trurl Posted August 2, 2019 Share Posted August 2, 2019 Are you sure these disks weren't already unmountable before your other disk was disabled? Did they have any data on them? How long have you been working with this server? Can you think of anything else you can tell us about how you got to this point? Quote Link to comment
JoshHolme Posted August 2, 2019 Author Share Posted August 2, 2019 I’ve had the server for a couple of years and swapped disks out as they’ve died or if I wanted to upgrade them to a higher capacity without any issues. Then as I was uploading some blue ray rips to it recently I got an email that one of the disks was in an error state. I didn’t notice if the drives were unmountable right then, but after I figured out which disk died I rearranged my disk to match the number of the disk with the number in the drive bay. After this I noticed they were unmountable. Is my data basically gone at this point? Quote Link to comment
JonathanM Posted August 3, 2019 Share Posted August 3, 2019 Do you have either diagnostics, a status email, or a screenshot of the main gui from before all this started? Quote Link to comment

JoshHolme Posted August 3, 2019 Author Share Posted August 3, 2019 @johnnie.black After letting it run overnight on disk 2 (the disk with the I/0 beyond EOF, I get this at the end of the output verified secondary superblock... would write modified primary superblock Primary superblock would have been modified. Cannot proceed further in no_modify mode. Exiting now. Should I continue without no_modify mode? Or do you think that it would not be successful? Also, where should I input: fdisk -l /dev/sd2 Quote Link to comment
trurl Posted August 3, 2019 Share Posted August 3, 2019 1 hour ago, JoshHolme said: Also, where should I input: fdisk -l /dev/sd2 Nowhere. 2 is not a valid substitution for X. Figure out which device letter is currently assigned to the disk number. In your earlier screenshot, disk2 was sdb, for example, but you should always confirm before using /dev/sdX since that can change if you make any disk changes, or even if you just reboot.

JoshHolme Posted August 3, 2019 Author Share Posted August 3, 2019 Oh okay, I mistakenly read that as replace X with the correct number for that disk. What does this command do exactly? And I’m assuming I don’t put this in the correct filesystem tab of the disk since I have to specify which disk to execute it on, so where do I put it? Also, should I do this over the filesystem correction without no-modify mode? Quote Link to comment

At the command line. You can open a session to the command line by clicking on the command line icon (>_) in the top bar of the webUI. The command lists the partitions on the disk.

JoshHolme Posted August 3, 2019 Author Share Posted August 3, 2019 I don’t know if I’m just oblivious (completely possible) but I don’t seen the company line option here that you’re talking about in the top bar. Quote Link to comment
trurl Posted August 3, 2019 Share Posted August 3, 2019 Didn't realize you were running such very old version of Unraid. Possibly that is even involved in your attempts at checking filesystems. I know there have been updates in that area recently. A bit of a catch-22 since you may need to upgrade to repair the filesystems, but upgrading might add its own complications. To enter the command, you would have to login to the command line at an attached monitor and keyboard, or login with telnet or ssh from another computer on your network. Quote Link to comment

trurl Posted August 3, 2019 Share Posted August 3, 2019 I'm not sure if that's correct or not. Probably is, but I don't have any disks in my server that small to compare it to. Try it on one of your 4TB disks (not parity). Quote Link to comment

trurl Posted August 3, 2019 Share Posted August 3, 2019 That is the same as my 4TB. Not sure what else I can add at this point. Let's wait and see if @johnnie.black has any thoughts about your old version of xfs_repair. Quote Link to comment
JoshHolme Posted August 5, 2019 Author Share Posted August 5, 2019 (edited) @johnnie.black Here are the results of my xfs_repair status on the three corrupt drives. As @trurl pointed out, I'm running an older version of unraid (v2017.05.26). I don't want to upgrade it to prevent causing potentially more issues with more variables. Should I run these checks without the -n to allow changes, or do you have other suggestions/things I should do instead. I have about 9 TB of movies that I've been ripping over the past 4 years (did not have a proper backup solution up until this point but you can be sure I will after this is either resolved or my data is unfortunately lost), and I want the best chance of recovering the data.

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. Thanks in advance for your help, I really appreciate it! Edited August 5, 2019 by JoshHolme Quote Link to comment
JorgeB Posted August 5, 2019 Share Posted August 5, 2019 5 hours ago, JoshHolme said: Should I run these checks without the -n to allow changes, or do you have other suggestions/things I should do instead. This is a very strange problem, can't see how what you did could cause this, even if it was an unclean shutdown, try running xfs_repair without -n, if you want clone the disk to a new one an try on that one first.

itimpi Posted August 5, 2019 Share Posted August 5, 2019 Stop/restart the array and see if the disk now mounts and it looks like the data is intact. Check for a 'lost+found' folder as that is where any files whose name could ton be determined is put by the repair process. Quote Link to comment
JoshHolme Posted August 5, 2019 Author Share Posted August 5, 2019 (edited) All disks are now mountable and all data seems to be there! Thank so @itimpi, @johnnie.black, and @trurl for all the help. You saved me 9 TB of data amassed over the past 4 years. I'm forever grateful 👍 Edited August 5, 2019 by JoshHolme Quote Link to comment
