BTRFS quota support

BTRFS now has quota support, I couldn't find any documentation or specific information about it. If such documentation exists, I would appreciate a pointer... TIA. -- Swâmi Petaramesh sw...@petaramesh.org http://petaramesh.org PGP 9076E32E Ne cherchez pas : Je ne suis pas sur Facebook

Defragmenting open files

and was able to handle open files, but apparently not ? Another question is : Is there a way to determine if a directory needs a defrag ? filefrag doesn't seem to be able to work properly against a directory... TIA. Kind regards. -- Swâmi Petaramesh sw...@petaramesh.org http://petaramesh.org PGP

Does defragmenting even work

BTW... I'm not even sure that btrfs filesystem defrag somefile actually does anything... If I run filefrag somefile afterwards, it typically shows the same number of fragments that it did prior to running defrag... I'm not sure about how it actually works and what I should expect... -- Swâmi

Re: Does defragmenting even work

. Similarly, very large files may not be easy or possible to defragment fully -- a 2GB file with four fragments isn't exactly a problem, for example. Hugo. -- Swâmi Petaramesh sw...@petaramesh.org http://petaramesh.org PGP 9076E32E Ne cherchez pas : Je ne suis pas sur Facebook

recent kernel than the one that Ubuntu 13.04 will have would give me huge speed improvements or features I need much - (and I assume that being able to defrag, with my snapshots, would be a good reason for me...) Kind regards. -- Swâmi Petaramesh sw...@petaramesh.org http://petaramesh.org PGP
