SOLVED - Mounting an existing RAID set created with mdadm under Debian

Yet another newbie - please forgive me if this has already been asked:

I am interested in converting my Debian system to Arch. However, I have an existing RAID5 set that was created using mdadm under Debian.

If I do a fresh install using Arch, can I mount that RAID set? My guess is that once the Arch system is running I can get the UUID of the RAID set and then use that information to create an fstab entry. Of course I have everything backed up, but restoring would be a lot of work that I prefer to avoid if possible. Alternatively, if there is a better way to manage my RAID set under Arch I would be willing to do a restoration after creating a fresh RAID set.

Any advice?

Thank you in advance

Welcome to the arch linux forums zshlhuppe.  Can you find the RAID set using RAID#Mounting_from_a_Live_CD?

Have you tried just booting to Arch install environment? Unless something has changed with the boot options or something is wrong with the RAID, it should be auto-detected and auto-assembled in a 'soft' read-only state. 'Soft' meaning any action that would involve write will cause it to change to read-write.

My RAID set was visible when I ran "lsblk -fs" from the command line after booting from CD.

I really don't think that I will have any issues mounting my RAID set after I get Arch up and running.

I am new to Arch but not to Linux. 

Thank you both!
