Unable to display files in File Restore (failed to setup loop device)

[simonk83]

@olivierlambert Yep fair enough.

It's only that one VM so I guess it's that, I'll have a dig around.

[simonk83]

Sorry, quick question just because it'll probably save me hours of googling

The log says

failed to setup loop device for /dev/debian-vg/root

If I run lsblk -fs in the VM I get:

 lsblk -fs

So is it that XO is trying to mount /dev/debian-vg/root but it's actually /dev/debian--vg/root ??

EDIT: Nope, never mind:

simon@dashboard:/dev/debian-vg$ ls
root  swap_1

Hmm.

EDIT2: If I run the same command in the VM I get:

simon@dashboard:/$ sudo mount --options=loop,ro --source=/dev/debian-vg/root --target=/tmp/tmp-751rBsQbj6YN1TI
mount: mount point /tmp/tmp-751rBsQbj6YN1TI does not exist

So is XO failing to create that first? I guess not as the error would probably indicate such

[olivierlambert]

You other VMs also have LVM with a "--" in the LV name?

[simonk83]

@olivierlambert One does, but that seems fine with the file restore...

[olivierlambert]

To rule out a environment issue, you can try to same restore with XOA. If you have the issue too, it means there is a bug in XO. Otherwise, it's your install

[simonk83]

@olivierlambert Well... I was just typing out a response about how I can select the smaller partition called Linux just fine but not the bigger partition called root, but when I clicked on root this time it loaded just fine....

Can't really explain that. I did reboot the VM again a bit ago, but I tried it straight after that and it still didn't work. Now a couple of hours later with no changes at my end it's fine. Odd!

[olivierlambert]

Okay, well We don't have a known issue with that on our support so I suppose it was "env" related

[simonk83]

@olivierlambert said in Unable to display files in File Restore (failed to setup loop device):

Aaaand now it's broken again haha. I'll try what you said and give it a go in XOA when I get a chance, see if it's the same there.

[olivierlambert]

Okay, let us know. You can use the trial to unlock all features for 15 days, which is enough to test this

[simonk83]

@olivierlambert Ohh I think I've already used it actually. I'll boot up the VM and check.

[olivierlambert]

Let me know I can re-extend it

[simonk83]

@olivierlambert Ah thanks, it has indeed expired. Is there any issue having both XO's running at the same time by the way?

[olivierlambert]

No problem I'll extend your trial

[olivierlambert]

Extended!

[simonk83]

@olivierlambert Thanks for that. Well it seems fine in the main XO so I guess it's a problem with the community version, or at least my install of it (plus something to do with that single VM). Who maintains the community version?

[olivierlambert]

There is no "maintenance" but community support if you follow how it's installed from our official documentation: https://xen-orchestra.com/docs/from_the_sources.html

If you use something else (like a 3rd party script), then create an issue on the GH repo where you found the script

[simonk83]

@olivierlambert Yep cool, thanks for your help
