glusterd: remove-brick validation behavior fix

2012-03-31T14:39:00+00:00

earlier one of the major validation case was missed if user provided
a 'replica N' option for remove-brick where N is already existing
replica count of the volume. This would have left the volume in
inconsistent state, eventually crashing glusterd. Now fixed.

cluster/dht: Rebalance will be a new glusterfs process

2012-02-19T09:31:19+00:00

rebalance will not use any maintainance clients. It is replaced by syncops,
with the volfile. Brickop (communication between glusterd<->glusterfs process)
is used for status and stop commands.

Dept-first traversal of dir is maintained, but data is migrated as and when
encounterd.
fix-layout (dir)
do
        Complete migrate-data of dir
        fix-layout (subdir)
done

Rebalance state is saved in the vol file, for restart-ability.
A disconnect event and pidfile state determine the defrag-status

glusterd: Fail volume 'modify' operations when rb is ongoing

2012-02-14T18:22:09+00:00

* add-brick, stop-volume, remove-brick are the operations that are explicitly
 'failed' when attempted while replace-brick is in progress.
* we attach the volume-id to the dst_brick volfile ensuring that the replace-brick
  operation holds 'claim' on it.
