Man, I need to stop reading these things, because now it appears that I might have a problem. When I do a showmount -a (which is supposed to list all the mounts on the current system from other systems), I get a list of old mounts that no longer exist (in fact one of the servers doesn't even exist anymore), AND I don't see a directory that is mounted from another, non-AIX system.
My /etc/rmtab file contains the info about the old, non-existent mounts. The mount that exists isn't in /etc/rmtab.
But in smit, it only shows the mount that actually does exist. It doesn't show that I can delete the old mounts.
The system seems fine. Do I let sleeping dogs lie and forget about the discrepancy?
