Description of problem: Only 1 replace-brick can be active for a volume. The action in itself typically takes days, so when lots of bricks have to be replaced this is a very lengthy process. Adding support for multiple replace-bricks running in parallel would greatly help. Version-Release number of selected component (if applicable): 3.2.5, 3.3.1 How reproducible: Start a replace-brick. Now try to start a second one. Steps to Reproduce: 1. gluster volume replace-brick vol-a b c start 2. gluster volume replace-brick vol-a d e start Actual results: Step 2 cannot run when step 1 is still active. Expected results: Step 2 can run. Additional info:
Additionally it would be very nice if add-brick would work while replace-brick is active.
This is request for a new feature/enhancement. Added the [FEAT] field in the summary
Feature requests make most sense against the 'mainline' release, there is no ETA for an implementation and requests might get forgotten when filed against a particular version.
because of the large number of bugs filed against mainline version\ is ambiguous and about to be removed as a choice. If you believe this is still a bug, please change the status back to NEW and choose the appropriate, applicable version for it.
