Greetings.

I've got a Linux box running the SGI-modified RedHat 7.1. Kernel is 
2.4.3-SGI_XFS_1.0.1smp. I'm exporting one of the xfs partitions via NFS, and 
trying to mount it on an HP/UX 11.00 machine.

The HP machine is able to mount nfs-exported ext2 partitions from another 
identical Linux box w/o a problem. However, when I try to mount a 
nfs-exported xfs partition, it is inaccessible after mounting. No error is 
returned while mounting, and I don't see an error in the Linux box's log.

# mount -F nfs -o hard,intr,rw tux:/u/rd/mga /mnt
# ls mnt
mnt unreadable
# df

---------

I am able to mount and access the partition if I specify vers=2 as one of the 
mount options. However, then I see the following behaviour: when any user 
tries to log into the HP machine, the login hangs for almost 1 minute. If I 
do a 'ps -elf' while somebody's logging in, I see that /usr/bin/quota's 
running for that user, and presumably that's what's hanging.

Anybody have any ideas/suggestions?

Thanks.
