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.
