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
*) 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
