Thanks, I can confirm that Nagios also reports free space to be normal now. We can close the case.

I’ve created a new 300GB disk on storage01-data1 and used it to extend the volume.

Also, disks of the old templates01 VM were migrated to storage01 as well in order to free up some space on storage02.

As discussed on the meeting, the storage02-data1 storage domain doesn’t seem to have free space for extension so instead let’s create a new volume on storage01-data1 and attach it to the VM


Alternatively, let’s move away some VMs to clear up space and keep the whole FS on a single physical storage.

Let’s extend pv3 to 600G:
