I've been reading a lot about the mdadm tools lately, and I believe tha= t it is possible, but I haven't found the right documentation yet. Is it possible to re-mount the RAID I have from another Linux installat= ion? Do I need more than the 'mdadm --detail --scan > /etc/mdadm.conf' = info saved to another location (so I can re-import it)?
