Description

When the 12.2.2 balancer module is enabled, it can easily fail without clearly indicating why. After some debugging I discovered that

crush-compat mode requires:

ceph osd set-require-min-compat-client hammer
ceph osd crush set-all-straw-buckets-to-straw2

upmap mode requires:

ceph osd set-require-min-compat-client luminous

Could we document this clearly? or better would be to warn about this before allowing the balancer to be enabled.
