While I was away for work, I got a SMART email warning saying it could not open one of the drives in my ZFS array on my file server. I have a daily email set up for disk status, and the drive was just gone. It wasn't in the array, or in /dev, and was missing from the daily run report with SMART status.
I ordered a replacement, replaced the "missing" drive, resilvered, and everything looks fine. I popped the "failed" drive in my eSATA dock on my desktop, and the drive seems to work just fine. Should there be anything in particular I should be looking at on the server itself to get an indication of why the drive disappeared? Last night my Seagate external USB drive also dropped off, but the power supply for it is squealing so I think maybe it just lost power... but it is a similar issue, so I don't want to overlook a larger issue.
The drive that dropped is currently doing a WD diagnostic long test, but it already passed the short test. I guess if it tests find, I'll reinstall it in the array, and find out I bought a new 4TB drive for nothing.
