Hi,
Can someone please assist met with some software RAID 1+0 setup instructions? I have searched the web, but couldn't find any. I found a lot of RAID 10 setup instructions, but it doesn't help me.
Hi Rudi RAID 10 and RAID 1+0 are the same thing.
See here: http://en.wikipedia.org/wiki/Nested_RAID_levels#RAID_10_.28RAID_1.2B0.29 or here: http://en.wikipedia.org/wiki/Non-standard_RAID_levels#Linux_MD_RAID_10
Hi Oliver,
It's not the same thing :) Although they work, and do the same, the installer CD & mdadm needs to support it. The specific appliance that I want to install, doesn't support RAID 10, so I need to install RAID 1 + RAID 0, i.e. setting 2x RAID 1 mirrors, and then stripe then in RAID0 - but once the first 1 mirrors are setup, I can't stripe them.
I've seen people use LVM to add them to one volume, but the installer doesn't see to like that either.
