RN214 Volume gone after upgrade from 6.9.1 to 6.9.2
Hi Forum Members, I need your help. yesterday I updated 2 of my 3 RN214 NAS to the new firmware 6.9.2. and the one I had a RAID volume on it, cant build its volume no longer. I got 4 RED drives in...
bastelspezi your volume is encrypted. Is the USB key with the encryption key connected? The volume can't be mounted without this.
yes of course. meanwhile I removed one of the harddrives just to see what would happen and it mounted the volume again. but obviously degraded. i backuped a few things off of it. and later installed a new harddrive in slot 4. then it resynced. it said it was successful, but the volume is messed up. I got now a lot of btrfs errors in the log files. it says the snapshots use 0GB of space but they are all there. but I cant delete them from the GUI. I think because the volume is apparently in read only. I also cant write onto it. I'm doing a scrub right now but i think thats making it all worse.
I have log files of every stage of the progress now.
I would really like to know how this all happend in the first place.

Do you have logs downloaded from closer to when the problem started?
It does look like there's some fs corruption.
Do you have a backup?
smart_history.log and disk_info.log show command timeouts on a few of your disks.
i've sent you the log file from right after the problem started (the one you have) I dont have anything from ealier since there was no problem.
i do have backup.
The timeouts showed up ever since I set up the system, didnt seem to affect anything. I posted about this issue 2years ago, I was referred to the compatability list. yikes. the timeouts seemed to not increase anymore once I had set the disk sleeptime to at least 45min.
thanks so much for your effort!
I realize the volume is pretty full.
I never did any scrubbing or defragmenting. I only ever did disk checks once a month
