The evolution of file system
an idea by ganghe
Study the evolution of file system in the past years, know the current active file system project and technical trends.
OCFS2 optimization on hybrid storage investigation
an idea by ganghe
Nowadays, SSD (fast hard disk) is very popular, but still expensive. Some users want to use some SSD hard disks and some common hard disks to set up a hybrid storage infrastructure, in this case, how does OCFS2 file system utilize these SSD hard disks effectively? so far, we have not any particular optimization, OCFS2 considers these hard disks as one kind of hard disk. So, I want to investigate what we can do in improving OCFS2 under a hybrid storage infrastructure, let OCFS2 be able to aware fast hard disks, and use them more effectively.
Learn and use Openattic
a project by ganghe
As you know, SUSE acquired Openattic last year, which is a great storage management system.
Learn about log-structured file systems
a project by ganghe
Compared with traditional file systems (e.g. EXT4, XFS), log-structured file systems treat its storage as a circular log and write sequentially to the head of the log. I want to learn about this kind of file system via this hack week, to understand how it manages its data and metadata, to understand how it recover back from crash, to understand its advantages and disadvantages.
File system block allocation algorithms comparison and analysis
a project by ganghe
In the past, some customers ever complained that OCFS2 file system performance went down when listing a big directory (e.g. include 400k files). According to my preliminary investigation, this performance problem is related to file system block allocation algorithm. Then, I want to look at the current mainstream file systems (e.g. EXT4, XFS, etc) block allocation algorithms in this hack week, compare and analysis these algorithms advantages/disadvantages.
