Hi all. I was doing some testing with writing out data to a BTFS filesystem with the compress-force option. With 1 program running, I saw btfs-delalloc taking about 1 CPU worth of time, much as could be expected. I then started up 2 programs at the same time, writing data to the BTRFS volume. btrfs-delalloc still only used 1 CPU worth of time. Is btrfs-delal...

Hi, I reported a bug to anaconda (rhbz 901905), but it might be btfs related.

...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 user load, but high in state waiting to IO. Extreme slowdown of the system, application freezes for more than a minute... I tried to manually defrag my home parition and also added the autodefrag mount option but this changed...

I notice this question on the wiki/faq: https://btrfs.wiki.kernel.org/index.php/UseCases#What_is_best_practice_when_partitioning_a_device_that_holds_one_or_more_btr-filesystems and as it hasn''t been answered, can anyone make any comments on the subject Various things come to mind: a) partition the disk, create an LVM partition, and create lots of small LVs, format each as btrfs b)

I''ve created a test volume and copied a bulk of data to it, however the results of the space allocation are confusing at best. I''ve tried to capture the history of events leading up to the current state. This is all on a Debian Wheezy system using a 3.10.5 kernel package (linux-image-3.10-2-amd64) and btrfs tools v0.20-rc1 (Debian package 0.19+20130315-5). The host uses an

This is a first draft of a subvolume quota implementation. It is possible to limit subvolumes and any group of subvolumes and also to track the amount of space that will get freed when deleting snapshots. The current version is functionally incomplete, with the main missing feature being the initial scan and rescan of an existing filesystem. I put some effort into writing an introduction into
