Ceph: Designing and Implementing Scalable Storage Systems

How to do it...

To benchmark the Ceph Block Device, we need to create a block device and map it to the Ceph client node:

1. Create a Ceph Block Device named block-device1, of size 10 G, and map it:

        # rbd create block-device1 --size 10240 --image-feature layering        # rbd info --image block-device1        # rbd map block-device1        # rbd showmapped

2. Create a filesystem on the block device and mount it:

        # mkfs.xfs /dev/rbd1        # mkdir -p /mnt/ceph-block-device1        # mount /dev/rbd1 /mnt/ceph-block-device1        # df -h /mnt/ceph-block-device1

3. To benchmark block-device1 ...
