Umountable cache drive recovery

[01max]

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.

NVMe device failed:

 

SMART overall-health self-assessment test result: FAILED!
- available spare has fallen below threshold
- media has been placed in read only mode

 

You may still be able to mount the pool read only following the FAQ instruction and copy the data, but don't forget to specify the partition in the end, it must be /dev/nvme1n1p1

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.

You need to decrypt the device first, if you do that with the array stated, it will show unmountable, but it should be decrypted.

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 !
