...process on the btrfs volume took 465 minutes... BackupPC uses hard links for unchanged files between backups, if that''s relevant. When copying a large file over gigabit, I''m getting around 50MB/s burst speed for about 30s, followed by a minute of 0B/s when btrfs-submit and btrfs-transaction are at 99% IO in iotop but minimal READ/WRITE. Is there anything I can do to relieve that? If more details can help, I''ll gladly provide them. [1] http://pastebin.ubuntu.com/5755800/ Thanks, -- Michał (Saviq) Sawicz <michal@sawicz.net>

Running an Ubuntu Raring VM which was built a week ago that is now running 3.8-rc6, I was booting it last night when it hung. After a few forced reboots, it came back up and I found the attached in kern.log. Mostly, the VM has been used for testing anisble deployment, so not a lot of work, just upgrading and installing software, then rebooting. Are these reports useful? Is there any

...ox and Chromium profiles, GNOME Zeitgeist, Ubuntu Desktop Couch, Banshee, and Evolution''s datastore.) Workarounds include manually defragmenting your home directory using btrfs fi defragment. Auto-defragment (mount option autodefrag) should solve this problem in 3.0. Symptoms include btrfs-transacti and btrfs-endio-wri taking up a lot of CPU time (in spikes, possibly triggered by syncs). You can use filefrag to locate heavily fragmented files. Symptoms are: Very high load, btrfs-transacti, btrfs-endio-wri and other btfs kernel threads producing high IO load (iotop). top shows low system and u...
