hi all.
I recently updated my Kurnel and rebooted my Helios64. when it loaded in to OMV i noticed my raid drive is missing. i can still see the disks just not the raid drive . Checking on the array i can see it failed with an error 524.
Would love some suggestions on how to repair the array.
below is the details i was able to get,.. sorry for the large info dump
