Hi, I have worked on my script and have interesting new findings about the "old" filesystem, the one that used to have the huge spread between Size and Used for Metadata. I have uploaded the script to http://q.bofh.de/~mh/stuff/20160327-btrfs-balance and a current full syslog to http://q.bofh.de/~mh/stuff/20160326-linux-btrfs-ofanbtr Current state is: (1) Filesystem has been resized to 300 GB. This has solved the "Superblock bytenr is larger than device size" message on btrfs check. btrfs check now runs through fine, output below. (2) Umounting the filesystem results in a kernel trace, given below as well. (3) Metadata spread is down to 27GiB/2.31 GiB, decreases to 10Gib/2.30GiB and increases again during the run of my btrfs-balance script: [7/507]mh@fan:~$ grep "Metadata, DUP" 20160326-linux-btrfs-ofanbtr Mar 26 09:49:40 fan root: Metadata, DUP: total=27.00GiB, used=2.31GiB Mar 26 10:26:15 fan root: Metadata, DUP: total=10.50GiB, used=2.30GiB Mar 26 11:01:52 fan root: Metadata, DUP: total=10.50GiB, used=2.31GiB Mar 26 11:03:36 fan root: Metadata, DUP: total=14.50GiB, used=2.30GiB Mar 26 11:03:36 fan root: Metadata, DUP: total=14.50GiB, used=2.30GiB Mar 26 11:38:40 fan root: Metadata, DUP: total=19.00GiB, used=2.31GiB [8/508]mh@fan:~$ (4) The attached log gives the following indications: Mar 26 09:49:40 fan root: Metadata,DUP: Size:27.00GiB, Used:2.31GiB Mar 26 09:49:40 fan mh: BEGIN btrfs balance start /mnt/ofanbtr Mar 26 10:26:15 fan root: Done, had to relocate 134 out of 134 chunks Mar 26 10:26:15 fan root: Metadata, DUP: total=10.50GiB, used=2.30GiB Mar 26 10:26:15 fan mh: BEGIN btrfs balance start -dprofiles=single /mnt/ofanbtr Mar 26 11:01:52 fan root: Done, had to relocate 79 out of 101 chunks Mar 26 11:01:52 fan root: Metadata, DUP: total=10.50GiB, used=2.31GiB Mar 26 11:01:52 fan mh: BEGIN btrfs balance start -mprofiles=dup Mar 26 11:03:36 fan kernel: [ 4693.269593] BTRFS info (device dm-31): 9 enospc errors during balance Mar 26 11:03:36 fan root: ERROR: error during balancing '/mnt/ofanbtr': No space left on device Mar 26 11:03:36 fan root: There may be more info in syslog - try dmesg | tail Mar 26 11:03:36 fan root: Metadata, DUP: total=14.50GiB, used=2.30GiB Mar 26 11:03:36 fan mh: BEGIN btrfs balance start --force -sprofiles=dup /mnt/ofanbtr Mar 26 11:03:36 fan root: Done, had to relocate 1 out of 109 chunks Mar 26 11:03:36 fan root: Metadata, DUP: total=14.50GiB, used=2.30GiB Mar 26 11:03:36 fan mh: BEGIN btrfs balance start /mnt/ofanbtr Mar 26 11:38:40 fan kernel: [ 6796.907286] BTRFS info (device dm-31): 9 enospc errors during balance Mar 26 11:38:40 fan root: ERROR: error during balancing '/mnt/ofanbtr': No space left on device Mar 26 11:38:40 fan root: There may be more info in syslog - try dmesg | tail Mar 26 11:38:40 fan root: Metadata, DUP: total=19.00GiB, used=2.31GiB Note, that the initial btrfs balance start runs without ENOSPC, the btrfs balance start -mprofiles=dup errors out, and the final btrfs balance start errors out again. We thus have the case where a script run has actually worsened the state of the filesystem. Is this worth adding to the bug report (https://bugzilla.kernel.org/show_bug.cgi?id=114451)? Should I include a new btrfs image? What else should I include? Any ideas?
