Hello, (this is a recap of yesterday''s discussion on BTRFS IRC, also to save relevant pastes before pastebins expire) I have my /home on btrfs; a cronjob makes one snapshot every 30 minutes; these snapshots are kept for 24-48 hours, then deleted in batches. This is a 16K Leaf/Node BTRFS on top of mdadm RAID1. As system uptime approached 2 weeks, I started noticing that the free space

I''m running into a problem with the btrfs-cleaner thread becoming blocked on xfstests 068. The test locks up indefinitely without completing (normally it finished in about 45 seconds on my test box). I''ve replicated the issue on 3.10.0_rc5 and the for-linus branch of 3.9.0. I ran a git bisect on the 3.9.0 for-linus branch, and tracked my issue to the following commit: commit

Signed-off-by: Ilia Mirkin <imirkin at alum.mit.edu> --- This applies on top of Dave Airlie's r600g-texture-gather branch. Ran piglit with -t gather, passed all 1057 tests. Can't say I fully understand what all the arguments to handleTEX in the Coverter are but... seems to work. Will probably require some care for nvc0 support which should have SM5 caps.

The freeze rwsem is taken by sb_start_intwrite() and dropped during the commit_ or end_transaction(). In the async case, that happens in a worker thread. Tell lockdep the calling thread is releasing ownership of the rwsem and the async thread is picking it up. Josef and I worked out a more complicated solution that made the async commit thread join and potentially get a later transaction, but

Hello, I have a 5.5TB Btrfs filesystem on top of a md-raid 5 device.

This patch finally gives us full proper -ENOSPC handling for btrfs. Now whenever you do a btrfs_start_transaction, you must specify the number of items you are planning to add/delete/modify. The worst case number of blocks that could be modified by changing that number of items will be calculated and checked against the amount of free space in the space_info where the root you are modifying

Dear Devs, I have x4 4TB HDDs formatted with: mkfs.btrfs -L bu-16TB_0 -d raid1 -m raid1 /dev/sd[cdef] /etc/fstab mounts with the options: noatime,noauto,space_cache,inode_cache All on kernel 3.8.13. Upon using rsync to copy some heavily hardlinked backups from ReiserFS, I''ve seen: The following "block rsv returned -28" is repeated 7 times until there is a call trace

After doing something silly (not sure what yet) with a server''s 4-drive btrfs raid1 root, I''ve been booting off a 5th drive (also on btrfs) while poking at the original array. I''ve found that errors triggered by poking around on the mounted-but-broken 4-drive raid (on /mnt) cause the system to gradually lock up. This is a 2.6.37rc8 build without any extra patches;

Hi. I want to define my own cache store but I have no idea how to use in my app. Rails initializer reads environment config before loading app initializers and plugins. So, i cant write: config.cache_store = :my_beautiful_cache_store, ''localhost:641'' even if I put ActiveSupport::Cache::MyBeautifulCacheStore in config/ initializers. Now i think it is impossible to define my

V1->V2: Check to see if our current ppos is >= i_size after a short DIO read, just in case it was actually a short read and we need to just return. This is similar to what already happens in the write case. If we have a short read while doing O_DIRECT, instead of just returning, fallthrough and try to read the rest via buffered IO. BTRFS needs this because if we encounter a compressed or
