FYI: According to ddrescue, there were read errors in +45% of the partition. There were no chances to save anything from the disk. 2018-08-01 15:07 GMT+03:00 Cerem Cem ASLAN : > Yes, command output is as is, because I just copied and pasted into the > mail. When I omit the `-t btrfs` part,

Yes, command output is as is, because I just copied and pasted into the mail. When I omit the `-t btrfs` part, result is the same. I'm now trying to rescue what I can, so getting a image dump with `ddrescue`. It's read about 25% without any errors but it will be expected to finish in 6 hours.

Unmountable root partition

2018-07-31 Thread Cerem Cem ASLAN
Hi, I'm having trouble with my server setup, which contains a BTRFS root partition on top of LVM on top of LUKS partition. Yesterday server was shut down unexpectedly. I booted the system with a pendrive which contains Debian 4.9.18 and tried to mount the BTRFS root partition manually. 1.
