Description Amar Tumballi 2011-09-07 11:56:23 UTC

steps to reproduce:

1. create a volume of type 'stripe-replicate' (or 'distribute-stripe-replicate')
2. do a 'gluster peer probe NEW-SERVER'
3. new server's volume is not same as it should be.

Solution:

send 'stripe-count' (which is written as part of volume information in /etc/glusterd/vols/<volname>/info) to peer after the handshake is complete.

CHANGE: http://review.gluster.com/369 (without which, if a peer is added after volume of type 'stripe-replica') merged in master by Anand Avati (avati)

Comment 2 Raghavendra Bhat 2011-09-16 07:32:17 UTC

Its working fine now.

Commands:

gluster volume create new stripe 2 replica 2 10.1.11.73:/export/mirror1 10.1.11.74:/export/mirror1 10.1.11.73:/export/mirror2 10.1.11.74:/export/mirror2
Creation of volume new has been successful. Please start the volume to access data.
[root@Centos1 ~]# gluster peer probe 10.1.11.75
Probe successful
