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
