Hi, To support add/remove brick on tiered volumes we are planing to separate the tier into a separate process in the service framework and add the add/remove brick support. Later the users will be able to spawn rebalance on tiered volumes (which is not possible). The following are the steps planed to be performed: *) tier as a service (final stages of code review) *) we are separating the attach tier from add brick and detach from remove brick. *) infra to support add/remove brick. *) rebalance process on a tiered volume. *) a few patches to take care of the issues that will be arising eg: while adding a brick on a tiered volume, the tier process has to be stopped as the graph switch occurs. and other issues like this. The whole volume expansion will be in an experimental state. while the separation of tier into a separate service framework and attach/detach tier separation from add/remove brick should be back to stable state before the release of 3.10 [1] https://github.com/gluster/glusterfs/issues/54 -- Regards, Hari. _______________________________________________ Gluster-devel mailing list Gluster-devel@xxxxxxxxxxx http://www.gluster.org/mailman/listinfo/gluster-devel
