1.i need gfs2 or ocfs2 to store xen-disk image file(20G--100G),it is big file. the underlying storage is fc-san. both of them have cluster sence.so they fit for me.
if gfs2 is ready for product? anyone use gfs2 in product? stability is the most important thing.
2.i have try gfs2 and ocfs2 , iozone shows , gfs2 has a good throughput when record>=512k and file size > 4G.
3.my kernel is 2.6.32 and latest.
