ada disk now da disk in upgrade to 10.2 Release?

[John Howie]

Hi all,

I ran an upgrade via freebsd-update from 10.1-RELEASE to 10.2-RELEASE. Everything went well until the reboot after kernel updates. The kernel complained it could not find the root filesystem, which was at /dev/ada0p2. The disk no longer appears in /dev, and it is now /dev/da0p2.

The machine is running under Hyper V (a guest OS).

Does anyone have any idea why this might have happened?

Regards,

John
