hi guys,
i have an issue here
suddenly one of my container can not running after restart …

when i start it give me an error
sudo lxc start netbeat
error: no such file or directory
Try lxc info --show-log netbeat for more info

the log give me information
"Failed to mount ZFS dataset “pool1/containers/netbeat” onto "/var/lib/lxd/storage-pools/pool1/containers/netbeat\

when i try to import it
sudo zpool import pool1
cannot import ‘pool1’: no such pool available

sudo zpool list

any idea how to fix it ??

LXD remembers pool1 as having been a loop device (/dev/loop1) which is a very very unusual setup for ZFS as ZFS has its own loop system for file based pools…

Anyway, this suggests that this particular zpool is backed by some file, not by a partition.
If you locate that file, you should be able to import the pool by using zpool import pool1 -d /path/to/directory

Hi stephen, Thanks for your clue about .img file … already found the file and import it …
everything get back to normal …

Thank You Stephen
