View as plain text  
SGI's press release *implies* that they will only be releasing a
"32-bit" version of XFS as open source.  It is not at all clear whether
or not that refers to the fact that the code is not 64-bit-clean, or
whether there is in fact some *difference* in the 64-bit version that
exists in IRIX v6.

I strongly suspect that we will see RedHat's JFS somewhat sooner than
XFS.  Based on experience with IRIX, XFS is just as susceptible to
corruption as the popular ext2fs.  I just lost an entire server because
of a poorly-seated SCSI cable; it came off while the system was running
and I no longer have a filesystem on /d2.  xfs_repair did about as good
a job as running SCANDISK under DOS.  *sigh*
(Guess where the mail spool was. :-(   I've unplugged a running Linux
box without that kind of damage!)

What I'd really like to see is Veritas' VFS ported to Linux - that's one
cool file system!  [Don't know why, but databases running under VFS
often run faster, which is kinda counterintuitive to me.]
