Where is the "WARNING YOU LOST A DRIVE" message?

[axrusar]

I intentionally removed a physical hard drive from a small test regular desktop PC server setup with Proxmox, RAID1 ZFS pool to simulate a hardware failure and other
tests i am running here.

I was expecting the system to show any warning messages from the boot process... or as soon as i open the proxmox web gui, something indicative like a flashing red banner with a warning or something but no. the system is working just as if nothing happened, which is great of course, but if i do not get a warning (from a very stationary backup file server where no one ever logs in to the proxmox gui in this case), the server would keep running with just a single drive....

Yes if i go to the ZFS section i see this:

But i prefer something a little more obvious, like an email alert, computer beeping or smoke signals... anything...
Where can i set options for this?
Thank you

And obviously your host needs to be configured to be able to send mails.

Best is also do have external monitoring (for everything you have in your infrastructure including the monitoring system itself).
