glusterd: Brick process fails to come up with brickmux on
Issue: 1- In a cluster of 3 Nodes N1, N2, N3. Create 3 volumes vol1, vol2, vol3 with 3 bricks (one from each node) 2- Set cluster.brick-multiplex on 3- Start all 3 volumes 4- Check if all bricks on a node are running on same port 5- Kill N1 6- Set performance.readdir-ahead for volumes vol1, vol2, vol3 7- Bring N1 up and check volume status 8- All bricks processes not running on N1. Root Cause - Since, There is a diff in volfile versions in N1 as compared to N2 and N3 therefore glusterd_import_friend_volume() is called. glusterd_import_friend_volume() copies the new_volinfo and deletes old_volinfo and then calls glusterd_start_bricks(). glusterd_start_bricks() looks for the volfiles and sends an rpc request to glusterfs_handle_attach(). Now, since the volinfo has been deleted by glusterd_delete_stale_volume() from priv->volumes list before glusterd_start_bricks() and glusterd_create_volfiles_and_notify_services() and glusterd_list_add_order is called after glusterd_start_bricks(), therefore the attach RPC req gets an empty volfile path and that causes the brick to crash. Fix- Call glusterd_list_add_order() and glusterd_create_volfiles_and_notify_services before glusterd_start_bricks() cal is made in glusterd_import_friend_volume Change-Id: Idfe0e8710f7eb77ca3ddfa1cabeb45b2987f41aa Fixes: bz#1773856 Signed-off-by: Mohammed Rafi KC <rkavunga@redhat.com>
