Lxc import - Error: not found (part 2)

LXD
1

Hello, I’m having the same problem as described in this prior message from 2020. It appears to have been fixed [1], [2] so I don’t know why it’s happening for me.

Details:

I have two workstations each running NixOS 21.04 and lxd 4.1.4. Both are ZFS filesystem, both with lxd pool named lxdpool and the zfs pool being rpool/safe/lxd. Same network adapter, albeit differently named in each system. Almost identical setups.

I ran lxc export comic-oriole comic-oriole.tar.gz on one machine, rsync’d it over to the other, and tried running lxc import comic-oriole.tar.gz. But got the error:

> lxc import comic-oriole.tar.gz                                             
Error: not found

I also ran lxc import comic-oriole.tar.gz --debug, but it’s still not clear exactly what isn’t being found.

Any ideas or suggestions?

Can you paste the contents of the backup/index.yaml and backup/container/backup.yaml here from inside the exported tarball please?

Sure, thanks.

Update, when trying to create a new instance I get another error, probably related:

> sudo lxc launch ubuntu:21.04                                                    
Creating the instance
Error: Failed instance creation: No storage pool found. Please create a new storage pool

Hmmm, the lxd pool I created using lxd init is not there (lxdpool), even though it appears in the config files above:

> sudo lxc storage list

But the ZFS pool exists, that was also created during lxd init:

> zfs list|grep lxd

No profiles either:

Seems somehow lxc init created the ZFS pools, but not everything else it was supposed to.

Update: I uninstalled and purged lxd/lxc and deleted the ZFS dataset, then did a fresh install and fresh lxd init.

That fixed the problem. I was able to successfully lxc import and start the other workstation’s exported container, as well as create a new container with lxc launch.

I think part of what happened the first time was that I initially ran lxc init --preseed preseed.from.other.workstation.txt. That seemed to work, but apparently not. After hitting the errors above, I tried running lxd init, but that gave errors too. Uninstalling and reinstalling fixed it all.
