Description
At first,my cluster have 6 osds,3 pools which pgnum are all 256 and size are 2,mon_max_pg_per_osd is 300.So ,we need 1536 pgs < 1800.
Then 2 osd disks have bad sector, so we mark them out. To prevent too much pgs for 4 osds, we want to reduce pool size temporarily, but cmd reports a error "Error ERANGE: pool id # pg_num 256 size 1 would mean 1280 total pgs, which exceeds max 1200 (mon_max_pg_per_osd 300 * num_in_osds 4)"
