Hello,
I can't, for the life of me, get NFS mounts
working from clients. Any help is
greatly appreciated.
OS:
Debian 8.6
GlusterFS
3.8.4-1 installed using the
GlusterFS Debian repos.
Mounting using the native (glusterfs) client works but
not as fast as I would like it to, so I have to use NFS.
This is the result
of the mount command:
root@1:~# mount -vvv -t nfs -o
mountvers=3 server2:/shared
/mnt

There are no active volume tasks
nfs.log on GlusterFS servers
shows nothing suspicious (just a
wrong version error, which goes away when manually setting the version when trying to mount).
Tried restarting
nfs-common, rpcbind, stopping and
starting the volume, restarting GlusterFS servers...nothing
makes the volume show up on the client when using NFS.
Again, for clarity, mounting with -t glusterfs works OK, writing and
reading files works.
Thank you
