If osd_per_node is unset, then cbt will crash mid way through the run, even with use_existing set to true.

Currently CBT can only instruct fio to run workloads that consist of a single block size. This introduces a way to craft mixed workloads composed of multiple block sizes by...

rbdfio.py should unmap all rbd devices before beginning a run

Adding a clocksource option for fio benchmarks would be useful so that gettimeofday can be selected when there are multiple fio processes running on multiple hosts. Assuming ntp is properly...

Copy ceph.conf and cbt yaml configuration into archive directory, so we have the exact test configuration.

It would be great to have the ability to save the results archive to a S3 bucket instead of it only being on the local filesystem of the head node.

When using use_existing, readahead is not set on the OSDs because they do not have the labels CBT expects. We should probably determine which devices are mounted in /var/lib/osd/\* and...

A cluster composed of nodes with a mix of SSD and HDD, where the SSDs are being used as OSDs, and not for a cache tier. Currently, we can test...
