Gluster users - Jun 2015 - mount with one alive node in replica set

Hello.

I have installation with 2 servers and one volume with type
"Replicate".
Volume mounted on these 2 server
too.

If we turn off one server, another will be work and mounted volume will be
use without problem.
But if we rebooted our another server, when first was turned off (or
gluster was stopped on this server), our volume cann't mount (glusterd
started).
We will be get error "Mount failed. Please check the log file for more
details."


In log for this mount point we will be
see:

In /etc/fstab mount has written
as:

127.0.0.1:/files                            /repo           glusterfs
rw,_netdev              0 0


I found
recomendation:

1. gluster peer probe on localhost by his hostname (or ip). But I get "peer
probe: success. Probe on localhost not needed" and problem preserved.
2. mount by file
like

mount -t glusterfs /var/lib/glusterd/vols/files/trusted-files.tcp-fuse.vol
/repo
or

mount -t glusterfs /var/lib/glusterd/vols/files/files.tcp-fuse.vol
/repo
But it doesn't work
too.



Version of gluster is
3.6.2-3.



How I can get configuration file for mount share/volume from localhost if
other nodes in replica set have down?

If both nodes are down and you bring up only one node, glusterd will not 
start the volume (i.e. the brick, nfs and glustershd processes) 
automatically. It waits for the other node's glusterd also to be up so 
that they are in sync. You can override this behavior by doing a 
`gluster volume start <volname> force` to bring up the gluster process 
only on this node and then mount the volume.
