February 7, 20179 yr I'm new to unRAID, and doing some testing. I have 5 drive array (4 data, 1 parity). In the middle of copying data, I simulated a power loss by turning the unit off to see how it would handle recovery. After booting back up, I can see the data on the individual drives, but the the user share shows empty and gives a permission denied when attempting to write to it. unRAID is currently running a parity check. Is this normal behavior? Once the parity check finishes will the data re-appear on the share? Again I can look on the individual disks and see the data just fine.
February 7, 20179 yr Author I fixed it. The last directory being written was trashed on drive 2 - permissions were: d???. I started the array in maintenance mode, then ran "xfs_repair /dev/md2", restarted the array, and magic.
February 7, 20179 yr In the middle of copying data, I simulated a power loss by turning the unit off to see how it would handle recovery. Don't do that. Unraid isn't designed to have the rug pulled out from under it, you need a UPS to ensure that doesn't happen. It uses apcupsd to handle UPS communication, so any UPS that works with apcupsd should work with unraid.
