[[Plugin] CA Appdata Backup / Restore v2]

I just want to say thank you so much for making this plugin. I unexpectedly lost all the data on my cache drive earlier today but luckily I had this installed, so while I lost some very critical data I didn't have to waste a whole lot of time manually setting up all my containers again. It was just a matter of pressing restore and everything was back minus today's changes. 

 

Thank you!!!

[Encrypted cache drive "Unmountable: Volume not encrypted"]

Thanks for getting back to me! 

 

To be honest, I had a massive time constraint so I ended up just sacrificing the data and I'll have to rebuild 😭

 

Luckily there was nothing personal in there, it was just hours and hours of work that I'll have to redo.

 

That was one of the many things I tried before erasing the cache drive, I got:

Device /dev/nvme0n1p1 is not a valid LUKS device.

I also couldn't recover the partition using fsck, btrfs check or xfs_repair. I even had a look using parted and apart from having a size assigned there were no further details. I even tried physically swapping the drives back to their original locations but unsurprisingly all that did was swap the physical device names. I also tried mounting it using unassigned devices as well to no avail, and a lot of other things that I can't recall.

 

I'm confident there was something simple I've missed, so if there was please let me know in case I or others encounter this again 🙂

[Encrypted cache drive "Unmountable: Volume not encrypted"]

Hey everyone,

 

Two days ago I added my first cache drive to my server, a brand new 1tb Samsung 970 EVO Plus. I had a bit of trouble initially getting it to format which I think was Safari related, but I eventually managed to get it to format as XFS - Encrypted. Or at least that's what I told it to do. Once encrypted, after at least one restart I realised it was showing "btrfs" as the filesystem.

 

I restarted several times without issue, having to re-enter the password to start the array each time, and it just continued to show "btrfs". It was definitely encrypted, because the Shares page reflected it. Sadly at this point I moved quite a few important files onto the drive as I assumed it was safe to do so.

 

Then today I swapped the NVME slots for my two SSDs. The other SSD mounts normally, but when I attempt to mount my new cache drive it shows "Unmountable: Volume not encrypted", which I've noticed it does this regardless of what password I enter. If I switch the filesystem manually to any of the non-encrypted options or Auto it shows "Unmountable: No file system".

I've also attached the logs if anyone could please help me to either get it to mount or recover my data?

 

Thank in advance for any assistance :)
