[Jfs-discussion] JFS in SuSE Enterprise 9

[Chris P. <cp...@gm...>]

I'm considering using JFS for an NFS server and I'm curious if anyone
has any feedback on any of the following questions.  The hardware is a
dual cpu pentium 4 with 2gb ram, gigabit ethernet, and dual qlogic
23xx hbas running SuSE Enterprise 9 w/ SP1.  I'm using lvm2 to turn
four 1TB luns into a 4TB volume.

Questions:

1) With service pack 1 applied to SLES 9 is there anything I'd be
missing in terms if important JFS patches?

2) Are the default mkfs.jfs options ok?  There doesn't seem to be any
options to specific stripe widths, etc.  I assume it autodetects or
doesn't need that?

3) Is there any reason not to use jfs for an NFS server?

4) Are there issues with SMP systems + JFS + NFS?

5) Are there any tuning options I should consider?
