ocg1003 partitions are severely misconfigured
Closed, ResolvedPublic


We just had an alert for disk space on ocg1003

08:51 <+icinga-wm> PROBLEM - Disk space on ocg1003 is CRITICAL: DISK CRITICAL - free space: / 1660 MB (3% inode=85%)

upon analysis, I found out that, on the contrary of what happens on ocg1002 where /dev/md2/ is mounted on /srv , it has no partition mounted under /srv.

It has, instead, a mostly empty LVM volume group.

We need to amend this situation and have a new partition on LVM mounted as /srv. It is challenging to do so without causing major service disruption, if we remember that ocg1001 is now under maintenance and depooled.
