hello, Chris In the next several months, I will have a lot of spare time. I will be happy if you assign some work to me. I have learn linux kernel for years but only fix a few small bugs in IP stack. In the past few months, I read some EXT4/VFS codes. I began reading source of btrfs ten days ago and have read it twice now. Regards YZ

Dear Sirs and Madams, I run a small visual effects production company, Hammerhead Productions. We'd like to have an easily extensible inexpensive relatively high-performance storage network using open-source components. I was hoping that OCFS2 would be that system. I have a half-dozen 2 TB fileservers I'd like the rest of the network to see as a single 12 TB disk, with the aggregate
