February 23, 20233 yr Author Jsut to be clear, I didn't format the actual drives, I just set the filesystem on the missing drives to XFS, right?
February 23, 20233 yr Community Expert Correct. They still don't mount but it should let you check filesystem from webUI now since it knows what filesystem they should be. Check filesystem on disk5. Be sure to capture the output so you can post it.
February 23, 20233 yr Community Expert That's correct. The words check filesystem wherever it appears in the forum is a link to instructions.
February 23, 20233 yr Author restarted in maintenance mode. check filesystem for drive 5 gives me this output: Phase 1 - find and verify superblock... bad primary superblock - bad CRC in superblock !!! attempting to find secondary superblock... .found candidate secondary superblock... verified secondary superblock... would write modified primary superblock Primary superblock would have been modified. Cannot proceed further in no_modify mode. Exiting now.
February 23, 20233 yr Author Drive 5 and 6 don't show as emulated though. They just show as not installed. did I miss something somewhere?
February 23, 20233 yr Community Expert They are emulated and missing. Since you have dual parity, you can emulate 2 disks that are disabled or missing. And, it shows the emulated filesystems are unmountable. Also, mouseover the red x. 29 minutes ago, Deryg said: Cannot proceed further in no_modify mode. Check filesystem on disk5 again without -n. If it asks for it, also use -L. Post the output.
February 23, 20233 yr Author Here's the output. Let's pretend we don't see some of the more adult-oriented lost bit names Drive 5 disk check.txt
February 23, 20233 yr Community Expert Forgot to mention after New Config, disk7 (the other disk in this thread) is mounted and has 2.4T contents. So progress. Now, start array in Normal mode, still nothing assigned as disks 5, 6, and post new diagnostics
February 23, 20233 yr Community Expert Emulated disk5 mounted with 1.7T contents. Let's see how much in lost+found after repair. What do you get from command line with this? du -h -d 1 /mnt/disk5
February 23, 20233 yr Community Expert 20 minutes ago, Deryg said: everything is in lost and found? Looks like it. lost+found is things repair couldn't figure out. It often has some files it doesn't know the folders for, or files and folders it doesn't know the name for. lost+found is a user share just like all top level folders on array and pools. If you want to work with it over the network, you will have to configure that share to allow access. Install Dynamix File Manager plugin to examine and work with folders and files directly on the server. For files without their original names, Linux 'file' command may be able to tell you what kind of data is in a file so you can try to open it in the appropriate application.
February 23, 20233 yr Community Expert Let's see how things go for the other one. Check filesystem on emulated disk6. Be sure to capture the output so you can post it.
February 23, 20233 yr Community Expert Be sure to hang on to those original disks 5, 6 and don't change them in any way. Even though they are bad, there may be some things we can do to try to recover data from them too.
February 23, 20233 yr Author For disk 6 Phase 1 - find and verify superblock... bad primary superblock - bad CRC in superblock !!! attempting to find secondary superblock... .found candidate secondary superblock... verified secondary superblock... would write modified primary superblock Primary superblock would have been modified. Cannot proceed further in no_modify mode. Exiting now.

February 23, 20233 yr Community Expert Now, start array in Normal mode, still nothing assigned as disks 5, 6, and post new diagnostics
February 23, 20233 yr Community Expert Emulated disk6 mounted with 2T contents. Let's see how much in lost+found after repair. What do you get from command line with this? du -h -d 1 /mnt/disk6
