Failed to start LXD - main daemon. ZFS storage pool "default" could not be imported: cannot import 'default': I/O error

Hi all, my lxc container can’t start normally, when I check the lxd.service , it shows like that:

when i use “zpool import -F default” to fix it, the system shows that “no such pool availabel”, after input the zpool status in command line, the result is “no such pool availabel”, too.

problem is solved
run

sudo zpool import -d /var/lib/lxd/disks/ default -F

in command line
the “default” is the name of pool
and /var/lib/lxd/disks/ is the path while pool(default.img) exists
