NFS version

[galindro]

Sometimes I have a permission denied problem when I try to mount the share from one allowed node (in this case, 192.168.1.141/32). I don't know why or when this happens (I mean what is the issue's trigger), but I think that is caused by ZoL because the problem is solved only when I set the nfsshare property to off and then to rw=@192.168.1.141/32,insecure.

The NFS server is m01 (192.168.1.113)
The NFS client is servicos (192.168.1.141)

BEFORE RESET nfsshare option

One configuration that I have changed, before reset the nfsshare option in nfs server, was the nfs protocol version from nfs to nfs4 on /etc/fstab of nfs client, but I don't know if it will solve the issue definitely...

#CLIENT
root@servicos:~# grep moodle /etc/fstab
192.168.1.113:/var/moodle_quarentena_videos /var/moodle_quarentena_videos nfs4

What do the server say when you try to do the mount? Is this the only share you have?

Could this be related to #1442?
