Hello, I did an upgrade glusterfs from 3.0.5 to 3.3.1, before I did it, I have other two 3.3.1 hosts(new-host) ready and made a cluster. After I upgraded old hosts, I tried to add them to the cluster, I got State: Peer Rejected (Connected), for sure it could be about same volumes on the old hosts, but I have tried to stop glusterd, remove everything from the old host, such /etc/glusterd, /etc/glusterfs and /var/lib/glusterd/, and start glusterd, then I readded it to cluster, the problem is still there. I also did 'volume sync', but I failed, because of the following error message gluster> volume sync new-hosts please delete all the volumes before full sync I can not do it, or I will lose all my data! The most funny thing I found, even if the peer status is rejected, but I can mount the volume from the old host. Any ideas ! -- Yang Orange Key: 35745318S1 -------------- next part -------------- An HTML attachment was scrubbed...
