ash.881 Posted May 26, 2017 Share Posted May 26, 2017 (edited) Hi guys, I'm in a bit of trouble and need some assistance. Last night my parity drive was suddenly redballed - I suspect due to a faulty sata cable. Tonight I had just installed a freshly precleared disk in a different slot (with a different cable) and started a parity rebuild. Part way through the rebuild another one of my drives has been redballed due to disk read errors, this drive has now had it's cable replaced and is detected (but still redballed) however I think during the cable swap I have accidentally bumped the new parity drive is now listed as missing. In short I currently have one data drive redballed and a parity drive that's only partially rebuilt but now listed as missing. I have not written anything to the array since before parity died last night so there should be no reason why the data on the redballed drive would be damaged. Can I pull the parity disk, force unraid to enable the redballed data disk to get the array all green and then install a precleared disk to do a parity rebuild somehow? I'm running version 5.0.5 Thanks in advance for any assistance. Edited May 27, 2017 by ash.881 Issue Solved Quote Link to comment
JorgeB Posted May 26, 2017 Share Posted May 26, 2017 -Take a screenshot of current array main page -Utils -> New Config -assign all disks, double check parity is the parity slot or don't assign parity for now -start array (parity sync will begin if parity is assigned) Quote Link to comment
ash.881 Posted May 26, 2017 Author Share Posted May 26, 2017 Brilliant, thanks mate, I thought that might have been the procedure but wasn't game to give it a go without asking first. I'll pull parity, reset the config and then look at re-adding a parity drive once it's all green. Quote Link to comment

Drive cages are strongly recommend to avoid this problem. They allow you to add or swap disks without opening the case. Quote Link to comment
