> Is there anything I missed for steps to reproduce it? All the story is in previous mails. http://thread.gmane.org/gmane.comp.file-systems.btrfs/16829 http://www.mail-archive.com/linux-btrfs@xxxxxxxxxxxxxxx/msg15949.html First mail is missing from mail-archive... Summary: Some damaged sectors on one device. Seems to be ok after rewriteing so I started a scrub. During scrub (kernel 3.2.x) device completely broke down with A LOT of dameged sectors ---> other device fills up --> out of space ---> unclean shotdown. With 3.3 kernels I was able to mount it and add a new device. I tried 3.4-rc4 but the patch wasn't there. I had problem compiling from git, before I tried DKMS, then the whole kernel, (set CONCURRENCY = 5 with quadcore is wrong? ) so I waited rc5. With the tar from kernel.org I have successfully compiled 3.4-rc5 (with CONCURRENCY = 4). Errors with scrub. Here we are.

Yes. I tell you now what I did before your response today. >From this point: btrfs fi sh Label: 'RootFS' uuid: c87975a0-a575-405e-9890-d3f7f25bbd96 Total devices 3 FS bytes used 1015.83GB devid 3 size 1.75TB used 357.00GB path /dev/sdb3 devid 1 size 1.75TB used 1.34TB path /dev/sda3 *** Some devices missing I reached: btrfs fi show Label: 'RootFS' uuid: c87975a0-a575-405e-9890-d3f7f25bbd96 Total devices 3 FS bytes used 1004.23GB devid 3 size 1.75TB used 1.25TB path /dev/sdb3 devid 1 size 1.75TB used 1.33TB path /dev/sda3 *** Some devices missing using "btrfs balance start -dvrange=1..[group where it fails minus 1] " a number of times (I started writing some notes on http://btrfs.ipv5.de/index.php?title=User:Tyrael ).
