I have btrfs drives. I was getting loads of errors in my second pool drive. It's probably smoked.

 

Stopped array, unassigned second pool drive. Started array, whoops! I forgot to move the Cache Drives from 2 down to 1. Stopped array, Cache drive from 2 to 1. Now when I start array, I'm getting Unmountable: Unsupported or no file system.

 

I went to re-add the old drive, and it said adding this drive will be formatted, all data will be lost on there. Dang it. Oh thank God, the backup system (Settings > Backup/Restore App Data) /mnt/user/backup/unraid/appdata-backup/ab_20231106_030004  <whew>!!!

 

I need to get app_data back to run all the services etc. thanks!

 

 

tried these steps ( 2018 limetech post )

stop array

unassign cache drive

start array

stop array

reassign cache drive

start array.

Still unmountable.

You can't do that, and should not even be able to do it since the GUI doesn't allow that.

 

Post the output of

btrfs fi show

 

Thanks for getting back @JorgeB

I ended up formatting, un-assigning, re-assigning, and reformatting my primary cache nvme01 drive. I restored from backup (make sure that CA Backup is working y’all!)

 

my SWAG custom Network didn’t stick through it, and I had to restore all Docker Apps individually. But their templates with my old settings and their appdata was there. Whew!

 

Thanks again

If you reformatted it doesn't really matter now, or do you still need help with something?

does Fix Common Problems check that that CA Backup is running somewhat regularly? It should. 
 

Patient was lobotomized so I guess that’s that. Thank you very much for your help @JorgeB
