Disk Failure

Versions 4.2.2 or 5.1.0
Proxy Cache Mode - Reverse
Cache Disk Type - RAW

What is the expected behavior when a cache disk fails or goes offline for
whatever reason? Is the disk marked as failed/unavailable and ATS continues
to run with the remaining disks?

Thanks!

Do note there is no "--online" option. You will need to restart traffic_server to bring the disk back in to service.
