>Description:
When using a rootserver (MSI K8T Neo 2 V2 Mainboard with VIA VT8237 Chip) with a configured raid 1 (/dev/ar0) - you might not want to do an upgrade to freebsd 8.0-RELEASE like described here: http://www.daemonology.net/blog/2009-07-11-freebsd-update-to-8.0-beta1.html

You wont have any problens installing the kernel, userland and 3rd party apps - but after the last reboot the box fails with the message "Fatal Error Occured, Raid relationship and Content of all hdds ill be DESTROIED - Continue (C)"  (Yes, with that typo).

I doublechecked everything and repeated the whole procedure twice. After recovering my lost partitions, i found out that the fstab changed from /dev/ar0 to /dev/ad4 and /dev/ad6 somewhere during the upgrade process. This may be a lead to the problem.

As I am just a user and not a skilled bsd admin, I am sorry if this issue is already known or may just be a result of my lack of knowledge.




>How-To-Repeat:
Upgrade just like written above using the same hardware...
>Fix:
no fix known... reverted to 7.2
