night2you Posted January 12, 2016 Share Posted January 12, 2016 I needed more space so I was going to move the cache drive as part of my main array. I stopped the array and was going to move it from cache to the array. Then I realized there is still some data on there that I forgot to move. Unraid is saying it is unmounted and wants me to format it. I have *not* formatted it yet. Is there a way to get at the data on there? Link to comment

Unraid is saying it is unmounted and wants me to format it. I have *not* formatted it yet. Is there a way to get at the data on there? Did you actually assign it to a new slot in the array? Do you have a parity drive? Did it take a while before unRAID showed it as unformatted? Before a drive can be used in a new slot in a parity array it must be clear. This is so parity will remain valid. If you don't preclear it then unRAID will clear the drive. I wonder if it hasn't already done so. Link to comment
night2you Posted January 13, 2016 Author Share Posted January 13, 2016 Originally it was a Parity drive (sdd), Disk 1 (sdb), Disk 2 (sdc) and the cache drive (sde) I believe it did take a while before it showed unformated. Does that mean Unraid cleared it? I did not format or preclear the drive. Link to comment
trurl Posted January 13, 2016 Share Posted January 13, 2016 What filesystem was the drive originally? Click on the drive to go to its settings page and post a screenshot. Link to comment
night2you Posted January 13, 2016 Author Share Posted January 13, 2016 It says unmountable. Link to comment
trurl Posted January 13, 2016 Share Posted January 13, 2016 If you know what filesystem it should be, try stopping the array and set it to that and see if it is still unmountable. Link to comment
night2you Posted January 14, 2016 Author Share Posted January 14, 2016 I tried all three types and it still says unmountable. Would there be a way to mount it from the command prompt? Link to comment
trurl Posted January 14, 2016 Share Posted January 14, 2016 I think it may be cleared but you could try Check Disk Filesystems Link to comment
night2you Posted January 14, 2016 Author Share Posted January 14, 2016 So I went through this process: [*]Stop Array [*]Change filesystem type [*]run check per instuctions Riser and xfs it couldn't find the right superblock, for btrfs it wouldn't even let me scrub. Is there anything else I can try? Link to comment
trurl Posted January 14, 2016 Share Posted January 14, 2016 If it was cleared there is nothing you can do to get the data back. How large is the drive and how long did it take? Link to comment
night2you Posted January 14, 2016 Author Share Posted January 14, 2016 It's 1 TB. I don't remember how long. Would there be something in the syslog if it cleared it? Link to comment
trurl Posted January 15, 2016 Share Posted January 15, 2016 It's 1 TB. I don't remember how long. Would there be something in the syslog if it cleared it? Possibly if you haven't rebooted. Post it. Link to comment
night2you Posted January 15, 2016 Author Share Posted January 15, 2016 The diagnostics zip file is too large to post. The oldest zip file only goes back to the 12th, but even just zipping that file, it is larger than the forum would allow. There must have been a reboot at that point. Link to comment
trurl Posted January 15, 2016 Share Posted January 15, 2016 You can examine the syslog yourself, and see if you can find the timestamps that cover the period we are talking about and just zip and post that part. What exactly are you trying to recover from this drive? Link to comment
night2you Posted January 18, 2016 Author Share Posted January 18, 2016 This is most of the 12th, but I think it was after a reboot, so I'm not sure it has the relevant information. It's the oldest I have at this point. On my cache drive was a temp folder. I'm not even sure what was on it. It got put on the cache drive before moving to the main array. Thank you so much for sticking with this and trying to help me out! just12small.zip Link to comment
trurl Posted January 18, 2016 Share Posted January 18, 2016 That just says it can't find any filesystem. Looks like we will have to give up on this. Sounds like it wasn't important anyway. Link to comment
