Clustered version of XFS

[Tharindu Rukshan Bamunuarachchi]

we are using XFS high speed transaction processing system.

we are very happy with XFS performance compared to ZFS, EXT3, JFS etc.

i have two questions regarding XFS ...

1. Is there any cluster version of XFS. (e.g. like GFS, Luste, GPFS)
2. I am currently using my root partition as XFS. but i need to modify
XFS source code and reload module without rebooting machine.
    Is there anyway to play with XFS source/module while using XFS
module for mounted file system ....?


cheers
