Hello,
I have two large buckets in my RGW and I think the performance is
being impacted by the bucket index. One bucket contains 9 million
objects and the other one has 22 million. I'd like to shard the bucket
index and also change the ruleset of the .rgw.buckets.index pool to put
it on our SSD root. I could not find any documentation on this issue. It
looks like the bucket indexes can be rebuilt using the radosgw-admin
bucket check command but I'm not sure how to proceed. We can stop writes
or take the cluster down completely if necessary. My initial thought was
to backup the existing index pool and create a new one. I'm not sure if
I can change the index_pool of an existing bucket. If that is possible I
assume I can change that to my new pool and execute a radosgw-admin
bucket check command to rebuild/shard the index.
Does anyone have experience in getting sharding running with an
existing bucket, or even moving the index pool to a different ruleset?
When I change the crush ruleset for the .rgw.buckets.index pool to my
SSD root we run into issues, buckets cannot be created or listed, writes
cease to work, reads seem to work fine though. Thanks for your time!
- Daniel
