We have seen the same problems 8 years ago. I can only recommend never

Hi,

pg_autoscaler in the last years.

The commands:
ceph osd reweight-by-utilization
ceph osd test-reweight-by-utilization
are from the time before the upmap balancer was introduced and
Another the possibility is also the ceph mon discovery via DNS:

Hi,
short note if you replace the disks with large disks, the weight of the
osd and host will change and this will force data migration.
Perhaps you read a bit more about the upmap balancer, if you want to

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

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
"bucket does not exist" or "permission denied".
Had received similar error messages with another client program. The default
region did not match the region of the cluster.
