Hi All, The official wiki seems to have lost references to "scrub" if not other commands. The last changes iss filled with account creation so I can''t see easily when that happened. Have I missed a policy change go through which is not reflected in the (Debian/Siduction) btrfs userland program yet or has something else happened? Kind regards -- To unsubscribe from this list:

Provide for modification of the limit of compressed extent size utilizing mount-time configuration settings. The size of compressed extents was limited to 128K, which leads to fragmentation of the extents (although the extents themselves may still be located contiguously). This limit is put in place to ease the RAM required when spreading compression across several CPUs, and to make sure the

If there''s is a long name directory exists in the /dev, then an overflow will hit in function utils.c btrfs_scan_one_dir:1013! The minimal fix is to use snprintf instead of strcpy. The reason why not using strncpy is that, if there is no null byte among the first n bytes of src, the string placed in dest will not be null - terminated. Signed-off-by: Rock Lee

Hello, The question below is based on https://lists.ubuntu.com/archives/xubuntu-users/2012- August/004509.html Thanks in advance for any help with the following question, including pointing me to some other info resource if needed.

Hi all, Just a quick question but can''t find an obvious answer. Can I create/convert a existing (btrfs) directory into a subvolume? It would be very helpful when transferring ''partitions'' into btrfs. I found a similar question way back in google, but that site is down now generally.

Hello, is it possible to set nodatacow on a per-file basis? I couldn''t find anything. If not, wouldn''t that be a great feature to get around the performance issues with VM and database storage?

Hi all - Here''s my current error handling patchset, against 3.1-rc8. Almost all of this patchset is preparing for actual error handling. Before we start in on that work, I''m trying to reduce the surface we need to worry about. It turns out that there is a ton of code that returns an error code but never actually reports an error. The patchset has grown to 65 patches. 46 of them
