Error exporting/disconnecting pool.

[Vincent Jansen]

Hello,
I had a failed pool with multiple degraded disks. I removed them all and replaced them. Now I like to remove the old pool and I get:

Error exporting/disconnecting pool.

This is a pretty fresh install.
Ive read the other posts on the subject. I removed all jails. Al the disks are wiped. No clue why it doesn't want to remove the pool.
Can someone help me?
