January 12, 20233 yr UG. I had 2 drive become unmountable within the array. I have 2 parity drive so i was hopeful. I shut it down and added the 2 new drive in their place as you do when swapping out bad drives. the rebuild was going until a third drive became unmountable. parity sync finished but now a third drive was bad and Errors piled up. This became an error chasing issues as drive after drive became unmountable. i repeated this. Now the array is half the size it was the remainder of the drive sit in my unassigned device table. I have mounted one at a time used kursider or dolphin to copy the unassigned data back to the array. this will not work directly for some reason /mnt/user/ has some permission issues or something input output errors i get. so i created a recovery folder to drop the files into in order to get them back into my array. I can move some files from this recovery folder to the respective share folders but not all and not all at once. some random folder will not allow me to write folder into them. I cant mkdr, cp or mv . i have chmod 777, +rwx etc. but all i get are I/O errors. Please help root@Prime:/# chmod ugo+rwx /mnt/user/Media/ chmod: changing permissions of '/mnt/user/Media/': Input/output error
January 12, 20233 yr Community Expert Wish you had asked for help before doing anything. Rebuild won't fix unmountable. How do you know any disks were bad? Bad connections are much more common than bad disks, and bad connections are often caused when changing disks or otherwise messing around inside the case. Attach Diagnostics to your NEXT post in this thread.
January 12, 20233 yr Author Diag's from 1 week ago and today. I know some disks are bad due to SMART checks calling out failures. At lest 2 of the lot are unmountable in unassigned slots, both of which contain Smart Errors. Either i have the worst luck or its something else. I have swapped Cards and cables and even whole back plains prior to this latest failure. when i was getting other comms issues. I tried to repair the missing superblock via your forums but it would not fix the drives. so i pulled them out of the array config and started a new parity. Im concerned that parity will not work thought its at 75% now rebuild. Disk 5 was reading for the first few hours but has posted errors. It would be great to determine how to get my files to merge back into the folders. I have had some luck but for some reason part of my media folder user group is root and not nobody. prime-smart-20230102-16001.12.23.zip prime-smart-20230102-16001.2.23.zip Edited January 12, 20233 yr by donuts13 added more info

January 12, 20233 yr Author odd mb it did not extract correctly here is a new file the smart folder contains 23 disk report. Hope this helps. prime-diagnostics-20230112-1347.zip
January 12, 20233 yr Community Expert Unfortunately, you filled logspace some time ago so can't see what happened after that. I think we should concentrate on getting your array stable again with valid parity, then we can work on trying to get data from those unassigned disks. I'm still trying to make sense of these latest diagnostics you posted, but I see now that one of those files you attached earlier that was labeled smart actually contained diagnostics. Judging from syslog in that one, it is the same as these latest diagnostics you attached. You mentioned you have diagnostics from a week ago. Can you try again to post those?
January 12, 20233 yr Community Expert All of the array data disks in your screenshot mounted, disk7 has little if any data. Is that expected? 7 hours ago, donuts13 said: Im concerned that parity will not work thought its at 75% now rebuild. Disk 5 was reading for the first few hours but has posted errors. Yes, that isn't going to be good. Might as well cancel it and we can try again. Rather than try to examine SMART for all of your many disks, can you tell me which have SMART warnings?
January 13, 20233 yr Community Expert If parity rebuild hasn't completed, cancel it, shutdown, check connections on disk5. Then reboot so we can start fresh with a clear log, and post new diagnostics. 48 minutes ago, trurl said: Rather than try to examine SMART for all of your many disks, can you tell me which have SMART warnings?
January 13, 20233 yr Community Expert Might as well disable Docker in Settings for now until everything is stable again.
January 14, 20233 yr Author My array is rather large so Sync takes about 1 day... well at this size it does. I still have ~50TB to add back. This time sync looks good. I also ran New Permissions with appdata, excluded. Diag attached. Now i just need a clan way to Mount the unassigned drive and merge back the folders to the correct array shares. prime-diagnostics-20230114-0315.zip
January 14, 20233 yr Community Expert 1 hour ago, donuts13 said: array is rather large so Sync takes about 1 day Only depends on size of largest parity, not number of disks, unless you have controller bottlenecks (port multipliers). Haven't finished studying these latest diagnostics yet. You can help with that On 1/12/2023 at 6:21 PM, trurl said: Rather than try to examine SMART for all of your many disks, can you tell me which have SMART warnings?

Will any of the unassigned mount with Unassigned Devices plugin?
January 14, 20233 yr Author Solution the array as it is, is put together with what drive that are ok. Th below image is where most of my files are. Dev 2,3,5,7 have errors. Dev 2,3,5 will not mount. Dev7 i still functional and im copying to the array right now what i have on this drive. The Fix permision tool worked and im able to write to the normal share folders from these unassigned drive. At this point i think im mostly ok... with the exception of the 3 disks that either don't have a file system or will not mount. I have zero hope of getting the data off those drive unless you have any ideas. It will take two or three weeks copying at ~60MB/s to the array from all of these unassigned drive.
January 14, 20233 yr Community Expert 16 minutes ago, donuts13 said: will not mount Are these supposed to be xfs disks? You can check filesystem on Unassigned Devices. Be sure to capture the output so you can post it.
January 15, 20233 yr Author These are the 3 drive that started this mess... Should I click the run with correct flags? In the past the xfs repair has not worked but this seems different. Outputs: Dev 2: smart check attached FS: xfs Executing file system check: /sbin/xfs_repair -n /dev/sdk1 2>&1 Phase 1 - find and verify superblock... xfs_repair: read failed: Invalid argument xfs_repair: data size check failed xfs_repair: cannot repair this filesystem.

January 15, 20233 yr Community Expert Are you sure these were XFS disks? I notice a RAID controller in your system. RAID not recommended for many reasons. Are these disks plugged in to that controller? Were they plugged in to that controller?
January 15, 20233 yr Author they are all xfs formatted drive as unraid does. I have two controllers one i did a special FW mod per the Unraid forums to allow for SW RAID. It supports 8 drives. The other card was needed for the expansion and it loaded the drives with no issues. It supports 16 drives. In general i can Physicaly move a HDD between the Drive bays of the two cards and it will detect and mount with no issues.
January 15, 20233 yr Community Expert I'm just wondering if the unmountable unassigned disks were previously on a RAID controller and now aren't, or vice versa. Thinking this might be why they are unmountable.
January 15, 20233 yr Author No they were never part of a HW RAID via a controller. Those drives sat on my array for over 2 years. The 16 drive controller (Microsemi Adaptec HBA 1000-16i 12Gbps PCIe Gen3 SAS/SATA) right now is supporting everything within the array currently, plus a few "unassigned drives" i would have to power down the box and catalog each position to match them up vis SN. When I first started this build I did a FW mod on the two 8 drive controllers so that unraid would even detect drives attached to it. I have since exceeded 16 drive and upgraded to a larger Case to support more drive. One of the original controllers is still there and i added this new 16 drive controller about 6 months ago. I do know that im pushing the limits of PCI lanes for this build (assuming i fill all drive bays) and would not be able to add any further devices.
January 15, 20233 yr Community Expert 1 hour ago, donuts13 said: never part of a HW RAID Not exactly what I was asking about. People sometimes try to use RAID controllers with Unraid by making each disk a separate RAID0 volume.
