I've been using OMV since it was first released, and while i've had a couple of issues, nothing like this before,it's generally been rock solid.
My setup consists of a HP Microserver with 4x HDD in the SATA slots, and OMV booting off a USB key installed in the internal USB slot.
Over the last month I have burnt through 3 USB keys. WHen the first one went I was like 'oh well'. When the second one went days laters I was thinking I was unlucky. When the third one died I figured I should try a new tactic.
I am now trying install OMV onto a USB HDD. I run the setup, and it goes through fine. However after install, it drops to the grub screen.
I am installing from a USB thumb drive to the USB HDD.
The device I install to is /dev/sda during installation.
Checking /boot/grub/devices.map has the correct drive listed as HD0.
When it drops to grub after install and reboot, i try to manually boot (linux /boot/vmlinuz... then initrd /boot/init.rd..... then boot) but that fails with an whole heap of errors (e.g mount:mounting /sys on /root/sys failedL No such file or directory)
If I run a rescue install, and get it to re-install grub, or run a grub-mkconfig, then it makes it even worse, dropping into grub-rescue mode on boot.
Any suggestions / thoughts would be much appreciated.
