Hi Daniele,

Do you mean that the df -h output is incorrect for the volume post the
upgrade?

If yes and the bricks are on separate partitions, you might be running into
[1]. Can you search for the string "option shared-brick-count" in the files
in /var/lib/glusterd/vols/<volumename> and let us know the value? The
workaround to get this working on the cluster is available in [2].

Thanks for replay. I founded this values

datastore_temp.serda1.glusterfs-p1-b1.vol: option shared-brick-count 2
datastore_temp.serda1.glusterfs-p2-b2.vol: option shared-brick-count 2
datastore_temp.serda2.glusterfs-p1-b1.vol: option shared-brick-count 0
datastore_temp.serda2.glusterfs-p2-b2.vol: option shared-brick-count 0

I need to change the values of serda2 node?!

No, please do not change these files. You need to preform the steps listed

in
https://bugzilla.redhat.com/show_bug.cgi?id=1517260#c19 on your cluster
(copy the shell script, volume set etc). That should fix this.
