Need help with btrfs.

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

I have converted a large ext4 filesystem to btrfs and by accident deleted an important users home directory. Reading btrfs doc seems to imply that the directory can be recovered without reverting the filesystem to ext4.

What I've read seems to be telling me to mount the subvolume ext2_saved and then mount the image file residing in that directory. 

I am VERY new to btrfs and am seeing some troubling output (see below).

Here's what I've done and what I'm seeing. Could someone help me with this please?

Best regards,

George...
