Description

Problem:
I have a small cluster at home and I noticed that during the upgrade from 12.2.5 -> 12.2.7 and the upgrade from 12.2.7 to 13.2.1 the upmap settings are forgotten when restarting the OSDs.

Expected behavior:
Upmaps are remembered so they don't have to be re-applied after each OSD restart.

Additional notes:
Originally I created the upmaps with the balancer, but because of this problem they are now set using 'ceph osd pg-upmap-items' like this:

ceph osd pg-upmap-items 5.38 10 18
ceph osd pg-upmap-items 5.d 2 18
ceph osd pg-upmap-items 5.21 11 18
ceph osd pg-upmap-items 5.48 2 18
ceph osd pg-upmap-items 5.3d 11 18
ceph osd pg-upmap-items 5.14 5 18
ceph osd pg-upmap-items 5.1 11 18 8 6 9 0
ceph osd pg-upmap-items 5.f 11 18
ceph osd pg-upmap-items 5.3 10 6 11 0
