Subject: Debugging mount failure with netgroup
Date: Mon, 7 Feb 2011 13:56:09 -0600 [thread overview]
Message-ID: <20110207195609.GA13225@adept.internal.excfb.com> (raw)
Trying to mount:
[root@wont ~]# mount -o vers=3,hard,intr adept:/fooper /t/adept
mount.nfs: access denied by server while mounting adept:/fooper
[root@wont ~]# uname -a
Linux wont.internal.excfb.com 2.6.35.10-74.fc14.x86_64 #1 SMP Thu Dec 23 16:04:50 UTC 2010 x86_64 x86_64 x86_64 GNU/Linux
[root@wont ~]# showmount -e adept

The success at 13:37:14 was from when I changed the export to:
[root@adept ~]# exportfs
/fooper 192.168.2.0/255.255.255.0
to verify that NFS was working. At that point I was able to mount,
create a file, etc.
Oh yeah, the NFS server is also the NIS and DNS server, so there
shouldn't be any connectivity issues.
What can I do to further triage this?
Thanks!
