Metadevices in mirroring ?

Hi Guys.

I have the follow disk mappig....

My doubt is that the filesystem root is in mirroring. I can see this in the configuration but , I dont know exactly if this in mirroring mean disk in RAID.

In short: Watching the configuration...Can I said if the filesystem / is in Raid?

Thanks in Advanced,
AGAD

by your configuration I can say that / is mirrored. I can't tell if everything is configured correct and the mirror is working... that can only be said after proper testing!

Configured on mirroring = Configured on RAID ?
