@olivierlambert Yep cool, thanks for your help

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

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

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

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

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

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 Yep fair enough.

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

@olivierlambert Yep for sure, and your support here is so good it's not a huge problem, but I more feel bad bothering you with stupid questions more than anything haha

@olivierlambert

No worries:

1. Yep I'm using the community version. I've set it up via this script and keep it updated via this script.

2. I just ran the update script and am on 5.40.0, but I tried it with 5.35 before I updated and it didn't work (that's why I tried updating).

3. My VM's are stored on internal SSD's in raid

@olivierlambert Riiight, makes sense. I think part of my problem with XO errors is the cause of the problem isn't immediately apparent, you sort of have to pick through the traceback error messages. I'm sure it's not easy but it'd be great to have some instant feedback error popups for (what I assume is) common errors like this.

I get here and immediately get that exclamation mark and the below log error:

It seems to be just this VM, my others are OK...

Hmm, I tried in XCP-ng Center and that worked fine (though it did reboot the VM, which is fine). Do I need to shut down the VM IN XO before trying to change the RAM, or do I need to go into the advanced settings and adjust the dynamic etc settings first (didn't realise that was there initially)

I'm getting the following:
