[SOLVED] Parity Drive Say's Disabled check for assistance


Recommended Posts

Hi all,

 

I have a machine which had duel parity 1x4TB and 1x3TB WD Reds.

 

Over the last couple of days I decided to replace the 3TB with  a 4TB ....

Stopped the array, swapped the drives, got the attention message that ALL data will be removed.

After I rebooted the machine every thing came back on line...... but noticed the red cross marker on the

original 4TB drive.

 

I was directed to the forum to get assistance "Parity Device Is Disabled, Device is disabled, contents emulated"

 

Help! please ....

 

Sorry forgot the diagnostics !!!

Since we're missing the pre-reboot diags we can't see what happened, but SMART for parity looks fine, couple of CRC errors so you should replace the SATA cable to rule it out and then rebuild to the same disk, to do that:

 

-stop the array

-unassign parity

-start the array

-stop the array

-reassgin parity

-start the array to begin the parity sync

 

If it happens again grab the diags before rebooting.

 

PS: three more disks have UDMA_CRC errors, these may or not be old, you should monitor them for a couple of weeks, any increase replace the SATA cable.

Good Morning from the UK

 

The parity check finished this morning and seems OK !! mm

I'll watch for any more UDMA_CRC errors as you suggested ...

 

Attached are the latest sys/dia files.

 

thanks again

Thanks for this, kinda weird how you have to do this to "undisable" a parity disk. Thought there would be "rebuild" array without having to remove and add devices.
