Hello,
I have a netapp NFS server, from which I need to mount the NFS export
with the client option:
vers=4.1.
The reason is, that the server exports 4.2, but this has some issue
with SSC therefore we need to downgrade the client, which uses
userspace copy in 4.1
For example, the fs5 export should be mounted like this:
fs5.domain.de:/vol/fs5_m_scratch on /m/scratch/space type nfs4
(rw,nosuid,nodev,relatime,vers=4.1,rsize=65536,wsize=65536,..)
My idea was to use ("man nfsmount.conf")
[root@v110it01 nfsmount.conf.d]# pwd
/etc/nfsmount.conf.d
[root@v110it01 nfsmount.conf.d]# cat netapp.conf
[ NFSMount_Global_Options ]
Defaultvers=4.2
[ Server "fs5.domain.de" ]
rsize=32768
vers=4.1
[ Server "fs6.domain.de" ]
vers=4.1
This does not work, it uses vers=4.2.
The only thing which seems to work reliably is to use the
NFSMount_Global_Options.
If it works, I can reverse the entries and then it does not work anymore.
This is a bit strange, but its harder to reproduce a working mount,
than a non working.
I monitor the mount with and then edit the file in another terminal
while true ; do
mount fs5.domain.de:/vol/fs5_m_scratch /mnt/
mount | grep /mnt
sleep 4
umount /mnt
sleep 1
done
If I add rsize, for fs5 this is used, but not the vers=4.1.
If I change the name from fs6 to fs5 and have two fs5 entries it works too,
as soon I change it back to fs6 the mount is vers=4.2.
This is verified for :
- nfs-utils-2.5.4-27.el9.x86_64 (el9)
- bookworm (debian)
best regards,
Martin
