Thank you in advance.

I've now sent it to the correct maillist this time and in the proper mail format. How does one run fio against an S3 object storage device? Here?s the fio parameters I?m using but I?m getting the below error message: # fio --ioengine=http --iodepth=1 --http_mode=s3 --http_s3_region=us-geo --http_s3_key=123mYkEyInfo --http_s3_keyid=123mYkEyiDinfO --bs=16k --size=100MB --http_host=s3-api.us-geo.objectstorage.inthecloud.net --https=on --http_verbose=2 fio: engine https not loadable fio: failed to load engine Am I missing a kernel module required by fio or am I missing a few more fio parameters from the command line? If so, what do I need to do to enable that module? Here?s my server info: # cat /etc/redhat-release Red Hat Enterprise Linux Server release 7.5 (Maipo) # fio --version fio-3.1 # uname -a Linux mytestserver.testfio.com 3.10.0-862.11.6.el7.x86_64 #1 SMP Fri Aug 10 16:55:11 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux Many thanks in advance for your attention and your response(s).
