February 17, 20179 yr My server crashed when I tried to reboot whilst it was doing a parity check. After switching off and on it won't load unRAID properly (get to login, but it won't load console and my disks aren't showing under mnt) saying: waiting for /dev/disk/by-label/UNRAID (will check for 30 sec) I've checked the USB and it appears fine. Has anyone come across this before? is it easy to fix? thanks in advance
February 17, 20179 yr Community Expert The message means it is looking for the disk labeled UNRAID. What exactly do you mean by I've checked the USB and it appears fine.
February 17, 20179 yr Author The message means it is looking for the disk labeled UNRAID. What exactly do you mean by I've checked the USB and it appears fine. That I can access it on a W10 machine to browse. The disk pulls up the boot menu (GUI, safe, memtest etc) so why does it dissapear when booting? I'm reading lots of posts on the forum but none seem to give a clear answer/resolution.

February 17, 20179 yr Author I went for the nuclear option as I do an overnight backup of my files. I formatted the drive and added the default files from LT, and it booted ok. But, I'm stumped as to how to access my backup as it's on my array. Do I just add all my drives (does the order matter as the backup when restored will put them in the right order?) except the parity drive, copy the backup to another machine, restore and then reboot?

Do I just add all my drives (does the order matter as the backup when restored will put them in the right order?) except the parity drive, copy the backup to another machine, restore and then reboot? If you assign all of drives as data drives, one of them will be unformatted. That will be your parity drive. Do not leave it assigned as a data drive or it will be formatted when you start the array. (unRAID is not concerned with drive order unless you have dual parity. In that case, if you change the drive assignment order, then Parity 1 will be correct and Parity 2 will be incorrect.) Once you get everything working again, you should make a copy of your flash drive and have it stored in some place outside of the array. You can do this by stopping the array and copying the entire contents of the flash drive to a folder on another computer.

I've rejigged my backup method to have my personal files off the array - I definitely need to rejig my VM, appdata and flash backups to be off the array as well. UPDATE: I'm in! Thanks everyone. Love how even when things go wrong, unRAID is recoverable.
