This looks to be a ZFS problem, possibly due to bad storage layer (or
unreliable) or some kind of corruption of the core ZFS metadata.

Anyway, this is not an LXD problem and should not be worked on here.
This is strictly a problem somewhere within the storage subsystem (so
it could be related to Linux, or ZFS on Linux (kernel or userspace),
or ZFS userland tools). It may in fact not even be a code problem at
all, it may just be a legitimately broken FS or storage system. Hard
to say.
