Ceph benchmarking


There are many ways to run a benchmark test on a Ceph cluster to check disk drive, network, and cluster performance. Use the following commands to test the performance of the Ceph cluster.

To write a block of data to test write performance, use the following command:

root@node:/# rados –p <pool> bench –b <blockSize> <seconds> <write> -t <threads> --no-cleanup

To read a block of data to test read performance, use the following command:

root@node:/# rados –p <pool> bench –b <blockSize> <seconds> <seq> -t <threads>

After each of the previous commands, run the following command to clear cache:

root@node:/# echo 3 > tee /proc/sys/vm/drop_caches && sync

We can create a separate pool for the purpose of benchmarking so that we do not run benchmark tests on live production pools. Let us create a pool to run cluster benchmarking using the following command:

root@node:/# ceph osd pool create test 256 256
