This is rather odd.
Why are other distributions less supported?

I recall the same story for 3.2 -> 3.3 (or something like that).

I solved it by copying w-vol-fuse.vol to w-vol.vol. Is that enough, or does the current vol file miss some information and I really need to run that command (and restart the cluster actually)?

Thanks,

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).

hi All,

After I rebooted the a cluster, linux clients are working fine.
But nodes cannot mount the cluster.
