I try to install XenServer 6.5 with Software-RAID 1 at my home lab. With XenServer 6.2 this setup ran stable for a few months (at the same hardware).
XenServer 6.5 installation went smoothly and boots up without any errors. After enabling the kernel module with
echo "modprobe raid1" > /etc/sysconfig/modules/raid.modules
I followed this guide. Everything went fine until I have to boot from sdb. I can see the XenServer logo (without the loading bar) for a few seconds, then the server screen goes black and a reboot happen.
Does anybody know what went wrong or what I can try to fix the problem?
