Rados bucket issues, default.rgw.buckets.index growing every day

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

I have some issues with my bucket index. As you can see in the
attachment, everyday around 16:30, the amount of objects in the
default.rgw.buckets.index increases. This happens since upgrading from
12.2.2 to 12.2.4.

There is no real activity at that moment, but the logs do show the
following:

rgw.log.1.gz:2018-04-03 16:28:24.594527 7fad2e13d700  0

I have dynamic bucketsharding enabled, and there is a reshard entry,
but because I use tenant and rados had a bug where it didn't add tenant
to the reshard-log, that entry is invalid. The bucket it mentions
doesn't even exist anymore.

So. How do I find out who is creating all these entries in the index,
and why. Secondly, how do I remove the reshardingentry for a bucket
that does not exist? I have a strong feeling that the two questions are
very much related, because of https://tracker.ceph.com/issues/22046

Thanks,

Mark
