Subject: osd/OSDMap: apply both pg_upmap and pg_upmap_items
X-Git-Tag: v12.1.1~81^2~5
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=379e47e1444ba47f89ee065f708dddbcaf4c5040;p=ceph.git

osd/OSDMap: apply both pg_upmap and pg_upmap_items

This allows a more flexible upmap policy by combinating
both pg_upmap and pg_upmap_items.

For example:
./bin/ceph osd pg-upmap 1.0 1 2 3
set 1.0 pg_upmap mapping to [1,2,3]

./bin/ceph osd pg-upmap-items 1.0 1 5
set 1.0 pg_upmap_items mapping to [1->5]

 ./bin/ceph pg ls-by-pool cephfs_data_a
