Hmm, I’m getting:
[root@shl1 lxd]# lxc export git-http git-http.tgz -vvv
Error: Create backup: Backup storage: Could not create snapshot LV named snapshot--05236fd3--6b5f--4499--b074--7ae20cfb9d88
The reason I’m trying to backup containers is because I’m in the below situation. My sense is the above error might be related?..
Do you this I should reboot the host to recover state?
Many thanks,
Simon
Yes try a reboot
The above error persists after a reboot 
Thanks for your helps so far - any advice on diagnosing further?
Kind regards,
Simon
Is the container running when you run lxc export?
Yes it was.
Try stopping it and doing export as that might skip the snapshot.
Alas, it appears to want to snapshot when STOPPED too…
Can you create a new storage pool of dir type and then copy the instance to it locally, then try exporting it from there.
[root@shl1 lxd-export]~ lxc export git-http-bak git-http-bak.tgz
Backup exported successfully!
Fab, thanks so much!!
Nearly there! I can export the smaller ones, but even when exporting to a different partition lxd wants to consume space on the root partition which is nearly full. Is there some way to only use the target partition?
Many thanks,
Simon
Just found this!
Thanks Thomas,
I’m getting
[root@shl1 sw206]# lxc config set storage.backups_volume pool2/storage
Error: cannot set 'storage.backups_volume' to 'pool2/storage': unknown key
I’m on LXD 3.6 - was this config on a different key back then?
Many thanks,
Simon
Ah you cannot upgrade from 3.x to 5.x (only from 4.x), as 3.x is very old.
You could try upgrading the 3.x host to 4.x and then exporting and reimporting.
Sorry I should have thought of that earlier.
Can you provide the contents of the backup.yaml file in the exported tarball file, it may be easier to just manually modify that file.
Apologies, I’m not following. My problem is the root partition runs out of disk space on export. The container in question is only 7.5G and there’s 15G free space, however it still runs out.
It seems storage.backups_volume isn’t an option in 3.6 - is it safe to update to v4.x whilst containers are running?
Many thanks,
I personally wouldn’t, especially as we know its going to alter the instance’s config.
(Apologies this is dragging on!)
I get Error: Create backup: Backup storage: exit status 1 from the export command, I’m fairly sure there’s enough spare disk space…
Should I shutdown all containers and upgrade to 4.x?
Kind regards,
Yes I think thats the best approach, either that or get some more disk space
