Hi Robert,
Are there known risks to "stepping down" PGs in increments of, say,
10-20% at a time while the cluster is under load?
2.
Reducing the number is best done via halveing not some aribtrary
percentage in order to keep the number a power of 2.
Given the 16k PG count, is there a specific "recovery/backfill"
throttle
we should prioritize to ensure VM performance isn't impacted during
the
merge process?
The performance impact of reducing the number of PGs should be fine.
Regards
