Hi David,
I am Praveen, we also had a similar problem with hammer 0.94.2. We had the
problem when we created a new cluster with erasure coding pool (10+5
config).
Root cause:
The high memory usage in our case was because of pg logs. The number of pg
logs are higher in case of erasure coding pool

If the downtime is related to a problem with a ceph cluster, it should

cause a downtime of multiple days.
Usually thats quiet long for a productive usage.
So any information with some details is highly a
When you increase your pg number, the new pgs will have to peer first and
during this time they will be unreachable.So you need to put the cluster in
maintenance mode for this operation.
The way to upgrade the number of PG and the PGP of a running cluster is :

Hello,
I have a huge RGW bucket with 180 million objects and non-sharded

I wonder is it safe to delete it with --purge-data option? Will other
buckets be heavily influenced by that?

Hello everyone,
We are in the process of buying hardware for our first ceph-cluster. We
will start with some testing and do some performance measurements to
see that we are on the right track, and once we are satisfied with our
setup we'll continue to grow in it as time comes along.
Now, I'm jus

Hi,
I had experience with deleting a big bucket (25M small objects) with
--purge-data option. It took ~20H (run in screen) and didn't made any
significant effect on the cluster performance.

Restarting OSDs does not change the memory usage.
