Disk for Ceph Journal

[D.P.]

Hi,
I have 3 node Proxmox cluster. I want create Ceph storage.
Every node has 5 disks: one SSD for Ceph Journal (sdb) and four for OSD (sdc,sdd,sde,sdf).
Should I create partitions on SSD (sdb) for every OSD disk and:
# pveceph createosd /dev/sd[c-f] -journal_dev /dev/sdb[1-4]
or point all OSD at one disk:
# pveceph createosd /dev/sd[c-f] -journal_dev /dev/sdb

Hi,
every OSD need they own journal - mean use partitions.

What type of partition should be set? Linux or other.
