Hi,

 

Today I noticed I couldn´t access one of my shares and whent into GUI and found my Cache disk states "Unmountable: No file system".

On this disk is a share with alot of important documents. I thought I had managed to relocate the share to a specific disk and had removed the "Use cache disk", but the Move command did obviously not work

 

To make everything worse I haven´t set up my backup server yet and all the disks from my former NAS are wiped thoroughly... (me stupid)!

 

I´m new to unRAID and recently installed it (~1.5 month ago), the former NAS was a Xpnology.

 

I searched and tried to follow this FAQ

 

But I´m not able to mount the disk, the command "mount /dev/sdf1 /mnt/disk4/restore" reports:

mount: /mnt/disk4/restore: can't read superblock on /dev/sdf1

 

And if I try "btrfs restore -v /dev/sdf1 /mnt/disk4/restore" it reports:

Error searching -1

 

The scrub command doesn´t work:

ERROR: '/dev/sdf1' is not a mounted btrfs device

 

I have also tried the --repair, so I guess I´m FUBAR. But using the command "btrfs fi show /dev/sdf1" it reports:

Label: none  uuid: 714e018c-6066-41b5-ac47-9568092cab56
        Total devices 1 FS bytes used 49.30GiB
        devid    1 size 232.89GiB used 56.02GiB path /dev/sdf1

 

I really hope I can get the data back because there´s alot of important stuff in there.

Yes, I know I can´t blame anyone for this but myself for not setting up the backup

 

Edit: All hardware is brand new and running ECC memory.

 

Sincerely

//Andreas

Solved

Forgot to mention.

a couple of days ago I did a clean shutdown to permanently place the server. It didn´t start up into GUI and stopped booting with an error that I don´t remember. I turned off the power and started it into GUI without any problems.

If the options on the FAQ don't help best bet it to post on the btrfs mailing list (or their IRC channel), but since you used check --repair your options might be limited.

So darn relieved!!!

I managed to retreive all my data by externally connecting it to one of my desktops using Paradox BTRFS driver 😌
