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

Fri Nov 30 16:07:54 CET 2007

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,

Pavel Hampl

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
.el5.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
(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
