Run DAOS Autotest

DAOS autotest tests the proper setup of the DAOS configuration, which is used to test the setup. DAOS autotest performs various activities like connecting to a pool, creating and opening a container, then reading and writing to the container.

First of all, a pool must be created with dmg to run autotest:

$ dmg pool create --size=50G autotest_pool

# sample output
Creating DAOS pool with automatic storage allocation: 50 GB NVMe + 6.00% SCM
Pool created with 6.00% SCM/NVMe ratio

  UUID          : 6af46954-f704-45f0-8b80-115ef855a065
  Service Ranks : [1-3]
  Storage Ranks : [0-3]
  Total Size    : 53 GB
  SCM           : 3.0 GB (750 MB / rank)
  NVMe          : 50 GB (12 GB / rank)

Then run autotest via the daos utility:

$ daos pool autotest autotest_pool
