db_size doesn't work when use pvecehp createosd

[Lyons WANG]

sda is hdd and sdb is ssd, when use pveceph createosd, but -db_size doesn't work,here is the report

root@pve-03:~# pveceph createosd /dev/sda -db_dev /dev/sdb -db_size 10
create OSD on /dev/sda (bluestore)
creating block.db on '/dev/sdb'
'/dev/sdb' is smaller than requested size '1000083134873' bytes

Am I wrong? the pveceph docs says as follows:

You can directly choose the size for those with the -db_size and -wal_size paremeters respectively. If they are not given the following values (in order) will be used:

• bluestore_block_{db,wal}_size from ceph configuration…
  • … database, section osd
  • … database, section global
  • … file, section osd
  • … file, section global
• 10% (DB)/1% (WAL) of OSD size

my version is pve 6.0 with ceph nautilus, and sda and sdb infos:

root@pve-03:~# parted /dev/sda print free

This is 1 TB as size, but sdb has only 480 GB. The db_size and wal_size are in GiB.
