[Fedora-directory-users] fds fails to start in centos 5.3 openvz instance

[Anthony Giggins]

Hi Guys,

After installing fds on Centos 5.3 in an OpenVZ virtual instance from
the Enterprise Linux 5 instructions provided
http://directory.fedoraproject.org/wiki/Download
I'm getting the errors below in the logs when starting the service.


[04/May/2009:02:33:21 -0400] - Fedora-Directory/1.2.0 B2009.091.197
starting up
[04/May/2009:02:33:21 -0400] - Failed to create semaphore for stats file
(/var/run/dirsrv/slapd-sso.stats). Error 38.(Function not implemented)


I'm pretty sure this is going to be a OpenVZ issue but I thought I'd
post here first to get idea what is actually failing so I can
investigate the OpenVZ side of things, any information that can help me
troubleshoot this issue would be great.

Thank You

Anthony

Does /var/run/dirsrv exist?  Is it writable by your directory server user?

Yep that folder exists, permissions look fine

drwxrwxrwx  3 root   nobody 4096 May  4 02:33 dirsrv

Do you have the nsslapd-rundir attribute in cn=config in 
/etc/dirsrv/slapd-yourinstance/dse.ldif?

Yep, that looks good

nsslapd-rundir: /var/run/dirsrv

Try starting the setver in debug mode
/usr/lib/dirsrv/slapd-instance/start-slapd -d 1

Nope that doesn't work but as it's a 64bit virtual instance the command
below seems to work

/usr/lib64/dirsrv/slapd-sso/start-slapd -d 1 

Appears to work up until

[05/May/2009:20:04:33 -0400] - add_created_attrs
[05/May/2009:20:04:33 -0400] - => send_ldap_result 0::
[05/May/2009:20:04:33 -0400] - <= send_ldap_result

Are you attempting to run in a VM or in some sort of chroot 
environment?  I've seen this before when running the directory server in 
a chroot.  This is what I had to do:
echo tmpfs /dev/shm tmpfs defaults 0 0 >> /etc/fstab
mount /dev/shm
run the server

If you are using a chroot (e.g. mock) you must do the mount /dev/shm in 
the same chroot "session" - it does not persist.

Thanks Rich

This fixed the issue.
