Hi Community,
I recently proposed a new authorization mechanism for RGW that can let the
RGW daemon ask an external service to authorize a request based on AWS S3
IAM tags (that means the external service would receive the same env as an
IAM policy doc would have to evaluate the policy).

I found a way to set it using:
ceph-kvstore-tool rocksdb . set osdmap first_committed ver 12261
But is that safe to do it? =)

Hi,
I've lost all my mon dbs and after rebuilding it using OSDs the osdmap
first_committed is set to 1 but my osdmaps commits start from 12261 (get a

fail because it can't find osdmap 1.

The way I want to unset is to decompile osdmap remove this flag and compile
it again and set it to Ceph.

Hi. I found a default rocksdb option in bluestore that I can't find in
facebook rocksdb.
recycle_log_file_num this config if a boolean config in facebook
rocksdb but in default Ceph configs the value of this is 4.
Can someone tell what it means?

Hi all.
Is there any way that I could calculate how much time it takes to add
OSD to my cluster and get rebalanced or how much it takes to out OSD
from my cluster?
Thanks.
