[Gluster-users] Growing cluster: peering worked, staging failed

[Andreas Schwibbe]

Solving my own issue:

Staging fails due to checksum error.
Checksum error occurs, when you try to upgrade a cluster with option
nfs.disable set as this is made optional in gluster 11
You have to upgrade the whole cluster to 11, then peer probe is
successful as nfs.disable option is removed during upgrade on all nodes
resulting in matching checksums.
Unfortunately this means no online upgrade procedure 😕
Findings, errors etc. documented in this
issue: https://github.com/gluster/glusterfs/issues/4386

Cheers,
A.
