Problem with file level restore from delta backup from LVM parition
-
Hello, any news on that ?
-
We don't have other reports of failed restore on LVM, so it slipped out of the radar.
Ideally, a support ticket might be better to keep it in the TODO

Hi
I have the same issue.

Hope it helps. -
XFS? That might be the reason why, I don't remember that we support XFS for file level restore.

@badrAZ or someone else of XO team will try to reproduce the issue. They are under heavy lot for a bunch of new exciting features, so it might take time to test.

I tested this functionality on
ext4andxfsand it works for me.
Unfortunately, i need to reproduce this issue in our lab to be able to investigate more.
-
Same problem with XOA @othmar ?
-
I did not have a XOA i have the xo-server 5.54.0 community edition on ubunto server.
-
@othmar Install XOA in trial mode and then retest to see if the issue is present with it.
-
@Danp
yes it's the same on XOA in trial mode latest patched. -
It's same here. Problem is in community version and in xoa trial.
-
There's obviously something different between the VMs you use and ours for tests. Would you be able to provide a VM export so we can deploy it on our side, backup it and see why file restore doesn't work?
-
I am seeing the same issue with LVM restores. Exists between Trial and Community editions.

Do you have a VG using multiple PVs?
-
That one does not. I assumed that was the case for another one that had the issue, and working to move the VMs to VHDs that are not on LVM.
