资 源 简 介
Lisanfs is a simple but strong distributed filesystem based on OSD.
As we know, like most of other distributed storage system, it should includes some components, clients, mds(meta-data server), ds(data server).
"Using OSD alows us to focus on management and scalability issues, while letting the OSD handle the physical disk chores of block allocation and mapping". OSD makes lisanfs very simple.
Lisanfs works following the nfsv4.1, and we can use pnfs clients/pnfsd supporting OSD layout in the kernel, which simplify our work further.
The most important work I do for lisanfs is that we modify reiserfs to act as MDS, for reiserfs works perfectly for small files, and the feature is just what we need.
Using not that much work, the project workes. We need do more work on MDS, making it more impressive, like AutoRaid features, MDS HA by mirror/standby support, better Scalability, etc.
Here, I want to thank Boaz Horrash sincer
