restore degraded mdadm raid from previous install!

as per the title really… I’d like to bring online a 4 disk raid10 mdadm array, with 1 drive missing from a previous install (ubuntu 12.04.1), onto my new opensuse 12.3 home server. I have the original config (fdisk -l) so i know how the partitions were laid out. Am i able to follow one of the many “bring degraded mdadm back online” guides out there, or is there something something special i need to consider since I’m moving between kernels/distros?

Don’t know why you haven’t had a reply yet, sorry for that …

There’s nothing special to consider really. the mdadm formats etc are
independent of kernel version and distro.

Just pick one of the how-tos that you like, double check against a
second and against the man pages/wiki and have a go. Come back here if
there’s something that looks suspicious.

Try to use read-only commands for a start, and ensure you have a backup
first, of course (RAID doesn’t remove the need for backups).
