Pbs restore VM to small disk

[frankz]

Hello everyone, I wanted to know if it is possible to restore a vm on a slightly smaller disk. The original disk is 320 GB the current one of 260 . The data of the original are at 50% so theoretically there would be space .

no. see https://pve.proxmox.com/wiki/Resize_disks (and that only applies *after* restoring)

Thank you for responding, but it seems that I can only expand but not decrease. I should copy a 300g vdisk on a 270 . The data is few is the volume that is large ...

If the storage is thin and the virtual disk inside the backup is not full, then maybe it will work. Shrinking a virtual disk is tricky as many threads on the forum will show you.

Thank you for answering . It is thin. I'm trying with a live distro and I try to run a lvresize --resizefs -L 30G /dev/ubuntu...... We'll see

yeah, shrinking is dangerous, and thus something you need to do manually.

Thanks Fabian, but I solved it differently. I created a new VM and restored the app backup. Anyway thank you
