Thank you for your reply. Here is the relevant output:
# gpart show
=> 63 31277169 ada0 MBR (15G)
63 1 - free - (512B)
64 31277160 1 freebsd [active] (15G)
31277224 8 - free - (4.0K)
=> 0 31277160 ada0s1 BSD (15G)
0 4194304 1 freebsd-zfs (2.0G)
4194304 4194304 2 freebsd-swap (2.0G)
8388608 22888544 4 freebsd-zfs (11G)
31277152 8 - free -
...
So, it looks like ada0s1a is a ZFS VDEV. That explains why mount is
complaining.
Trying another approach:
# zpool list
no pools available
# zpool import
pool: bootpool
id: <redacted>
state: ONLINE
action: The pool can be imported using its name or numeric identifier.
config:
bootpool ONLINE
ada0s1a ONLINE
# zpool import bootpool
cannot mount '/bootpool': failed to create mountpoint
# zpool status
pool: bootpool
state: ONLINE
scan: none requested
config:
NAME STATE READ WRITE CKSUM
bootpool ONLINE 0 0 0
ada0s1a ONLINE 0 0 0
errors: No known data errors
# find / -name bootpool
<nothing>
Exporting and attempting to import under /tmp produces similar results:
# zpool export bootpool
# zpool list
no pools available
# zpool import -R /tmp bootpool
cannot mount '/tmp/bootpool': failed to create mountpoint
# zpool status
pool: bootpool
state: ONLINE
scan: none requested
config:
NAME STATE READ WRITE CKSUM
bootpool ONLINE 0 0 0
ada0s1a ONLINE 0 0 0
errors: No known data errors
# find / -name bootpool
<nothing>
How do I import and mount bootpool?
