Can't disconnect old volume

[henderbc]

I'm unable to disconnect or export an old volume that is no longer being used. The volume is(was) on a single striped disc (ada2) which is installed, but the status of the volume is shown as UNKNOWN (see below)

When I try to Export/Disconnect the pool, I get:

If I try #zpool export volume4, I get cannot open 'volume4': no such pool

Any ideas? I don't need this volume and I don't care what happens to the content of the disk.

 

[Samuel Tai]

Try zpool destroy -f volume4.

 

[henderbc]

root@FREENAS2[/]# zpool destroy -f volume4
cannot open 'volume4': no such pool

 

[Samuel Tai]

What about zpool export -f volume4?

 

[henderbc]

root@FREENAS2[/]# zpool export -f volume4
cannot open 'volume4': no such pool

 

[Samuel Tai]

What does zpool status -v show?

It seems that volume4 has an dangling entry in a database somewhere, and the drive that used to be volume4 (ada2) is present, but zpool doesn't know how to get rid of the volume4 entry.

Is "volume3" your pool or is it "volume4" .
Is this a typo?

 

[henderbc]

Nope, not a typo.
-ada0 is my boot drive
-ada1 (volume3) holds data
-ada2 (volume4) is the drive (volume) no longer in use and the one I am trying to get rid of.

 

[Samuel Tai]

Try a quick wipe of ada2, which clears the partition table, and then a reboot.

 

[henderbc]

How do I "run a wipe" of ada2?

 

[Samuel Tai]

Under Storage->Disks, expand the unused disk. There should be a Wipe button.
