Full Discussion: RAID 1 + 0 with LVM
Operating Systems Solaris RAID 1 + 0 with LVM Post 93785 by aribault on Thursday 22nd of December 2005 05:25:15 AM

It's quite a long story.
My server has 6 disks 150 GB each but only one controller.
The first operation I did was to mount 3 disks in RAID 5 but the performances were awfull.
That's why SUN recommend me to mount the disks in RAID 0+1 or best in RAID 1+0 with the commands that I posted in my first post. The problem is that RAID 1+0 doesn't work with SVM : the last command metainit d130 1 2 d120 d121 -i 64k fails because it needs physical devices and not logical devices.
Anyway I choosed the solution RAID 0+1 and now it's fine, except that I will need a second controller to improve the performances Smilie .
Thanks again

NAME
ataraid -- software BIOS RAID SYNOPSIS
pseudo-device ataraid ld* at ataraid? vendtype ? unit ? DESCRIPTION
The ataraid driver provides support for BIOS-based software RAID controllers. These are devices which have some simple support for several basic RAID levels (often RAID 0 and RAID 1), but which require software support to actually perform the RAID function. The BIOS support is largely just to create and recognize the array so that it may be a boot device. The driver currently supports RAID formats from: o Adaptec HostRAID (found in Intel 6300ESB) o Intel MatrixRAID o JMicron RAID o nVidia MediaShield o Promise FastTrak o Via V-RAID (found in many VIA-based motherboards) Status of the logical disk as well as the disks associated with it, can be viewed through the bioctl(8) utility. SEE ALSO
ld(4), bioctl(8) HISTORY
The ataraid driver first appeared in NetBSD 2.0. AUTHORS
The ataraid driver was originally adapted from FreeBSD by Jason Thorpe <thorpej@NetBSD.org>. BUGS
Not all features of the software RAID are currently recognized or supported. For example, the Adaptec support doesn't recognize when a RAID 1 should be in a ``building'' state, and it does not do the right thing. At least part of the reason for this is that the publically-available information on these formats is quite limited. BSD
