Hello everyone,right after finish rebuilding faulty, but still usable, RAID array on Cisco NSS4000 NAS box, array stopped working completly. I took all 4 drives (1TB each) out and connected to my linux machine to take a look what happened. You can find raid-status (mdadm --examine /dev/sd[bcde]) attached.
After reading this page https://raid.wiki.kernel.org/index.php/RAID_Recovery I'm considering to try recreate array, as soon as dd ends with image backup of these drives, but before I screw something I would to ask you RAID wizards for help. Was anyone solving similiar issue?
Thanks for help Jan
