Talk:Shared disk file system

Unnamed section
Hi. Somebody added ZFS to this page, but, I don't think that ZFS does what they think it does. Cheers, 68.96.139.5 (talk) 06:23, 8 March 2008 (UTC)
 * ZFS is definitely not a clustered filesystem. Apparently clustering might be added one day but retrofitting it to an existing filesystem is troublesome IMHO. Robert Brockway (talk) 16:32, 19 November 2008 (UTC)

Not all clustered file systems are shared disk file systems, so I do not think the article should be merged inot Shared disk file system. An example would be something like IBRIX's file system or Lustre. Thunderbritches (talk) 02:51, 1 December 2008 (UTC)

The comparison section seems to have been directly ripped from a Sun Lustre whitepaper, without reference. See chapter 7 of: http://www.sun.com/software/products/lustre/docs/lustrefilesystem_wp.pdf —Preceding unsigned comment added by Sbeaky (talk • contribs) 21:33, 22 April 2009 (UTC)

Why are Shared Disk filesystems needed?
The article says that "Shared disk file systems are necessary because..." and blames it on concurrency problems in the clients. Yet you can have datacentre scale filesystems: Hadoop and Google File System are examples of this. Therefore shared disk file systems are not necessary, unless there is some other requirement of the filesystem that isn't explained. Someone needs to tune that section a bit. —Preceding unsigned comment added by SteveLoughran (talk • contribs)
