Okay, thanks for verifying that bit, sorry to have gone about it so long. I

I followed this documentation:

If it persisted through a full restart, it's possible the conditions that
caused the hang are still present after the fact. The two known causes I'm

Both would show up as processes in "ps aux | grep cephadm" though. The
As you've already seem to have figured out, "ceph orch device ls" is

Sorry for delayed response. This seems to be the limit of assistance I’m

I tried a lot of different approaches but I didn't have any success so far.

I planned to put it on-line. The hold-back is that the main test is un-taring a

Don't know if it helps, but we have also experienced something similar
with osd images. We changed the image tag from version to sha and it did
not happen again.

Hi,
I know the problems that Frank has raised. However, it should also be
mentioned that many critical bugs have been fixed in the major versions.
We are working on the fixes ourselves.
We and others have written a lot of tools for ourselves in the last 10
years to improve migration/update
CEPH configurations can be forced to use multipath but my experience is
that it is painful and manual at best. The orchestrator design criteria
supports low-cost/commodity hardware and multipath is a sophistication

I think with the `config set` commands there is logic to notify the

Curious what happens if the mgr restarts after the `config rm`. Whether it

Hi all,
at Cephalocon 2023, it was mentioned several times that for service
tasks such as data deletion via garbage collection or data replication
in S3 via zoning, it is good to do them on dedicated radosgw gateways
and not mix them with gateways used by users. How can this be achieved?

One of the main reasons - "just can't", because your Ceph-based products will
get worse at real (not benchmark) performance, see [1]
