That did it ! I was able to get my appdata back thanks to you @JorgeB you saved me hours / days of painful (re)config. I sent you some beer money for your trouble ! Here are the exact command I had to use to mount the drive if some poor souls get into the same situation as me : cryptsetup luksOpen /dev/nvme1n1p1 temp_cache mkdir /mnt/temp_cache mount -o rescue=all,ro /dev/mapper/temp_cache /mnt/temp_cache/ Thanks again !

Thank you so much for your answer ! > SMART overall-health self-assessment test result: FAILED! Replacement it is then. Thanks To mount, as indicated in the FAQ thread, I tried : ~# mount -o rescue=all,ro /dev/nvme1n1p1 /temp mount: /temp: unknown filesystem type 'crypto_LUKS'. dmesg(1) may have more information after failed mount system call. So I guess I'm stuck there, or is there a way to do that even with the encryption ? I don't find anything solid online and I definitely don't want to do anything stupid that would worsen my chances of getting my data back, so sorry if it's a stupid question.

Hello, I am having issues with my cache drive since last night. When I woke up this morning, Docker containers were down and after a reboot my cache is now flagged as Unmountable I was directed to this comment by Fix commons problem and have tried the three proposed solutions including btrfs check --repair And all I am getting are in the like of : Starting repair. Opening filesystem to check... No valid Btrfs found on /dev/nvme1n1 ERROR: cannot open file system I'm pretty sure I already know I'm dead and the only solution would be to format (or even replace long term), but I'm also a sad tired clown with not so great habits on the backup side of things in the past few months, and I would very much love to be able to get my appdata back. george-diagnostics-20240522-1210.zip Edit : English is not my first language, sorry if I wasn't explaining myself correctly
