       Thanks for your reply. I added

/export/home/pickles 10.0.0.0/24(rw,insecure,root_squash,no_subtree_check,sync)

to /etc/exports and then did exportfs -r. Running exports told me it
was being exported:

spindizzy> exportfs
/export         10.0.0.0/24
/export/logs    10.0.0.21/24
/export/home    10.0.0.0/24
/export/home/pickles
                10.0.0.0/24
/export/public  10.0.0.0/24
spindizzy>

If I go back to the desktop, it claims fileserver is exporting pickles:

raub@desktop:~$ showmount -e fileserver
Export list for fileserver:
/export/public       10.0.0.0/24
/export/home/pickles 10.0.0.0/24
/export/home         10.0.0.0/24
/export/logs         10.0.0.21/24
/export              10.0.0.0/24
raub@desktop:~$

But, as before, when I tried to mount pickles, it doesn't:

fileserver:/home/raub     197G  164G   33G  84% /home/raub
fileserver:/home/pickles  197G  164G   33G  84% /home/pickles

Same outcome with crossmnt or nohide
