Hello,
I was just wonder if it's possible to move my RAID5 array to another
distro, same machine just a different flavor of Linux.
Yes.
The only problem will be if it is the root filesystem (unlikely).
Would it just be a case of running:
sudo mdadm --create --verbose /dev/md0 --level=5 –raid-devices=5
/dev/sdb /dev/sdc etc
No
That's kinda dangerous since it overwrites the superblocks (it prompts first).
If you make the slightest error in, eg, the order of the devices (which may be
different under a new kernel since modules may load in a different order etc)
then you'll end up back here asking about recovering from a broken array (which
you can do but you don't want to.)
Or do I need to run some other command.
yes
You want to use mdadm --assemble
It's quite possible that your distro will include mdadm support scripts that
will find and assemble the array automatically.
