     Thanks for the response Mike & Cliff,
     On our server though, which is basically a file server, serving 
     clients files over NFS. We have had 4-5 instances of xfs_shutdown 
     with message like "in-core memory corruption...." . 
     The exact messages are: 
     kerrnel: xfs_force_shutdown(lvm(58,2),0x8) called from line 1035 of 
     file xfs_trans.c.  Return address = 0xc01cc10a
     kernel: Corruption of in-memory data detected.  Shutting down 
     filesystem: lvm(58,2)
     kernel: Please umount the filesystem, and rectify the problem(s)
     At once, we had lost data even after repairing the filesystem using 
     xfs_repair and that too production data. Clearly, we are a worried lot 
     Would appreciate if I can get some information on concrete advantages 
     which XFS has over ext3/2 in terms of stability (specially as a file 
     server, performnace (with figures e.g how much % write/read gain) and 
     I believe we are using the XFS version which is as old as July 2001.

I use XFS exclusively on all my machines (at home and work).  This 
includes several desktops, a laptop, a couple of servers and even my 
firewall.  I've been using it for at least two years.  No other 
available filesystem (well, I haven't tested JFS and probably won't 
until I've got a 64-bit CPU) matches XFS for performance and 
reliability.  EXT3 is a joke (why *does* it need to fsck?), and 
ReiserFS, although very interesting, has had numerous problems.  My PC's 
have been turned off, crashed, and even attacked by ferrets without 
losing data or requiring repair.  What more can you ask of a filesystem?
