Looking at my zones I can see that the master zone (converted from
previously single-site setup) has
bucket_index_max_shards=0
while the other, secondary zone has
bucket_index_max_shards=11
Should I align this and use "11" as the default static number of
shards for all new buckets then?
Maybe an even higher (prime) number just to be save?
Reading
https://docs.ceph.com/en/octopus/install/ceph-deploy/install-ceph-gateway/#configure-bucket-sharding
again,
it seems there are some instructions on editing the zonegroup JSON to
set bucket_index_max_shards to something sensible.
Unfortunately there is no word about this in the mutisite conversion
section
(https://docs.ceph.com/en/octopus/radosgw/multisite/#migrating-a-single-site-system-to-multi-site)
- maybe this would be sensible to ensure folks converting to a multisite
setup don't end up with huge unsharded bucket indices which also cannot
be resharded or even are resharded automatically.
