rcmpayne Posted June 27, 2017 Share Posted June 27, 2017 I have had two drives fail on unraid and just added two 3TB WD RED but after assigning them, i cant start the array "invalid config" Disk 3 shows missing bad 1TB. Replacing with 3TB red Disk 4 shows unassigned. Replacing with 3TB red Any ideas how i can get these two new drives assigned? Quote Link to comment
JorgeB Posted June 27, 2017 Share Posted June 27, 2017 Do you have dual parity? You can't replace 2 disks at the same time with single parity. Quote Link to comment
trurl Posted June 27, 2017 Share Posted June 27, 2017 Maybe this is what you meant, but you don't want to ADD disks, you want to REPLACE them. Unless you have 2 parity disks you can't rebuild 2 failed disks. Go to Tools - Diagnostics and post the complete diagnostics zip. Quote Link to comment
rcmpayne Posted June 27, 2017 Author Share Posted June 27, 2017 (edited) I am running a second pre-clear on my new drives again as i thought that was the issue. Attaching a screenshot. I only have one parity drive so if i lost data its ok i guess. How do i get these new drives in? Edited June 27, 2017 by rcmpayne Quote Link to comment
JorgeB Posted June 27, 2017 Share Posted June 27, 2017 You'll lose all data on disks 3 and 4: Tools -> New config -> Retain all Then assign new disks3 and 4 and start array to begin parity sync. Quote Link to comment
Frank1940 Posted June 27, 2017 Share Posted June 27, 2017 (edited) There is a possibility that you might be able to recover some of the files from these disks. Remove the disks and set them aside for now. Get the array running with your replacement disks. Then install the unassigned devices plugin. See if you can mount either of these disks with that plugin. (You might want to install the disks in a external USB drive case.) If so, then see if you can recover any files from these two disk.

rcmpayne Posted June 27, 2017 Author Share Posted June 27, 2017 Ok will give that a go now. The new drives are formatting in xfs but all others are in riserfs. Is this ok? Seems like xfs is the perfered method. Quote Link to comment

I think it is quite likely that we could have gotten your system back to just one disk that could have been rebuilt from parity. Probably if you would just put the original disks back in and post your diagnostics we could have a better idea of what your options are. Quote Link to comment

If you have already done New Config then its too late to go back. Quote Link to comment

You must let unRAID format them after they have been added to the array. If you haven't done New Config then put your array back like it was, with the original disks, and without the new disks. It might even let you start it like that depending on exactly what you meant by "failed". Then post a diagnostic. Quote Link to comment

IF you are going to try this, if you get a prompt about formatting any of these disks, DON'T do it without further instructions!!!! Quote Link to comment
rcmpayne Posted June 29, 2017 Author Share Posted June 29, 2017 Ok all back and working. I added the bad drives back but the array would not start so I used the add-on to mount them separately out side the array and all my data was available. So I added the new red drives and did killed the parity. Everything is working now and just moving data from the bad drives back to the array using cp -v -rThanks everyone.

trurl Posted June 29, 2017 Share Posted June 29, 2017 Possibly nothing actually wrong with those drives. Problems caused by connections, cables, controllers are much more common than bad drives. Without a diagnostic we can't say. Quote Link to comment

The drives have power on house in the 6 year range and smart report shows lots of errors with them. Sure it's time to retire them. Sent from my SM-G920I using Tapatalk Quote Link to comment
