File restore error on LVMs
-
Hi Oliver. I am on the latest XO as i shown in the photo above.
-
I said "XOA" not XO from the sources
-
@olivierlambert I did notice the difference initially but XOA back up jobs are not available under 'XOA' so that's why i brought up XO.
-
You need to enable a trial and it will be available for 15 days
If your trial is already expired, just let me know your email in a direct message so I can extend it for the test. -
@olivierlambert
Thanks for the temp trial.The issue is still present on an updated XOA.
I add my Remote. Go to back up > file restore. I see my deltas there. I attempted to file restore and was greeted with the same message as the self-compiled version
-
@olivierlambert Ive created a support tunnel and sent you a DM of the id if you want to check out.
-
Okay thanks, we'll take a look
Let me ping @florent if he's available -

@Andrew
Thanks!
Watching that Issue now. -
@michmoor0725 the lvm parittion with one disk should work. Is it the case for you ?
-
@florent Still not working.
Here is the partition list for a standard Ubuntu 20.04.3 install.
Partition 3 is the main OS root as a single LVM (19G).
Trying to restore a file from it makes XO confused.xvda 202:0 0 20G 0 disk ├─xvda1 202:1 0 1M 0 part ├─xvda2 202:2 0 1G 0 part /boot └─xvda3 202:3 0 19G 0 part └─ubuntu--vg-ubuntu--lv 253:0 0 19G 0 lvm /

my test LVM VM works
@michmoor0725 or @Andrew , do you have any open tunnel I can use to test on your VM ?

@florent Yes i have a support tunnel IP.

I ran into this issue (xcp-ng 8.3.0 beta 2, XO 4cf03 ronivay docker image) and thought it had to do with my vm disk storage location (local vs NFS vs iSCSI). After not being able to restore on the file level from delta backups in all three situations I randomly decided to untick the "set up this disk as an LVM group" when installing a test vm which is enabled by default on Ubuntu 24.04 LTS.
The following screenshot is what the storage setup looks like with the default lvm group.
-
I'm a new ("about a week old") user of xcp-ng and Xen Orchestra and observed the same problem as described in this forum post.
The older (20.04.6 LTS) Linux installation I moved out of ESXi just for testing purposes is the one I'm testing on for now, but this problem seems to be easily reproduced on the newer versions as well (and I will test it within a few days).
From the backup I create, I can list the partitions in the backup, but am only able to select files from the boot partition (1.42GB), the two other shows the red exclamation mark.
The behaviour is the same with both XO from source and the just activated full trial of XOA (for testing the file-level restore).
Anyone solved this yet ?
-
@peo i am seeing the same issue on an Ubuntu 22.04 LTS VM setup with LVM.
-
@flakpyro What's the state of the LVM VG, its members and the LV? Has the VG been brought active along with its LV?
Is the VG and LV in the active system the file is being restored to the same as the one in the backup?
Are there any missing member disks (virtual) from the VM preventing the restore?
Are the relevant packages for the LVM software installed namely the following:-
- lvm2
- lvm2-dbusd
- lvm2-lockd

Here is the output of vgdisplay and lvdisplay from the VM being backed up.

The active system and backup should have the same exact layout. And no missing virtual disks.

Does the UUID from the backup match the one from the live machine?
Does the VG name matchup with backup and live machine?
-
@john-c Yep nothing has been renamed in regards to the LV or VG name inside the VM. I have not made any recent changes to this VM or the backup job itself.
I assume the UUID matches up as the VM is displayed by its name in the "VMs to backup" section of the backup job and not simply displayed as a UUID.
