I want to import a zpool from a freebsd-zfs partition that is backed by a
zfs volume. Is this possible? The sequence of commands that result in
success are eluding me.
gpart show:
=> 40 33554352 zvol/zroot/vol GPT (16G)
40 1024 1 freebsd-boot (512K)
1064 984 - free - (492K)
2048 2097152 2 freebsd-swap (1.0G)
2099200 31453184 3 freebsd-zfs (15G)
33552384 2008 - free - (1.0M)
zfs list (relevant parts):
... zroot datasets ...
zroot/vol 16.5G 367G 672M -
I've tried 'zpool import' which produces no results, also tried explicitly
with the -d option. The results of this command lead me to believe that the
pool from the zfs volume is not being exported.
I tried using 'zfs mount zroot/vol', failed with: operation not applicable
to datasets of this type.
The zfs volume is the backer for a VM, this is what I'm trying to acheive:
1) shutdown the VM
2) import zpool from the VM
3) make changes to the VM zfs datasets
4) export the zpool
5) re-boot the VM.
Anyone point me in the direction of enlightenment?
