Hi,

HP does not support it. The link posted also mentions that HP never adopted it and IBM too has stopped marketing/servicing DFS.

Have a look at the link. See page 12-15.

Hi Shiv,

DFS file system is not supported by HP-UX. HP-UX only supports VxFS, HFS, CDFS.

DFS is not available on HP-UX but, it is available on Solaris 7,8 and 9.

Shalom Shiv,

Windows has DFS, which is integrated into Windows 2003 clustering.

In actual use at my prior employer it proved to be a bit buggy with random disconnects occuring under certain circumstances.

Linux has something called GFS, which with Oracle RAC supposedly lets you have two nodes or more running, accessing the same database file in read/write mode.

At this time, I know of no HP-UX equivalent. There may be products from Veritas, which is now part of Symmantec that provide similar functionality as part of the Veritas Cluster suite. If you must have DFS like functionality on HP-UX, that is where you should search.

Actually, HP-UX 11.23 under MG/SG does have a new Cluster File System (CFS) that is a fully read-write multi-host filesystem that looks to each host as simply a vxfs filesystem. It does require a dedicated network for the filesystem communication but buffer cache consistancy is maintained across all hosts.

Hi Shiv,

Are you asking about Distributed File System (DFS) used in Windows clusters? If yes, You can try Veritas Storage Foundationâ ¢ Cluster File System

If I remember correctly, long ago there was a DFS as part of DCE. It sounded good back in the 90's but never took off. IBM tried to keep it going but there is just no market for this technology. I would suggest that you avoid it. Microsoft's DFS is completely different.
