Does Red Hat Enterprise Linux supports Software RAID 10?

Solution Unverified - Updated -

Issue

  • Would like to know if software raid 10 is supported and if yes, how to create one?
  • How do I create software RAID 10 in RHEL using mdadm command?
  • What steps involved to create software RAID 10 in RHEL 6, how to create it?
  • Are nested MDRAID devices supported in RHEL 6? We have 6 HDDs (sdb,sdc,sdd,sde,sdf,sdg) all drives are 200GB SSD’s. Imagine there are 3 RAID1 devices:
md2 (sdb1,sdc1) 
md3 (sdd1,sde1)
md4 (sdf1,sdg1)
  • and there is md10 = RAID 0 build on the top of (md0,md1,md2) so we have nested RAID using mdadm /dev/md10 --create -c 256 --metadata=1.1 --level=stripe --raid-devices=3 /dev/md2 /dev/md3 /dev/md4?

Environment

  • Red Hat Enterprise Linux(RHEL) 5/6
