Linear Raid OMV died

So decided to switch cases to fit manother HDD in came to boot back up from usb (where OMV is ran from) but getting nothing but the flashing cursor is also the same on another computer so the card is either damaged or FS is broken

Tried a fsck on it and it comes back clean supposdely, now my issue

Stupidly either me or OMV setup a linear raid on 2 drives and obviously because i'm not in the OMV install neither are mountable in linux, is there a way round this (would a reinstall OMV solve it) or is the data potentially gone

seems it was a grub issue, reinstalled a fresh install, removed the raid during install and rebooted with them attatched and there now accessible and working fine

panic over
