Wrong FS type #14

Closed kevin39 closed 5 years ago

kevin39 commented 5 years ago

Hi, Not sure why but my 1st backup after applying the patch failed.

This is strange.

I added this selftest command to ensure that this does work properly. This is what I receive:

./pve-5.3-9-diff-backup-addon selftest-lxc
Proxmox VE 5.3-9 - differential backup support, v3
Kamil Trzcinski, http://ayufan.eu/, ayufan@ayufan.eu

This is destructive command that requires:

- the CT501 present
- and CT511 empty

Press enter to continue, Ctrl-C to abort

It seems to succeed.

ayufan commented 5 years ago

Are you sure that this works before applying patches, as it seems to me that the layout of disks slightly different, thus why it fails.

kevin39 commented 5 years ago

No. Sorry maybe it wasn't clear.

It's the first time I'm using your patch. My server are still runing 4.4 (the patch has been applied without any error). When the backup occurs yesterday, it shown my this error.

kevin39 commented 5 years ago

Do you have a fix ?

ayufan commented 5 years ago

I don't think that this is bug of pve-diff-backup. Did you try if you can backup and restore without patches applied?

kevin39 commented 5 years ago

My bad. I think I found the problem, I sheduled a backup for this night. I'll be back to you tomorrow.

kevin39 commented 5 years ago

Sorry, it was my fault. I've a corrupted image and by mistake I used this one to try the diff-backup. I tried on another LXC container and it works fine :)

Thank you
