[Gluster-users] mount failing client to gluster cluster.

[Amar Tumballi]

Hi,
On a debian 9 client,
========
8><---
ii glusterfs-client 3.8.8-1 amd64
clustered file-system (client package)
=======
I am trying to to do a mount to a Centos 7 gluster setup,
=======
glusterfs-4.0.2-1.el7.x86_64
=======
mount -t glusterfs glusterp1.graywitch.co.nz:/gv0/kvm01/images
/var/lib/libvirt/images

I see that you are trying 'subdir' mount. (as I see '/gv0' was able to
mount fine).

If that is the case, please make sure to add a proper 'auth.allow' entry
for subdir.

something like 'gluster volume set gv0 auth.allow "/(*),/kvm01/images(*)"

But, while typing above, noticed that subdir mount is enabled by default
for every directory if none of the options are given. So, looking deeper, I
see below line in your client:

[2018-05-08 03:33:48.989219] I [MSGID: 100030] [glusterfsd.c:2454:main]
0-/usr/sbin/glusterfs: Started running /usr/sbin/glusterfs* version 3.8.8*
(args: /usr
/sbin/glusterfs --volfile-server=glusterp1.graywitch.co.nz
--volfile-id=/gv0/kvm01/images/ /var/lib/libvirt/images)

and for that version, we didn't had that particular feature.

the logs are telling me,
=========
libvirt-images.log
/gv0/kvm01/images/ /var/lib/libvirt/images
Mount failed. Please check the log file for more details.

though,
mount -t glusterfs glusterp1.graywitch.co.nz:/gv0 /isos
works fine.

also, I can mount the sub-directory fine on the gluster cluster itself,

Is this a version mis-match thing? or what am I doing wrongly please?
