sas disk faulted, how to receive notifications?

[openaspace]

Hi.
There is an easy way in proxmox to receive email notifications about the zfs raid pool errors?

...and in this situation what I can do to recheck the faulted disk?

Thank you.

Does your PVE is capable of writing mails? If so, please see here.

...and in this situation what I can do to recheck the faulted disk?

If you check the smart values (also via smartctl), a quick self test is also a good idea.
If everything looks OK to you, you can readd the disk, do a resilver and hope the error goes away.

Thank you!
I think was solved.. without the resilver.. I have detached two other disks on the same power cable .. probably is a slowdown for electric overload.

After the reboot I don't see any error

I can add 5th disk as spare in the mirrored striped pool to be used automatically if a disk fail?
