Description Vincent Milum Jr 2020-07-01 03:47:43 UTC

On AWS, when hot adding an EBS volume to an EC2 instance, FreeBSD doesn't auto-detect the hot-add event.

Manually running "devctl rescan pci0" will detect the newly added device.

Rebooting the instance (which also forces a pci rescan at boot) will also work.

I'm not sure if this was ever fixed for 12.1 -- but it is fixed in 13 at least by https://reviews.freebsd.org/D21948.
