That guide didn't help me, ran into a problem:
Run sudo mdadm --assemble --scan
receive : mdadm: No arrays found in config file or automatically.
Been searching around the net and came across this thread http://forum.cgsecurity.org/phpBB3/syno ... -t386.html
edit:
I've since booted back up the NAS and been working from SSH. I've found what i guess is my volume config backup /etc/lvm/backup/vg1000 and i was able to see all the info on each of my drives running mdadm --examine /dev/sd on each disk a1, a2, b1, b2... ect.
Anyone have any ideas on how to restore my volume?
