The analysis above is subject to verification of any custom config on your
server and client in:
/etc/sysconfig/nfs
Now the analysis.
network fs services script:
/etc/init.d/netfs start
...
< based on /etc/fstab >
service rpcbind start
action $"Mounting NFS filesystems: " mount -a -t nfs,nfs4
action $"Mounting CIFS filesystems: " mount -a -t cifs
action $"Mounting NCP filesystems: " mount -a -t ncpfs
...
touch /var/lock/subsys/netfs
action $"Mounting other filesystems: " mount -a -t nonfs,nfs4,cifs,ncpfs,gfs
Comments:
man mount.nfs or mount.nfs4 says:
...
mount.nfs4 is used for mounting NFSv4 file system, while mount.nfs is
used to mount NFS file systems versions 3 or 2.
...
First it calls 'mount -a -t nfs,nfs4',
then it calls 'mount -a -t nonfs,nfs4,...'
Why the second call (except for gfs) ?
Should there be also nonfs4, nocifs, noncpfs ?
This probably caused some confusion as it might have attempted to overwrite
previous (first call) nfs assignment with nfs4.
We hava a case that client's /etc/fstab specified "nfs" fs type for 3 shares
obtainable from the same server (even the same Fedora 14 on both server and
client), but obtained nfs3 for one share (/home) and nfs4 for 2 others. Why ?
You already have the nfs network set up for this.
You should be able to debug it inside this script by placing debugging
statements recording /etc/mtab AND /proc/mounts after each 'mount'.
If you confirm it, I will be able to request a fix in Bugzilla.
It would also indicate some bug in 'mount' itself as I am not sure that 'mount'
should be allowed to overwrite one fs type with another, here nfs with nfs4.
You can test it manually as well.
