This is a self-reply. I have gotten a little closer to solving
this issue, but I am still lacking some info.
OK... what I have discovered is that this is not a Sun/Linux
issue. I can generate the errors from a linux box as well.
Essentially If I execute '/usr/bin/quota -v' on a client system
then the redhat nfs server spawns this error for each remotely
mounted directory:
rpc.rquotad: Can't find filesystem mountpoint for directory
/export/rd01/stack
rpc.rquotad: No correct mountpoint specified.
Is this being caused because the client does not have an
/export/rd01/stack directory ( it automounts this directory
under /projects/stack)? If so why does the error appear in the
server logs an not on the client?
As I have about 100 projects that I need to move to this server,
that's going to be a lot of error messages. I guess I could just
turn rquotad off, but it is started up in the nfs init script,
which would mean commenting it out of that script rather than
just using chkconfig to turn it off. I think the other option
may be just to deny rquota connections in /etc/hosts.deny. Does
anyone agree with this or have another idea to figure out why
this is giving this error message?
Thanks,
Jeff
