[hobbit] Hobbit server doesn't start on CentOS 5 with hobbit-4.2.0 installed

Fri Nov 30 16:49:02 CET 2007

I looked at that already and it seemed high.  Mine is also:
kernel.shmmax = 4294967295

I found the problem though:
max number of segments = 4096
segments allocated 4096

Fixed with:
sysctl -w kernel.shmmni=8192
kernel.shmmni = 8192

Thanks for making me look at ipcs again though.

FTR my Hobbit server:

-> sysctl -a|grep shmmax
kernel.shmmax = 4294967295

Hi,

What about to increase shmmax in the system when it complains that cannot
get allocated new 262kB?
You can check what is your size: # sysctl -a|grep shmmax
This cmd says you what is already used: # ipcs -m

You can increase it in /etc/sysctl (just put there something big, it is just
a restriction, kernel.shmmax = XXXX)  and then apply it by : # sysctl -p

Cheers,

I uninstalled hobbit-4.2.0-7.el5.re.i386.rpm and compiled hobbit-4.2.0 from
source with the allinone.patch and get exactly the same error.

It might be worth noting that this was originally a minimum CentOS 5 install
- I had to install gcc-c++ (and rrd-devel and pcre-devel) to compile hobbit,
and I previously had to install gcc for compiling some other software - all
from yum.

The server has 2 GB of RAM but is running several other services.

Any other ideas?

Sebastian

Just compile it from source.  If you don't know how to do that I can give
you instructions command by command, just ask.  I use CentOS5 on my boxes
but I've never bothered with the RPM.

I installed an RPM of hobbit-4.2.0 called hobbit-4.2.0-7.el5.re.i386.rpm,
which I probably got from here: 

<http://rpm.razorsedge.org/centos-5/RE/repodata/repoview/hobbit-4-4.2.0-7.el
5.re.html>
http://rpm.razorsedge.org/centos-5/RE/repodata/repoview/hobbit-4-4.2.0-7.el5
.re.html 
It includes the All-in-one patch.  So I configured the cfg files and started
hobbit, but I get this in hobbitlaunch.log:

2007-11-29 17:33:47 Task hobbitd terminated, status 1 

This is the first time I've started it, so I presume that this is normal:
"Cannot access checkpoint file /usr/libexec/hobbit/server/tmp/hobbitd.chk
for restore".  The problem looks like this:  "Could not get shm of size
262144: No space left on device".  I see that there are two similar issues
listed on  <http://www.hswn.dk/hobbit/help/known-issues.html>
http://www.hswn.dk/hobbit/help/known-issues.html that relate to FreeBSD, but
none of the sysctl keys listed are in this version of Linux:

# cat /proc/version 
Linux version 2.6.18-8.1.15.el5.centos.plus (
<mailto:mockbuild at builder6.centos.org> mockbuild at builder6.centos.org ) (gcc
version 4.1.1 20070105 (Red Hat 4.1.1-52)) #1 SMP Thu Oct 25 06:49:40 EDT
2007

Google returns 1 result for "Could not get shm of size" "No space left on
device" and that was the Known Issues page I've already checked.  Any ideas?

Also, I noticed that the hobbitd.pid file did not get deleted when hobbitd
terminated.  It seems like it should have been.

Many thanks, 

Sebastian
