I'm not sure, but it seems that read and write operations are
performed for all objects in rbd.
If so, is there any method to apply qos for flatten operation?

Hi,
Unfortunately, some of our HDDs failed and we need to replace these drives
which are parts of "combined" OSDs (DB/WAL on NVME, block storage on HDD).
All OSDs are defined with a service definition similar to this one:
```
service_type: osd
service_id: ceph02_combined_osd
service_name:
I think it depends what you mean by rados objects and s3 objects here. If
you're talking about an object that was uploaded via MPU, and thus may
comprise many rados objects, I don't think there's a difference in read
behaviors based on pool type. If you're talking about reading a subset byte

Both methods are not update the mon map, is there a way to inject mon.a001s016

Thank you. I will try the export and import method first.
Thank you,

I have two approaches in mind, first one (and preferred) would be to
edit the mon spec to first remove mon.a001s016 and have a clean state.
Get the current spec with:
ceph orch ls mon --export > mon-edit.yaml
Edit the spec file so that mon.a001s016 is not part of it, then apply:

Hi Eugen,
Yes that is it. OSDs were restarted since mon a001s017 was reporting is low on
available space. How to update the mon map to add mon.a001s016 as it is
already online?
And how to update mgr map to include standby mgr.a001s018 as it is also
running.
ceph mon dump

Maybe it’s just not in the monmap? Can you show the output of:
ceph mon dump
Did you do any maintenance (apparently OSDs restarted recently) and
maybe accidentally removed a MON from the monmap?
Zitat von "Adiga, Anantha" :

Hi Anthony,
Seeing it since last after noon. It is same with mgr services as , "ceph -s"
is reporting only TWO instead of THREE
Also mon and mgr shows " is_active: false" see below.
# ceph orch ps --daemon_type=mgr
NAME HOST PORTS STATUS REFRESHED AGE MEM
> a001s017.bpygfm(active, since 13M), standbys: a001s016.ctmoay
Looks like you just had an mgr failover? Could be that the secondary mgr
hasn't caught up with current events.

Hi
Why is "ceph -s" showing only two monitors while three monitor services are
running ?

I have a single node host with a VM as a backup MON,MGR,ect.

Hello,
I executed multiple 'rbd flatten' commands simultaneously on a client.
The elapsed time of each flatten job increased as the number of jobs
increased, and network I/O was nearly full.
so, I have two questions.
1. isn’t the flatten job running within the ceph cluster? Why is
