Sorry, not aware of this issues. I don't use containers though.
Hello,
recently I thought about erasure coding and how to set k+m in a useful

Hi,
1. two disks would fail where both failed disks are not on the same
host? I think ceph would be able to find a PG distributed across all
hosts avoiding the two failed disks, so ceph would be able to repair
and reach a healthy status after a while?
yes, if there is enough disk space an
For this August Debian testing became a Debian stable with LTS support.
But I see that only sid repo exists, no testing and no new stable bullseye.
May be some one knows, when there are plans to have a bullseye build?
I cannot answer to this question; however I hope that the maintainers

I'll second that. You should have at least k+m+2 hosts in the cluster
for erasure coding. Not only because of redundancy but also for better
distributing the load. EC is CPU heavy.

thanks for the answers. My goal was to speed up the S3 interface, an

Ok - thanks Xiubo. Not sure I feel comfortable doing that without breaking
something else, so will wait for a new release that incorporates the fix. In

What ceph version is used for the cluster ?
Because it looks like (according to the ceph config file) that you're using
either Nautilus/Octopus/Pacific (due to the msgr v2 config)
But are you using the same version for your radosgw node ?
The ceph-common and radosgw packages in buster [1][2] are
This was a bug in some versions of ceph, which has been fixed:
https://tracker.ceph.com/issues/49014
https://github.com/ceph/ceph/pull/39083
You'll want to upgrade Ceph to resolve this behavior, or you can use
size or something else to filter if that is not possible.

So, now I discovered that Debian has it's own ceph packages! For a
stupid joke I added the ceph repository and installed ceph-common
without making an apt clean; apt update; apt upgrade -y and this lead to
