Hm, I set that to 1 now, and nothing changed:
$ ceph osd lspools
0 data,1 metadata,2 rbd,
$ ceph osd pool set data min_size 1
set pool 0 min_size to 1
$ ceph osd pool set rbd min_size 1
set pool 2 min_size to 1
$ ceph osd pool set metadata min_size 1
set pool 1 min_size to 1
$ ceph -s
health HEALTH_WARN 384 pgs degraded; 384 pgs stuck unclean; recovery
1552/3104 degraded (50.000%)
monmap e1: 1 mons at {alpha=x.x.x.x:6789/0}, election epoch 1, quorum 0
alpha
osdmap e16: 1 osds: 1 up, 1 in
pgmap v104: 384 pgs: 384 active+degraded; 6112 MB data, 7144 MB used, 456
GB / 465 GB avail; 1552/3104 degraded (50.000%)
mdsmap e14: 1/1/1 up {0=a=up:active}
Are you sure this is a different setting than what you can see and change in
the crushmap? Because that would be quite confusing...
