Disclaimer: I'm fairly new to Ceph, but I've read a bunch of threads
on the min_size=1 issue as that was perplexing me when I started, as
one replica is generally considered fine in many other applications.
However, there really are some unique concerns to Ceph beyond just the

Hi all,
I am all new with ceph and I come from gluster.
We have had our eyes on ceph for several years
and as the gluster project seems to slow down we
now think it is time to start look into ceph.
I have manually configured a ceph cluster with ceph fs on debian
bookworm.

Advice I added most likely ;) "RAID controllers" *are* a subset of HBAs BTW.

Hello,
I would like to share a quite worrying experience I’ve just found on one of my
production clusters.
User successfully created a bucket with name of a bucket that already exists!
He is not bucket owner - the original user is, but he is able to see it when he
does ListBuckets over s3 api.
I'm currently trying to setup a ceph-dashboard using the official documentation
on how to do so.
I've managed to log-in by just visiting the URL & port, and by visting it
through haproxy. However using haproxy to visit the site results in odd
behavior.
At my first login, nothing loads on the
Hi again,
It turns out that our rados cluster wasn't that happy, the rgw index pool
wasn't able to handle the load. Scaling the PG number helped (256 to 512),
and the RGW is back to a normal behaviour.
There is still a huge number of read IOPS on the index, and we'll try to
figure out what's happ
Hi!
As I'm reading through the documentation about subtree pinning, I was wondering
if the following is possible.
We've got the following directory structure.
/
/app1
/app2
/app3
/app4
Can I pin /app1 to MDS rank 0 and 1, the directory /app2 to rank 2 and finally
/app3 and /app4 to ra

Podman does not come with a daemon to start containers.
The Ceph orchestrator creates systemd units to start the daemons in
podman containers.

Podman doesn't use a daemon, thats one of the basic ideas.
We also use it in production btw.

That's good to know, I have the same in mind for one of the clusters

Hey Ceph-Users,
RGW does have options [1] to rate limit ops or bandwidth per bucket or user.
But those only come into play when the request is authenticated.
I'd like to also protect the authentication subsystem from malicious or
invalid requests.
So in case e.g. some EC2 credentials are not v
