qmrestore: Rounding up size to full physical extent

[zzjp]

I have this observation, every time I restore with qmrestore, it says

Rounding up size to full physical extent...
​

Which it does. So between every backup and every restore, it uses up an extra LVM PE. Ok, the VM still boots and runs... but why burn up a PE?

Better question is what is it doing to the filesystem, especially the Windows VM with NTFS?

Can I just reduce the LV to the original size with no ill effect to the VM?


This is a dual cluster with DRBD and the following:

pve-manager: 1.5-10 (pve-manager/1.5/4822)
running kernel: 2.6.32-2-pve
proxmox-ve-2.6.32: 1.5-7
pve-kernel-2.6.32-2-pve: 2.6.32-7
qemu-server: 1.1-16
pve-firmware: 1.0-5
libpve-storage-perl: 1.0-13
vncterm: 0.9-2
vzctl: 3.0.23-1pve11
vzdump: 1.2-5
vzprocps: 2.0.11-1dso2
vzquota: 3.0.11-1
pve-qemu-kvm: 0.12.4-1
ksm-control-daemon: 1.0-3

Yes, that should work.

After reducing the LV back to original size, and checking filesystems, it does work. Many thanks.

Hey, thanks for figuring this out. Just makes Proxmox easier to use.
