Ok, since Shaggy hasn't piped in I'll try and answer your questions. > Questions: > > 1) With service pack 1 applied to SLES 9 is there anything I'd be > missing in terms if important JFS patches? SLES 9 SP1 should most if not all of the recent bugfixes. > 2) Are the default mkfs.jfs options ok?

Yeah JFS doesn't preallocate groups or aggregates at mkfs time so there's really not much to specify unless you need to set up an external journal or set a volume label. > 3) Is there any reason not to use jfs for an NFS server? There shouldn't be, we've used it fairly extensively on NFS servers. > 4) Are there issues with SMP systems + JFS + NFS? Again, there shouldn't be, we've run JFS on many different servers/archs without problems. > 5) Are there any tuning options I should consider? If you're typical workload is very meta-data intensive with lots of threads etc. you might want to increase the nTxLock or nTxBlock module parameters, but in general it shouldn't be necessary.
