Description of problem:
vdsm service fails to start (reasonable) when no space left on disk, however, it alerts nothing about it, and when i start service, it says 'ok', however, whet querying for service status it appears down.
the problem is that no space left on disk, hence, I suggest to add a test to service when it starts.
this issue found on rhel6, however, i suppose it exists in previous versions.
this is important, as when it occurs, log cannot be written, so, no actual info why service doesn't start.
make sure no space left on root partition, and start vdsm
verified, tried to start vdsm service with no success, and got the following message: low space [FAILED]
root@silver-vdse ~]# service vdsmd status
VDS daemon is not running
[root@silver-vdse ~]# service vdsmd start
Server address not specified in /etc/sysconfig/netconsole
vdsm: low log space [FAILED]
