Can you confirm that the NFS server is on a Centos7 system?
Is NFS-v3 required, or can you switch to NFS-v4?
FWIW, I installed a Centos7 VM. And enabled nfs-server.service. The
server has the following:
[root@cos7 etc]# firewall-cmd --get-active-zones
public
interfaces: eth0
[root@cos7 etc]# firewall-cmd --info-zone=public
public (active)
target: default
icmp-block-inversion: no
interfaces: eth0
sources:
services: dhcpv6-client mountd nfs nfs3 rpc-bind ssh
ports:
protocols:
masquerade: no
forward-ports:
source-ports:
icmp-blocks:
rich rules:
[root@cos7 etc]# cat exports
/home/egreshko
2001:b030:112f:2::0/64(rw,sync,insecure,no_root_squash,no_subtree_check)
/home/egreshko
192.168.0.0/16(rw,sync,insecure,no_root_squash,no_subtree_check)
On an F33 VM I have the following in /etc/fstab
#[2001:b030:112f:2::41]:/home/egreshko /mnt nfs defaults 0 0
[2001:b030:112f:2::41]:/home/egreshko /mnt nfs nfsvers=3,defaults 0 0
And, I am able to mount using either nfs-v3 or nfs-v4
I can mount fine. The problem is that various programs (LyX,
LibreOffice) freeze when attempting to open files on those filesystems.
In LyX, I was able to trace the problem to a call to lockd, which never
returns. So it seems there is some problem with file locking, which it
was suggested involved some firewall problem. Which it does, since
disabling the firewall on the server solves the problem. (There's no
firewall on the client.)
