I have moved the zpool image file to an OpenSolaris machine running 101b.
r...@opensolaris:~# uname -a
SunOS opensolaris 5.11 snv_101b i86pc i386 i86pc Solaris
Here I am able to attempt an import of the pool and at least the OS does not
panic.
r...@opensolaris:~# zpool import -d /mnt
pool: zones
id: 17407806223688303760
state: ONLINE
status: The pool is formatted using an older on-disk version.
action: The pool can be imported using its name or numeric identifier, though
some features will not be available without an explicit 'zpool upgrade'.
config:
zones ONLINE
/mnt/zpool.zones ONLINE
But it hangs forever when I actually attempt the import.
r...@opensolaris:~# zpool import -d /mnt -f zones
<never returns>
The thread associated with the import is stuck on txg_wait_synced.

There is a corresponding thread stuck on zio_wait.

I see from another discussion on zfs-discuss that Victor Latushkin helped Erik
Gulliksson recover from a similar situation by using a specially patched zfs
module. Would it be possible for me to get that same module?
