Quotas issue - rpcbind: breaks nfs

[Aldo Foot]

Although I already have the fix to this question, I'm doing a bit of
detective work to find out why rpcbind breaks nfs when quotas are involved.

Preliminary notes:
 1. as of this posting my system if fully updated (and rebooted)
 2. I have not made any changes to /etc/sysconfig/nfs
 3. I'm running kernel 2.6.29.6-213.fc11.i686.PAE
 4. This is not a Virtual Machine.

I had this in /etc/fstab. A VG with quotas enabled.
      "/dev/myVG/lv1   /mnt/p2    ext3    defaults,usrquota,grpquota 1 2"

I removed the VG entirely, but did not disabled quotas in it before
removal. I don't know why this would be the source of the problem.

The rpcbind service is OK.

# service rpcbind status
rpcbind (pid 2977) is running...

# rpcinfo -p
   program vers proto   port  service
    100000    4   tcp    111  portmapper
    100000    3   tcp    111  portmapper
    100000    2   tcp    111  portmapper
    100000    4   udp    111  portmapper
    100000    3   udp    111  portmapper
    100000    2   udp    111  portmapper

When I try to start the NFS services I get a quotas related error message.

# /etc/init.d/nfs start
Starting NFS services:                                     [  OK  ]
Starting NFS quotas: Cannot register service: RPC: Authentication
error; why = Client credential too weak
rpc.rquotad: unable to register (RQUOTAPROG, RQUOTAVERS, udp). [FAILED]
Starting NFS daemon:                                       [FAILED]

I attempt to turn quotas off in the system (none found).
# quotaoff  - -all  - -off  - -verbose

Interestingly, when I "restart" as opposed to "start" the NFS services, there's
an "OK" message in there, but NFS does not start.

# /etc/init.d/nfs restart
Shutting down NFS mountd:                                  [FAILED]
Shutting down NFS daemon:                                  [FAILED]

Shutting down NFS services:                                [FAILED]
Starting NFS services:                                     [  OK  ]
Starting NFS quotas: Cannot register service: RPC: Authentication
error; why = Client credential too weak
rpc.rquotad: unable to register (RQUOTAPROG, RQUOTAVERS, udp).[FAILED]
Starting NFS daemon:                                       [FAILED]

The fix is to add this line to /etc/hosts.allow:
    "rpcbind :       127.0.0.1 EXCEPT PARANOID"
I got that from a somewhat related filed bug:
    https://bugzilla.redhat.com/show_bug.cgi?id=358621

The issue was fixed a while ago in F9:
   https://bugzilla.redhat.com/show_bug.cgi?id=249199
See also:
   https://bugzilla.redhat.com/show_bug.cgi?id=173495

So, why am I seeing this in F11?
How do I tell NFS that there are not quotas in any filesystem?
I don't want to reinstall F11 all over just to find out this answer.

If you have input, please share.

thanks,
