Stuck on parity sync / data rebuild

Recommended Posts

Hey guys. My disk5 had an issue so I disconnected it, started/stopped the array, and then re-added it. I asked it to rebuild the drive but it has been stuck at 0.0% for 2 days and now my parity drive is red. I'm not really sure where to start now. My disk 5 has data that I would prefer not to lose but my main concern is really the remainder of my array being unprotected. I just ordered 2 more drives just in case. If someone would point me in the right direction, I would greatly appreciate the help. Thanks!

Parity disk dropped offline.  You probably disturbed the cabling to it.  Reseat all the cables to it and try again.

Would I take the array offline before messing with it. My dashboard says that mover is currently running so I don't know if I can force a spin down.

i popped out and re-seated my parity drive and rebooted my server. Now it has a warning "ALL DATA ON THIS DISK WILL BE ERASED WHEN ARRAY IS STARTED"

i am scared to do this because I don't understand how unraid could rebuild my parity when my disk5 is already being emulated. Any suggestions on how to avoid data loss would be much appreciated...

Assuming parity is still valid you can do this:

 

-Tools -> New Config -> Retain current configuration: All -> Apply
-check both "parity is already valid" and "maintenance mode" before starting the array
-start the array
-stop array, unassign disk5
-start array, check emulated disk mounts and contents look correct
-stop array, reassign disk5
-start array to begin rebuild

Whoa, I just followed your instructions through step 3 but my disk5 is now showing up as green... Do i need to disable/enable disk5 after all? Thanks so much for the help!

If you want to rebuild it yes, if you know for sure nothing was written to disk5 after is was disabled you can check and if everything looks OK leave it like it is and do a parity check instead, but you'll lose the option to rebuild it after that.

Perfect! This is an old archive drive that i know hasn't been touched in a long time. I will give that a go. Thanks for all the help. I truly appreciate it.
