The currently layout grew and is not very optimal if you have multiple gateways with different usernames/pw/hostnames.

In order to change that some internal structures need to be changed.

Setting that as a TODO!

it'd be helpful to have esxi_ceph_chaos_monkey (eccm) checking data integrity at various stages and layers during a test run:

• application
  • use fio's built in verification functionality, running on the test VM
• guest filesystem
  • use "btrfs scrub" for metadata and data integrity checking
• VMFS
  • use VOMA to check metadata consistency
  • https://kb.vmware.com/s/article/2036767

Each of these would require quite some work. fio verification should be fine as a starting point.

It'd be very useful to be able to compare the performance of clone / migrate across differing Ceph/iSCSI gateway configurations.

IIUC, eccm currently runs until explicitly stopped. It'd be helpful if accepted a test runtime parameter. This should also make post-test cleanup and data integrity checks a little easier to automate.
