Currently I'm looking for topics for my master thesis. One of my ideas was to work on Btrfs. I studied the list of project ideas at https://btrfs.wiki.kernel.org/index.php/Project_ideas and am especially interested in working on one of the following topics: > > 1. (Enhanced) hot spare support as described in https://btrfs.wiki.kernel.org/index.php/Project_ideas#Hot_spare_support and https://btrfs.wiki.kernel.org/index.php/Project_ideas#.22Enhanced.22_.28ala_RAID.29_support > > 2. Adding more checksumming algorithms ( https://btrfs.wiki.kernel.org/index.php/Project_ideas#More_checksumming_algorithms ) > > 3. Improving subvolume handling regarding taking recursive snapshots ( https://btrfs.wiki.kernel.org/index.php/Project_ideas#Take_recursive_snapshots ) and taking snapshots of arbitrary directories ( https://btrfs.wiki.kernel.org/index.php/Project_ideas#Snapshot_arbitrary_directories ) Another option that I would personally love to see would be support for write-mostly devices (that is, devices in a RAID1/RAID10 setup that only get written too unless the data can't be found elsewhere). This would in particular provide an alternative to using bcache/dm-cache (namely an SSD and HDD in RAID1 with the HDD set to write-mostly). Based on the current development focus, I don't think anybody is working on this already (I would be, but I don't have either the time or the skills with kernel programming that would be needed).
