This is a 18.2.4 reef cluster Looking for help with cloud sync module. Here is my setup
1. Two Ceph clusters with RGW setup in a MultiSite configuration. There is no
data synchronization between the clusters. No data sync groups, flows, or pipes.
2. We use a multi tenant setup with a small number of tenants (10). We have one
tenant that is writing to the same bucket in different rgw zones. The names of
files are unique in each zone.
3. We are using the cloud-sync module to copy data from our ceph clusters to
aws. I have pasted the commands used to create the sync zone
The cloud-sync module works but for one issue that I can not figure out. For
some reason another bucket in another tenant is showing up as target to sync
but was never specified in the original config. I can never get a clean
radosgw-admin sync status because there are recovering shards from a bucket in
another tenant that I never intended to sync to the cloud.
The data sync status of the recovering shard is pointing to a bucket that never
had any cloud sync specified. tenant1/bucket1 was never part of any tier config.
radosgw-admin sync error list --rgw-zone cloud-sync shows a never ending list
of objects that can not be synced from tenant1/bucket1 there are 4 different
types of error messages.
"message": "failed to sync bucket instance: (22) Invalid argument"
"message": "failed to sync bucket instance: (39) Directory not empty"
"message": "failed to sync object(16) Device or resource busy"
"message": "failed to sync object(39) Directory not empty"
One other point is that radosgw-admin sync info --rgw-zone cloud-sync --bucket
tenant1/bucket1 seems to indicate that that is part of the
cloud-sync config.
What I just want to do is remove tenant1/bucket1 from the sync config and stop
the data sync such that the shards recover and the error log stop
accumulating messages. I would really like a clean sync status for my cloud
tier zone. It would also be nice to help understand what is happening here.
All and any help is greatly appreciated.
