I need to migrate a old 2 node cluster to a proxmox cluster with a replicated gluster storage between those two (and a third arbitrer node). Id like to create a volume with a single node, migrate the data on this volume from the old server and then reinstall the second server and add the second brick to the volume.
If you have only 2 nodes in total, you may lower replica to replica 1, reinstall another node, re-add bricks to form replica 2 and repeat these steps for another node. No downtime and data migration by hands needed.
I found no informations about creating a replicated volume with a single node, is it possible ?
Yes, with "force" option, if you really need that.
Also is it possible to add a third arbitrary node to an existing 2 replica volume ?
Yes, starting from v3.8. Regards, Oleksandr _______________________________________________ Gluster-users mailing list Gluster-users@xxxxxxxxxxx http://www.gluster.org/mailman/listinfo/gluster-users
