I had a failure on a 300GB SAS Drive in my array of 9 x 300GB SAS drives, 4 x 3TB WD Reds, 4 x 4TB Wd reds and 2x 6tb wd reds for parity

I replaced the drive with another 300GB Sas drive but when I select the new drive the page refreshes but the drive isn't selected anymore

 

I tried doing a new config; the wd reds get readded fine and ready to start the array but all 9 of the 300gb sas drives can't be added; after the page refreshes the drive goes back to unassigned

 

HELP GUYS!!

Have you tried this?

That solved it thank you!

 

Any help on how to keep parity to rebuild the replaced drive after I did a new config?

Check the Parity is valid box - but why did you do a New Config? If you're simply replacing a disk you just need to assign the new one to the slot previously occupied by the failed disk, then start the array and the rebuild then begins.

You shouldn't have done a new config with a disable disk, but if you didn't start the array yet it may still be possible to recover that disk, do the following:

 

-new config, assign all disks (including new 300GB disk), looks like you have dual parity so order of all disks has to be maintained as it was before

-check both "parity is already valid" and "maintenance mode" before starting the array

-start the array

-stop array, unassign disk to rebuild

-start array, check emulated disk mounts and contents look OK

-stop array, reassign disk

-start array to begin rebuild

Done

Thanks a lot!! great help

any hdd errors?

Don't see any disk errors, but looks like you didn't follow the instructions and did a correcting parity check instead, so there were a lot of sync errors and it's not possible to rebuild the missing disk anymore.

It was an empty drive

 

Btw the last 4TB wd red never gets any data on it

Any idea why? I have all discs selected in Global share settings

If shares are set to highwater it will once disk16 gets to under 2TB free.

Oh ok

 

Thanks a lot! love the help!

BTW should I run another parity check when this one is done?

It always good to make sure there are no sync errors.

Thanks a lot!!!!
