[Gluster-users] cannot fuse mount from a cluster node

[Kaushal M]

This is a known issue non RPM (Fedora/EL) packages. The DEB packages and
packages for other distros don't do a post upgrade regeneration of
volfiles. So after the upgrade, GlusterD is searching for the new volfiles
which don't exist, and cannot give the clients with a volfile, leading to
the mounts failing.

You can look at https://bugzilla.redhat.com/show_bug.cgi?id=1191176 for
more details.

tl;dr stop glusterd, run `glusterd --xlator-option *upgrade=on -N` to
regenerate the volfiles, start glusterd (on all nodes).
