    So basically one of my LaCie 2big drives went, I contacted them and they sent me a replacement that I hot swapped. I called them up to have them help me install it, but they are saying with El Capitan, Apple removed the ability to create the raid in disk utility. They gave me instructions on how to do it in Terminal, but they said it would wipe out both drives. (Here are the instructions: http://knowledge.lacie.com/articles/en_US/FAQ/007650en?language=en_US&wwwlocale=en-ca)

    Does anyone know if this is true and if there is anyway I can do this without losing everything? I am currently backing it up to another drive. Just looking for an easier way to do it.

    You could restore Yosemite DU into El-Cap.
    I've done this myself, I renamed Yosemite DU so I could have both versions available when needed.
    My reason for doing this was the same as yours, I needed to manage a raid system I use for TM backups.

    Then we must have a different El Capitan installation. Sure, they have removed the UI fronted, but the terminal command is still there. Again, I have linked you the manual, instructions written there are pretty clear.

    Although the link to the man page is for the 10.9 version of diskutil, the commands involving "repairMirror" have not changed in 10.11.x.

    I don't see instructions? I am afraid I would lose everything on the other drive!
