Hi

I had the same problem (F11)
The cure for me was to ensure that the name of the local machine (naxos) is
available to "mount"
Putting the name in /etc/hosts on naxos does the job

naxos ~ 2# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4 naxos
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

It is not good enough that hostname is set

My advice would be to reboot after adding the name to /etc/hosts
(assuming its missing) I wasted hours stopping and starting rpcidmapd type services
before discovering I had fixed the problem in the first 5 minutes
but that a clean restart was needed !

/etc/host.conf has changed in F11 I played with this as
well but don't think its relevant
multi on
order hosts,bind

---------------------------------------------------
In case the problem is on the server side (maui) Centos 5.3
my files look like this

maui.jaa.org.uk ~ 1# cat /etc/exports
/exports                148.197.29.0/24(rw,insecure,sync,wdelay,no_subtree_check,no_root_squash,fsid=0)
/exports/global 148.197.29.0/24(rw,insecure,sync,wdelay,no_subtree_check,nohide,no_root_squash)
/exports/home   148.197.29.0/24(rw,insecure,sync,wdelay,no_subtree_check,nohide,no_root_squash)
----------------------------------------
maui.jaa.org.uk ~ 2# cat /etc/fstab
...
LABEL=global_maui               /global                 ext3    defaults        1 2
LABEL=boot_maui                 /boot                   ext3    defaults        1 2
...
/home                           /exports/home           none     bind    0 0
/global                         /exports/global         none     bind    0 0
---------------------------------------
maui.jaa.org.uk ~ 4# cat /etc/auto.master
...
/home   auto.home
/-      auto.direct
--------------------------------------
maui.jaa.org.uk ~ 4# cat /etc/auto.home
#*      -fstype=nfs     148.197.29.5:/exports/home/&
*       -fstype=nfs4,rsize=32768,wsize=32768    148.197.29.5:/home/&
--------------------------------------
maui.jaa.org.uk ~ 5# cat /etc/auto.direct
#/global    -fstype=nfs  148.197.29.5:/exports/global
/global    -fstype=nfs4  148.197.29.5:/global

Note the # commented nfs3 lines

Hope this helps

John
