I have 3 ceph clusters on nautilus 14.2.9 (same configuration through
puppet). 2 of them are autmatically sharding rados buckets, one of them is
not
When I do
radosgw-admin reshard stale-instances list on the cluster where it does
not work I get:
reshard stale-instances list
Resharding disabled in a multisite env, stale instances unlikely from
resharding
These instances may not be safe to delete.
Use --yes-i-really-mean-it to force displaying these instances.
The other 2 clusters don't give this warning. They are all single site.
The out put of realm list, zonegroup list and zone list for the cluster
that fails auto sharding are as follows
realm list
{
"default_info": "e724bd71-31eb-45c8-a456-151f6a5aa8b5",
"realms": [
"backup"
]
}
zonegroup list
{
"default_info": "ce4329ae-2bc8-4117-9b82-271022b223fa",
"zonegroups": [
"dc3"
]
}
zone list
{
"default_info": "7f9bebd6-a9cf-4006-83b1-ff99391aacc0",
"zones": [
"dc3-r1"
]
}
mgr configuration (default value)
rgw_dynamic_resharding true
How does ceph determine whether it is single site or multi site? How can I
force the automated bucket sharding??
Any help would be much appreciated
Marcel
