free space inode generation (0) did not match free space cache generation
Hello, I have a file-system on which I cannot write anymore (no space left on device, which is not true root@homeserver:~/btrfs/integration/devel# df -h Dateisystem Größe Benutzt Verf. Verw% Eingehängt auf /dev/sdd2 30G 24G 5,1G 83% /mnt/test1 ) About the filesystem: root@homeserver:~/btrfs/integration/devel# ./btrfs fi show /mnt/test1 Label: 'ROOT_BTRFS_RAID' uuid: a2d5f2db-04ca-413a-aee1-cb754aa8fba5 Total devices 2 FS bytes used 11.84GiB devid 1 size 14.85GiB used 14.67GiB path /dev/sde2 devid 2 size 14.65GiB used 14.65GiB path /dev/sdd2 Btrfs this-will-become-v3.13-48-g57c3600 Check of the filesystem: root@homeserver:~/btrfs/integration/devel# umount /mnt/test1 root@homeserver:~/btrfs/integration/devel# ./btrfsck /dev/sdd2 Checking filesystem on /dev/sdd2 UUID: a2d5f2db-04ca-413a-aee1-cb754aa8fba5 checking extents checking free space cache free space inode generation (0) did not match free space cache generation (41) free space inode generation (0) did not match free space cache generation (7380) free space inode generation (0) did not match free space cache generation (3081) checking fs roots checking csums checking root refs found 3680170466 bytes used err is 0 total csum bytes: 10071956 total tree bytes: 2398781440 total fs tree bytes: 2308784128 total extent tree bytes: 74203136 btree space waste bytes: 372004575 file data blocks allocated: 341759610880 referenced 75292241920 Btrfs this-will-become-v3.13-48-g57c3600 Before the btrfsck I did a mount -o clear_cache /dev/sdd2 /mnt/test1/ which in fact reduced the number of error messages (did not match free space cache generation) from more than ten to just three. I do have a backup of the FS and in fact it would have been quicker just whiping the disk and using the backup (just 16GB), than writing this message. But: Is it of interest to look at fixing this for someone, so that the development of btrfs can profit of this, or should I just whipe the disc?
