And sorry to bother you again. Is it possible to create a minimum privilege

Nix the second question, as I understand it, ceph doesn't work in mixed
IPv6 and legacy IPv4 environments.
Still, would like to hear from people running it in SLAAC environments.

Hi Cephers.
Couldn't find any special documentation about the "S3 object expiration" so I assume it should work "AWS S3 like" (?!?) ... BUT ...

Hi,
we are testing Ceph as block storage (XFS based OSDs) running in a hyper
converged setup with KVM as hypervisor. We are using NVMe SSD only (Intel DC

Jason,
do you think it's good idea to introduce a rbd_config object to
record some configurations of per-pool, such as default_features.
That means, we can set some configurations differently in different
pool. In this way, we can also handle the per-pool setting in rbd-mirror.
Thanx

So it indeed seems you are CPU bound at that moment. That's indeed a problem
when you have a lot of map changes to work through on the OSDs.

I suppose the other option here, which I initially dismissed because
Red Hat are not supporting it, is to have a CephFS dir/tree bound to a
cache-tier fronted EC pool. Is anyone having luck with such a setup?

We are facing some performance issue with rados bench marking on a 5 node

As per the PG calculation below is our specification
