You want to get as many inodes into cache as possible.

Hi,

again with the outlook towards BlueStore.
Bcache [1] allows for block device level caching in Linux. This can be
read/write(back) and vastly improves read and write performance to a block
device.

Hi Dillon,
Ceph uses CephX authentication, which gives permission to users on
selected Pools to read / write. We give mon 'allow r'
to get cluster/Crush map for client.
You can refer to below URL for more information on CephX and creating
user keyrings for access to selected / specific pools.
