Hello,

 

I just installed new ram into my system and everything went terribly wrong. I foolishly set up xmp profile (just had one option 3600mhz) and when Unraid booted it behaved really bad. The log started showing xfs corruption errors and I freaked out, I pressed the shutdown button but it wouldn't work, so after a few minutes I did an unclean shutdown.

 

I put the bios back to defaults and rebooted. But now the second parity drive and Disk 10 won't mount.
Unraid gave me the option to format disks but I chose the "check" one. Now it's reading the drives and would like to know how to proceed. As I understand it it'll do the check operation and then I'm going to have to rebuild disk 10 and then the second parity?

I attached both syslogs, one when the corruption was happening and a recent one.

Both disks are disabled, but disk10 is mounting according to diags, if contents look correct you can re-enable both disks at the same time.

 

P.S. both DIMMs are installed in the same channel, for best performance and stability use different channels.

Ok, how can I enable them? Do I stop the array take out the drive and let it rebuild with just 1 parity disk? And then do the same with the second parity?

Is there any way of doing it preserving the data that's already in there?

 

Thanks!

If the emulated disk is mounting and data looks correct you can rebuild on top and it will preserve the data, and you can do both disks at the same time:

 

stop array

unassign both disks

start array

stop array

re-assign both disks

start array to begin data rebuild and parity sync.
