Mokkisjeva Posted April 10, 2020 Share Posted April 10, 2020 Hellu, I just updated to 8.3 from 8.2 and after reboot I noticed that no dockers was running. After some looking around I then realized that the SSD cache disk was missing... I changed port on the SSD to see if I could still find it and it did. I then changed back to it's original port and it still shows up. So I have no idea what happened there, anyways now my cache driver is unassigned. How do I... get it back to how it was? I'm kinda sure all the dockers was installed on that disk 👀 So I'm kinda hoping I'm able to just "hey, this is the disk you used before, just continue like nothing happened" so I don't have to set up everything from scratch.

JorgeB Posted April 10, 2020 Share Posted April 10, 2020 If it was a single device cache just re-assign it. Quote Link to comment
Mokkisjeva Posted April 10, 2020 Author Share Posted April 10, 2020 (edited) I just did that, got the following: "Unmountable: Unsupported partition layout" So if I need to format the drive then I assume I lose the /appdata/ location completely? Something tells me the data is all ready lost Edited April 10, 2020 by Mokkisjeva Quote Link to comment
JorgeB Posted April 10, 2020 Share Posted April 10, 2020 Then something else happened, just updating/unassigning it wouldn't cause an invalid partition error, see if it mounts with UD, if yes backup then format on cache slot and restore the data. Quote Link to comment
Mokkisjeva Posted April 10, 2020 Author Share Posted April 10, 2020 Well shit, can't mount it via UD so rip. Any way I can prevent this from ever happening again? Like, is there backup solutions for dockers? Quote Link to comment
JorgeB Posted April 10, 2020 Share Posted April 10, 2020 Look for CA backup and restore. 1 Quote Link to comment
salcio Posted June 24, 2020 Share Posted June 24, 2020 So I have something similar I thing. I installed new raid controller and set it to hba mode (for now). After restart my cache drives are not assigned (but visible in unassigned devices) - data and parity disks were assigned correctly. Can I just assign disks to cache again. It was a cache pool with 4 drives. Quote Link to comment
JorgeB Posted June 24, 2020 Share Posted June 24, 2020 1 hour ago, salcio said: So I have something similar I thing. If they were unassigned after changing the controller the device identifications might have changed, if that's the only change you can re-assign them but only after starting the array without them so Unraid can forget the old pool config, then before re-starting the array you need to re-assign all the pool members and there can't be any "data on device will be deleted at array start" warning, but note that some RAID controllers make changes to the MBR and/or don't use the full partition size in which case the pool would might be unmountable.

salcio Posted June 24, 2020 Share Posted June 24, 2020 Do I need to assign them in any particular order ? or does it not matter ? Quote Link to comment
JorgeB Posted June 24, 2020 Share Posted June 24, 2020 Order doesn't matter, but all pool members must be present and assigned. Quote Link to comment
salcio Posted June 24, 2020 Share Posted June 24, 2020 Cool. Thank you very much. Quote Link to comment
