I was trying to figure out the cause of high IO Delay on my server and found the function fio to test the drive. It worked great as I found the cause of the IO delay was the drive was only functioning at 6 IOPS. After a quick reboot, my VM storage was missing. Apparently, fio wiped the drive and only left it with the data from the test. I have a backup that is a couple days old, so I'm not in complete panic mode, but does anyone know how to recover and data from the drive? it was a zfs pool of a single drive.
