Hi,
with the restart I have looked on an non-pve-host. on pve it's someting like:
there are two numbers - the higher one is the right one.

that is it. it is perfectly OK to need to do that. i've seen requests that it b automated, i do not know how to code that, i'm sure the devs are working on other things .
PS: do you eat pork/bacon pork chops? or love pigs as pets . I know a group of hunters out shooting for pork chops and could send some along with bread for the help

Glad I could help.
BTW, you didn't actually need to build a new pool to increase the number of Placement Groups after adding OSDs. You can always increase the number of placement groups in a pool - you just can't decrease them. You also can't do it inside the Proxmox GUI, at least AFAIK.
From the command line: Ceph odd pool set <pool_name> pg_num <new PG value>.
As for your last question - I just think pigs are cool.

I have baby sat for a friends pig pet. it was the best couch cleaner we ever had. my kids would drop food in couch. dogs are ok for floor. pigs can dig deep and eat .
the move works now.
So I'll need to remember to do the key thing. storage is so much easier then the old days. fdisk , mkfs* .
Udo - thanks for the tips.
i'll make admin ceph notes wiki sub page.
question: so I plan to have 2 pools
do my page group calculations seem OK? I'll be doing the changes overnight.:
I'll have 2 pools:
size/min 3/1 : data
2/1: appliances and LAN data backup.
for 10 OSD's 3/1 placement group calculation.
I thinkk we need 512 PG for 3/1 10 OSD:

Code:
Replicas: 3/1
osd pool default size = 3
osd pool default min size = 1
10 * 100 / 3 = 333 ,
power of 2 round up = 512 . # https://en.wikipedia.org/wiki/Power_of_two
