Repost of what I sent to the mailing list just now: My current interpretation of this problem is that it is some pathological condition caused by not rebalancing and being nearly out of space for allocating more metadata and hence it is rarely being seen by anyone else (because most users are regularly doing rebalances).
See this thread for details about rebalancing and out of space: "ENOSPC with mkdir and rename" on 2014-08-02: http://thread.gmane.org/gmane.comp.file-systems.btrfs/37415 I haven't had the lockups in production since July and I'm now trialling a nightly rebalance: $ btrfs filesystem balance start -dusage=50 -musage=10 "$mount" I'll report back if I encounter further problems. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1349711 Title: Machine lockup in btrfs-transaction To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1349711/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
