Can not get locks on NetApp NFS

TZHANGPAC — Thu, 05 Jun 2025 06:13:02 GMT

Hi,

I got a problem when I trying to get lock from NetApp NFS.

The NFS client is centos6.0, NFS v3. The NFS server is NetApp.

The NFS client is a virtual machine running on Xen Server. The NFS client has nfs, nfslock, rpcbind processes runnning.

I use mount command to mount the NFS to the client.

I use the below command mount the NFS.

mount -t nfs etNAS:/et-data /et/nfs/data

After mount, the storage is mount, I can create file on the /et/nfs/data folder. But I can not get lock on the folder. I got No locks available error. Actually the file is not locked by others.

Could anyone help on this?

The output of the commands

[etadm@lab-dev-def-msg002 sysconfig]$ mount

etNAS:/et-data on /et/nfs/data type nfs (rw,lock,soft,addr=172.31.80.240)

[etadm@lab-dev-def-msg002 sysconfig]$ cat /proc/mounts

etNAS:/et-data /et/nfs/data nfs rw,relatime,vers=3,rsize=65536,wsize=65536,namlen=255,soft,proto=tcp,timeo=600,retrans=2,sec=sys,mou ntaddr=172.31.80.240,mountvers=3,mountport=4046,mountproto=udp,addr=172.31.80.240 0 0

I tried mount the NFS using another Linux NFS server instead of NetApp.

1.Mount the NFS folders with NFS4, the client can get the lock.

[root@lab-dev-def-msg001 ~]# mount 172.16.108.132:/home /mnt/nfs

[root@lab-dev-def-msg001 ~]# more /proc/mounts

172.16.108.132:/home/ /mnt/nfs nfs4 rw,relatime,vers=4,rsize=262144,wsize=262144,namlen=255,hard,proto=tcp,p

ort=0,timeo=600,retrans=2,sec=sys,clientaddr=172.31.80.131,minorversion=0,addr=172.16.108.132 0 0

2.Mount the NFS folders with NFS3, the client can NOT get the lock.

[root@lab-dev-def-msg001 ~]# mount -t nfs -o vers=3,lock 172.16.108.132:/home /mnt/nfs

[root@lab-dev-def-msg001 ~]# more /proc/mounts

172.16.108.132:/home /mnt/nfs nfs rw,relatime,vers=3,rsize=262144,wsize=262144,namlen=255,hard,proto=tcp,tim

eo=600,retrans=2,sec=sys,mountaddr=172.16.108.132,mountvers=3,mountport=41248,mountproto=udp,addr=17 2.16.108

.132 0 0

3.But I can NOT mount the NetApp with type NFS4. It mounts the NetApp with default NFS3.

[root@lab-dev-def-msg001 ~]# mount -t nfs -o vers=4 etNAS:/et-data /et/nfs/data

mount.nfs: Protocol not supported

Could anyone help me? How to mount the NetApp as NFS4?

Thanks
