Correct, sorry, I have just read the first question and answered too quickly.
As fas as I know the space available is "shared" (the space is a combination of
OSD drives and crushmap ) between pools using the same device class but you can
define quota for each pool if needed.
ceph osd pool set-quota <poolname> max_objects|max_bytes <val> set
object or byte limit on pool
ceph osd pool get-quota <poolname> obtain
object or byte limits for pool
You can use "ceph df detail" to see you pools usage including quota. As the
space is "shared", you can't determine a max size for just one pool (except if
you have only one pool).

You should seek for used and max sizes for images, not pools.
# rbd disk-usage your_pool/your_image
NAME PROVISIONED USED
image-1 51200M 102400k
You can see the total provisioned and used sizes for a whole pool using:
# rbd disk-usage -p your_pool --format json | jq .
{
"images": [
{
"name": "image-1",
"provisioned_size": 53687091200,
"used_size": 104857600
}
],
"total_provisioned_size": 53687091200,
"total_used_size": 104857600
}
A reminder: most ceph commands can output in json format ( --format=json or -f
json), useful with the jq tool.
