Noob trying to rebuild after lost drive

Featured Replies

Didn't have much luck trying with the old google search so here i am. I started a mission to move over to a supermicro 45 JBOD i wasn't using for anything. Then i though while I'm at it i could update some hardware (mobo and cpu) too while I'm at it. Everything moved over fine for the hardware. Unraid USB was locked in write protect mode. Ok get a new drive made from the back up and off we go. Start up the array and one of my drives seems to have failed. Damn, so i got a new drive and attempt to rebuild the array. Gets about 20 to 30 gigs into rebuild and errors out. drive checked out fine when in a different machine. swapped to a different bay in the JBOD and unassigned, power cycle, and try again and got same thing. Tried to pull the cable and HBA from other working system still has the same happen. So I'm not sure if its the JBOD here or something from the move.

You rebooted before getting diagnostics, can't see what happened before boot. Is it the same drive each time?

You have a lot of drives, so if you could help us narrow it down by specifying which is the problem. I do see a couple of unassigned disks that might have been assigned disks until they disconnected.

 

So many drives also makes me suspect power.

Disk28 and Parity2?

  • Author

WDC_WUH721818AL_3WKELYVK is the drive that's my problem disk 28 yes

  • Author

The parity two i was trying to start to upgrade my parity to my newer larger drives i picked up to put in, but now im dealing with the loss of disk 28 on the array. Even pre clear fails. Ill try to mount again and pull a new log.

Unclear. Did you have 2 parity drives?

  • Community Expert

unassigned sdag 26TB FJMY would be large enough for parity or parity2

  • Author

no just one drive for parity before.

  • Author

SMART for that disk looks OK and it isn't very old. It has never had an extended SMART self-test though.

How is this drive powered? Do you have a backplane?

These usually mean a power/connection issue, or weak PSU.

  • Author

yeah its on a back plane. i moved the drive to other empty spots and it was still doing the same. Tried moving one of the other working drives to the spot i had that drive in and the working drive showed up and ran like normal.

  • Author

trying to swap out psu now

  • Author

But did it work with all the other disks spunup? Rebuild requires access of all disks simultaneously.

  • Author

all other disk have been working fine and spin up fine. data on the parity is emulated so array is working. just anything new i put into any spot is not working. 

  • Community Expert

So you have already tried a different disk and a different slot?

  • Author
  • Solution

yep, ended up going back to the old 36 bay and its rebuilding fine now. Guessing its my expander on the backplane
