Can't delete ZFS pool. Pool is busy.

duarna · Jan 21st 2021

Hi, I am trying to delete a ZFS pool consisting of 2 drives in a mirrored configuration.

One of the drive died and has been removed so it is in a degraded state. I have removed the SMB shares and shared folders referencing to it.

When I try to delete the pool via the GUI, I get the following error.

I suppose there is a process I need to kill, but I am not sure how to do, could I get a hint?

Code

OMV\ExecException: Failed to execute command 'export PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin; export LANG=C.UTF-8; zpool destroy "MediaPool" 2>&1' with exit code '1': cannot destroy 'MediaPool': pool is busy in /usr/share/php/openmediavault/system/process.inc:182

You need to remove all SMB shares and Shared Folders and other services that are still attached to the pool.
