My problem is that when I call zpool list it gives this blank output....

NAME   SIZE  ALLOC   FREE    CAP  DEDUP  HEALTH  ALTROOT
-         -      -      -      -      -       -  -

However a zfs list shows that syspool is imported

NAME                     USED  AVAIL  REFER  MOUNTPOINT
syspool                 10.4G  4.15G  35.5K  legacy
syspool/.nza-reserve      31K  4.25G    31K  none

syspool/swap            1.03G  5.18G    16K  -
syspool/zvol             103M  4.25G    16K  -

also backed up by zpool status

  pool: syspool
 state: ONLINE
 scan: none requested
config:

        NAME        STATE     READ WRITE CKSUM
        syspool     ONLINE       0     0     0
          c1d0s0    ONLINE       0     0     0

errors: No known data errors

If I import a second pool and run a zpool list again...

NAME   SIZE  ALLOC   FREE    CAP  DEDUP  HEALTH  ALTROOT
-         -      -      -      -      -       -  -
-         -      -      -      -      -       -  -

This is causing problems in Nexentastor. NMV's create-dataset page will crash because it uses zpool list output to display current pools. Here is the error...

NZAObjectNotFound: ("Volume '-' does not exist"...

Has anyone experienced anything like this before?

Never seen this... Can you fill us in on the details of what happened before this? –  ewwhite Oct 18 '12 at 11:53

Problem was caused by the latest version of libzfs. I rolled back to previous version of the library which cured the issue.

Based on what? How did you end up with a bad version of libzfs? Where did you import the pool from? –  ewwhite Nov 19 '12 at 13:44
