So I finally got my dual parity rebuilt and all was good.  All disks check out, all green.  Shut down server, connect another 8TB drive and bring up system so I can start pre-clearing it and now disk 4 in my array is disabled, contents emulated.  No smart errors, no nothing.  Just disabled.

 

Any idea what my have caused that?

I"m right int hat I can do a new config and select that the parity is valid (which I know it is since the array has not been started since the parity build completed) and it will avoid a parity rebuild?

Please post the diagnostics.

I already rebooted several times so I don't think I will have digs to help.  I created a new config and marked parity as valid and the array came online.  Now my problem is that I can't stop the array to add my new drives.  It gets stuck trying to mount /mnt/disk1.  I'm guessing this is a new problem with 6.12.

 

Forcing a reboot doesn't help.  The system restarts with the array down and I can't do a new config with the new drives because then the parity is most def not valid.  But if I start the array marking the parity as valid, then I can't stop it again.  *shrug*

 

 

Alright got it going.  I think what was happening is I was trying to stop the array too soon after starting.  Maybe this is new in 6.12 but starting too soon for me caused it not be able to shutdown.  I waited like 30 min after starting it and then stopped it, and it stopped ok.  Disk clear happening now.

Thanks!
