The command "ceph osd pool create ${pool_name} ${pg_number}" is used to create a new Ceph storage pool with a specified name and number of placement groups.

Here's a breakdown of the command:

• "ceph osd pool create": This is the Ceph command used to create a new pool.
• "${pool_name}": This is a placeholder for the desired name of the pool. You need to replace "${pool_name}" with the actual name you want to use for the pool. For example, if you want to create a pool named "my_pool", you would replace "${pool_name}" with "my_pool".
• "${pg_number}": This is a placeholder for the desired number of placement groups (PGs) for the pool. PGs in Ceph are used for data distribution and parallelism. You need to replace "${pg_number}" with the actual number of PGs you want to assign to the pool. For example, if you want to create a pool with 64 PGs, you would replace "${pg_number}" with "64".

By executing this command with the appropriate values, you will create a new Ceph storage pool with the specified name and number of placement groups.
