Hello,
we setup an CEPH Storage and want to move all VMs from the NFS Storage to the CEPH Storage - but after i moved a 265G VM to the CEPH Storage i was very surprised, the Image has now 265G and not ~10GB.
We use qcow2 Format on the NFS Share and i moved the Image over PVE to the CEPH Storage, so there are no way to select an other format than raw. I test multiple Commands e.g. resize with shrink, flatten etc. but nothing helped about this. But if i restore an VM to the CEPH, then i see this in the Log "space reduction due to 4K zero bocks 1.99%".
How can we Sparse the raw File on CEPH? We need to do this Online or a minimun Downtime.
We have 1TB Space on each node and currently all VMs use around 370GB - so there is enough Space to grow, but only if we not lose thin Provisioning.
Thanks!
