Hi list,
Having finished our adventures with Infernalis we're now finally running
Jewel (10.2.11) on all Ceph nodes. Woohoo!
However, there's still KVM production boxes with block-rbd.so being
linked to librados 0.94.10 which is Hammer.
Current relevant status parts:
health HEALTH_WARN
crush map has legacy tunables (require bobtail, min is
firefly)
no legacy OSD present but 'sortbitwise' flag is not set
Obviously we would like go to HEALTH_OK again without the warnings
mentioned maintaining Hammer client support.
Running ceph osd set require_jewel_osds seemed harmless in terms of
client compatibility so that's done already.
However, what about sortbitwise and tunables?
Thanks,
Kees

We're looking at (now existing) RBD support using KVM/QEMU, so this is
an upgrade path.
