Hi,

Yes, the OSDs will periodically scrub the PGs they host based on load

I have a vague memory of this being something that happened in an
outdated version of the ceph tool. Are you running an older binary on
the node in question?

Hi ceph-users team,
I'm a junior systems developer.
I'm developing some applications using librados (librados only rather than
the whole Ceph package) from Ceph and it turns out the work of building the
librados-only package from the huge Ceph source code would be enormous.

The default configuration for a Ceph build should produce a static
rados library. If you actually want to build _only_ librados, that
might require a bit automake tweeks.

At a quick glance, you're probably running into some issues because
you've got two racks of very different weights. Things will probably
get better if you enable the optimal "crush tunables"; check out the
docs on that and see if you can switch to them.

Hello,
I previously created a test cluster using the Argonaut packages available
in Debian testing aka Jessie (atm).
Since it was pointed out to me that I ought to play with something more
recent, I bumped the machines to sid, which has 0.72.2 packages natively.
The sid packages do not include

I don't think nobody has a clue of what you mean.
Ceph is completely written in C++, so there are no Java JARs. The only
piece of Java is the CephFS JNI integration and the RADOS Jav
