DjSamLb Posted January 28, 2017 Share Posted January 28, 2017 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!!

John_M Posted January 28, 2017 Share Posted January 28, 2017 Have you tried this? Quote Link to comment
DjSamLb Posted January 28, 2017 Author Share Posted January 28, 2017 That solved it thank you! Any help on how to keep parity to rebuild the replaced drive after I did a new config? Quote Link to comment
John_M Posted January 28, 2017 Share Posted January 28, 2017 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. Quote Link to comment
JorgeB Posted January 28, 2017 Share Posted January 28, 2017 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 Quote Link to comment

DjSamLb Posted January 29, 2017 Author Share Posted January 29, 2017 any hdd errors? tower-diagnostics-20170129-0349.zip Quote Link to comment
JorgeB Posted January 29, 2017 Share Posted January 29, 2017 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. Quote Link to comment
DjSamLb Posted January 29, 2017 Author Share Posted January 29, 2017 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 Quote Link to comment
JorgeB Posted January 29, 2017 Share Posted January 29, 2017 If shares are set to highwater it will once disk16 gets to under 2TB free. Quote Link to comment
DjSamLb Posted January 29, 2017 Author Share Posted January 29, 2017 Oh ok Thanks a lot! love the help! BTW should I run another parity check when this one is done? Quote Link to comment
JorgeB Posted January 29, 2017 Share Posted January 29, 2017 It always good to make sure there are no sync errors. Quote Link to comment
