I can't umount the partition, delete a snapshot or write anything. I try to reboot the system, but the problem is still present. Here the "frozen transaction" : $ ps auxw | grep btrfs | grep D root 1835 0.0 0.0 0 0 ? D Oct08 0:13 [btrfs-cleaner] root 1836 0.0 0.0 0 0 ? D Oct08 0:01 [btrfs-transacti] root 2633 0.0 0.0 0 0 ? D Oct08 0:00 [flush-btrfs-1] The partition is mounted with this options : # mount | grep btrfs /dev/mapper/vg--sofia-backup on /backup type btrfs (rw,noatime,compress-force=zlib,nossd) The disk is near full : # btrfs fi df /backup/ Data: total=482.68GB, used=480.89GB System, DUP: total=32.00MB, used=72.00KB System: total=4.00MB, used=0.00 Metadata, DUP: total=10.12GB, used=8.82GB But one of the last actions was the removing of some big subvolumes (near 50GB). There is no error in logs, the frozen transaction was started from a 3.5* kernel (from GIT), and the system is now running on a 3.6.1 kernel (vanilla). Is there something I can do to solve that problem ? Thanks, Olivier
