[Users] NFS issue using ovirt-node-iso-2.5.5-0.1.fc17

[Sven Knohsalla]

Hi,

I just wanted to update that NFS is working now with ovirt-node-iso-2.5.5-0.1.fc17,
but I had to change /etc/nfsmount.conf in the following line:

89 # Enable File Locking
90 # Lock=True (seems to be true per default, although commented out)

to:

# Enable File Locking
Lock=False

Is there anybody else, who is running in the same problem?

Thanks in advance!

Kind regards, Sven.

Hi,

just created a test environment, including ovirt-engine 3.1 + ovirt-node-iso-2.5.5-0.1.fc17 + qnap iscsi + qnap nas (NFSv3).
iSCSI connection is working fine.
When connecting to Export/ISO Domain via webgui the progress is taking forever (waited ~ 10 mins)

Back to console I first tried to connect from ovirt-engine to nfs storage of our NAS:

showmount -e 172.16.101.95 ->
Export list for 172.16.101.95:
/NFS-ISO01
/Export-NFS01
/...
mount -t nfs 172.16.101.95:/Export-NFS01 /mnt/nastest/
mount ->
172.16.101.95:/Export-NFS01/ on /mnt/nastest type nfs (rw,relatime,vers=3,rsize=32768,wsize=32768,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys,
mountaddr=172.16.101.95,mountvers=3,mountport=56272,mountproto=udp,local_lock=none,addr=172.16.101.95)

Touching a file on mountpoint is working,too.

On ovirt-node:

showmount -e 172.16.101.95->
Export list for 172.16.101.95:
/NFS-ISO01
/Export-NFS01
/...

mount -t nfs 172.16.101.95:/Export-NFS01 /mnt/nastest/ ->
mount.nfs: rpc.statd is not running but is required for remote locking.
mount.nfs: Either use '-o nolock' to keep locks local, or start statd.
mount.nfs: an incorrect mount option was specified

mount -t nfs 172.16.101.95:/Export-NFS01 /mnt/nastest/ -o nolock ->
working (also for vdsm)!

There's no firewall between NAS and node (except node fw)

rpcbind isn't installed on node:
http://gerrit.ovirt.org/#/c/4720/

It seems the package isn't needed anymore by this post in gerrit?

Well, how to proceed here?
Am I getting my wires crossed here or just missed a configuration?

Thx in advance!

Best,
Sven.
