Hi all, I have some naive questions regarding GFS and distributed file systems in general. 1. Can anyother distributed file system other than GFS/OCFS2 be used over GNBD? What are the chief differences between GFS and OCFS2? 2. when space is allocated for a file in GFS , does it do in such a way that it equalises space utilisation among the storage nodes? Which are the file i should see for understanding the general data-distribution algorithm used in GFS? 3. Given the recent advent of flash memories are there any "distributed-log structured" file system like Zebra, xFs(paper<a href="http://portal.acm.org/citation.cfm?id=224066"> Serverless network file system</a> ) that are developed lately? thanks, Mugunthan
