to service tmp
[EMAIL PROTECTED] samba]# grep nobody /etc/passwd
nobody:x:99:99:Nobody:/:/sbin/nologin
nfsnobody:x:4294967294:4294967294:Anonymous NFS User:/var/lib/nfs:/sbin/nologin
[EMAIL PROTECTED] samba]#

In case you don't remember, the tmp share is configured thus:

[tmp]
comment = Temporary file space
path = /tmp
writeable = yes
guest ok = yes

So, in theory, anyone should be able to see it, read and write to it,
etc.  (Yes, I know there's a potential space problem here, but these
machines are all on a private subnet, I'm the only one who has a clue
how to really make use of them, and there's about 35GB left on /,
including /tmp.)

This particular problem is not addressed in the guide, so I'm stuck (again).

I'll be trying the WXP boot in a few minutes, where my logon /should/
work (but doesn't) and I'll see what turns up in the log for that.

But, in the mean time, any ideas?

Thanks.

In that thread, I was told to expect such things and test better

I think your reading the wrong guide, try this one and this has traversed on
long enough. Almost Two weeks now. Below included is also a work (BASIC)
Configuration file to get you going. Then you will need to go on and
experiment from there.

This configuration below will work with a forced user = use_name. Or
change the security mode to user and create accounts on the samba server for
the windows clients. Those accounts **HAVE** to mach the Window user and
password logons! Please read the comented sections.

Hope All This Helps and the Formatting Stays,

Not necessarily.  If the Linux files do not need to be accessed from 
the windows environment, you could create an image file, format the 
image as ext3, mount the image file as a loop device, and treat it as 
a standard ext3 mount point. 
Since this is only a movable copy of files from my /home/me directory 
structure, I can live with loosing the group and needing to reset it if 
moved back to a ext3 partition.


I will just have to work out the right rsync of cp command to do the 
bulk movement without all those warnings.  SHould only take reading a 
few man pages for that...


Again thanks.

[CentOS] recommendations/suggestions - geographically spread network based on Centos

2008-05-31 Thread dnk

Good day all,

I was wondering if I could pick some admin heads here as I have a HUGE  
project I have been tasked with.


I am asking here since I will be basing everything on Centos, and want  
it to all play nice together. If anyone feels this is straying off  
topic, please just reply off list. I do not want to be the cause of  
one of those threads.


I have 3 offices, 1 in Canada, 2 in Mexico. We are currently  
investigating connectivity options (still no results yet), but I  
suspect one of the mexican sites will be very limited.


I need to setup the typical office setup, but need to get the  
following figured out. I personally do not have experience in this  
type of network (all my past experience comes from a centralized  
office, one location, or a multi office with services all based in  
their respective locations).


So because The connectivity is probably limited (in our mexican  
offices), I will need to take that into consideration (obviously).
Our head office has a 10mb full duplex fiber feed, but we also have  
equipment in data centers.


What I need in the end is:

- exchange like functions IE Global address book, shared calenders,  
etc (looking at scalix, or could keep my existing email server - very  
happy with it, and just setup a LDAP server and a CalDAV server -  
still investigating this one though).
- Funambol with various connectors to push email and calendars to  
blackberries and iphones.

- vpn (openvpn) - mostly just the head office though
- collaborative / project management environment (looking at alfresco  
- sharepoint alternative)

- monitoring (nagios)
- helpdesk (glpi with ocs for inventory management)
- file sharing (samba)
- remote file backups (probably just rsync into a dedicated backup  
machine in a data center)
- access to all services (probably - still waiting back from the  
higher ups) from all locations


So my first thought is that my preference it to keep as much at a data  
center as possible due to security, temperature control, connection  
reliability, etc. Due to my inexperience with some of these products,  
(IE Scalix,etc) I am kind of wondering what the best way or topology  
is to do this is.


So at a brief first thought I kind of envisioned this:

- scalix,  Funambol, alfresco, nagios (also one in my office as  
backup), backup box collocated in the data center providing it can be  
locked down adequately, and still provide the needed services to all 3  
offices.

- in each office a samba file server, vpn server.

Due to the probable connectivity issue with the remote offices (one is  
literally in the desert at a work site), I did not think a constant  
inter-office VPN was the way to go, Or even securing the main data  
center services with VPN (unless I could build it right for speed).


However I guess I could lock down the data center services with VPN,  
and create a constant connection between head office and the data  
center, and allow the other offices to connect via individual vpn  
connections as needed.


Thoughts? Just looking for a general broad overview, or some software  
recommendations if anyone from experience has a recommendation that is  
possibly better than the software I had outlined here.


Dnk
