I'm testing OMV with ZFS on one of my virtual machines.
I set up reporting in OVM and check the ZFS ZED box.
Running OMV: 4.1.5-1
openmediavailt-zfs 4.0.2-1
Testing the scenario when one drive fails.
Code
Start situation:
root@openmediavault-testing:/etc# zpool status
pool: TANK
state: ONLINE
scan: none requested
config:
NAME STATE READ WRITE CKSUM
TANK ONLINE 0 0 0

Now I set one drive offline:
Code
root@openmediavault-testing:/etc# zpool offline TANK ata-VMware_Virtual_SATA_Hard_Drive_01000000000000000001
This results in a degraded Zpool:
Code
root@openmediavault-testing:/etc# zpool status
pool: TANK
state: DEGRADED
status: One or more devices has been taken offline by the administrator.
Sufficient replicas exist for the pool to continue functioning in a
degraded state.
action: Online the device using 'zpool online' or replace the device with
'zpool replace'.
scan: none requested
config:

Now I don't get any notification by email, or in the GUI that there is anything wrong with my device.
This does not look like expected behaviour to me.
