I'd like to test how reweighting an OSD will change how the PGs map in the
cluster.
I suspect that I'd dump the CRUSH map and PGs in the cluster that I'm
interested in then use osdmaptool. I'm not understanding how to use
osdmaptool to set the reweight, then query a PG or the entire set of PGs
that I'm interested in. I then suspect that if I'm okay with the new map
that I could inject it into the cluster instead of having to run reweight
on the OSD(s).
This is a Jewel cluster and I'm trying to calculate OSD usage offline, then
inject a map that is more distributed instead of doing a reweight, move the
PGs which take a long time to just rinse and repeat over and over again.
Thanks,
Robert LeBlanc

Hi,
see https://tracker.ceph.com/issues/41660
ceph-volume lvm activate --all fails on the second OSD when stderr is
not a terminal.
Reproducible on different servers, so there's nothing weird about a
particular disk.
Any idea where/how this is happening?
This makes 14.2.3 unusable for us as we need to re-activate all OSDs
after reboots because we don't have a persistent system disk.

Hi,
I try to build Ceph v13.2.6 locally and I was clone and checkout with
v13.2.6 tag.
I run ./run-make-check.sh but it's failed. It's shows below error
