Use cases for plankton-swarm

[laimis9133]

Starting a thread just to show off some examples where this small manual balancer can be used.
Feel free to add, I'm just sharing where have used it succesfully.

Use it as a regular hourly cron to balance out any overfilling OSDs. Keep a balancer log to review.
0 */1 * * * plankton-swarm.sh source-osds gt85 all target-osds lt75 pgs 2 >> balancer.log 2>&1 && bash swarm-file

When replacing disks or whole nodes, use it to move additional data once degraded backfilling completes.
0 */3 * * * plankton-swarm.sh source-osds top 10 target-osds osd.1,osd.2,osd.3 pgs 5 >> balancer.log 2>&1 && bash swarm-file
I know I know - CRUSH weights could do that for you.
