Thanks Michael for your response.
Could you also please help in understanding
#1 On my ceph cluster , how can i confirm if journal is on block device partition or on file ?
#2 Is it true that by default ceph-deploy creates journal on dedicated partition and data on another partition if i use the command ceph-deploy osd create ceph-node1:/dev/sdb
I want to understand the concept of journals creation in Ceph. Hope you will help me.

You could mount /dev/sdb to a filesystem, such as /ceph-disk, and then do this:ceph-deploy osd create ceph-node1:/ceph-disk
Your journal would be a file doing it this way.

Subject: Beginners ceph journal question
Hello Cephers
Beginners question on Ceph Journals creation. Need answers from experts.
- Is it true that by default ceph-deploy creates journal on dedicated partition and data on another partition. It does not creates journal on file ??
ceph-deploy osd create ceph-node1:/dev/sdb
This commands is creatingdata partition : /dev/sdb2Journal Partition : /dev/sdb1
In ceph-deploy command i have not specified journal partition but still it creates a journal on sdb1 ?
- How can i confirm if journal is on block device partition or on file ?
- How can i create journal on a file ? command would be helpful ?
RegardsVicky
