why didn't i get any alert ?
how can i include this kind of error to get an email ?
Do you have notifications configured and working in OMV? If yes, do you have the zfs zed notification enabled?
I wasn't asking about the zed service. I was talking about OMV level notifications:
no i don't have this option.
You must not have the zfs plugin installed then?
Can you post a screenshot of the notification page? Even on OMV 6.x, it should be there.
sure, here it is.
The page to show is System-> Notifications-> Events
What you are showing is the widgets from the Dashboard
sure, here it is.
Those are dashboard widgets not the Notification tab.
Do you have Notifications setup in the Notifications -> Settings tab?
fwiw, this install was via omv-regen, a couple of months ago.
In case it helps, the salt modules that omv-regen updates after installing the zfs plugin are:
zfszed collectd fstab monit quota nfs samba sharedfolders systemd tftpd-hpa
In that order.
And the notifications are regenerated later, in phase 5, when the zfs plugin has already been installed and the existing pools have been imported.
I've never had any problems with it in all the testing I've done and a lot of people use it. I don't think omv-regen is causing this.
what is the output of: cat /etc/zfs/zed.d/zed.rc
tdriver et al
Trying this out in a VM seems to indicate ZFS "statechange" event emails my not be created when you might expect. See this old thread too: Degraded ZFS not notifications
So far I found the default OMV behaviour to be as tdriver described when disk drops out of a ZFS pool.
TEST PROCEDURE
=================
0. Setup notifications ( used dummy email) and checked ZED events
1. Create a new ZFS mirror pool in a OMV VM.
2. Live remove scsi type disk from VM.
3. Check zpool status
root@omv7vm:/# zpool status Xpool
pool: Xpool
state: DEGRADED
status: One or more devices are faulted in response to persistent errors.
Sufficient replicas exist for the pool to continue functioning in a
degraded state.
action: Replace the faulted device, or use 'zpool clear' to mark the device
repaired.
scan: scrub repaired 0B in 00:00:15 with 0 errors on Wed Feb 28 16:41:32 2024
