Hi Everyone..

Hi,

There is no option like configuring RAID 1+0 in LVM Terminilogy.

What you can do is you can use Mirror-UX to create exact mirror copies of exising Logical volumes.

You let me know following output:
#model
#swlist |grep -i mirror-ux
As it is different for PA and IA arch.

Regds,

Refer to following :

A very nicely written doc:

Hope this will answer all your queries.

With LVM and Mirror/UX you can do Distributed Extent based striping.

Stripe and mirror by LV extents. This is basically the same as a traditional 0+1 except the stripe size is in MB not KB.

lvcreate -L xx -D y -s g /dev/vgxx

Need to configure /etc/lvmpvg file for PV groups.

Check out the lvcreate man pages for more details.
