Intallation with Raid 1, LVM and Syslinux

https://bbs.archlinux.org – I am doing raid 1 on the same disk (not very good but better that doing no raid)  So, I followed the instructions but doing them on the same disk (except install MBR on only one disk) and I obtained the message at the boot :Multiple active partitionsAfterwards, I removed the boot flag on the second partitions making the raid 1 array, the new message isBooting...Missing OS  Is it really possible to boot on a raid 1 array with 2 partitions on the same disk ?

Stories similar to Intallation with Raid 1, LVM and Syslinux

I have a 5-disk Intel RAID 5 along with a 6th boot disk with /, /boot, and swap.

What I was planning to do was mount the Intel RAID partitions (which I've added with fdisk) so that the 6th disk /home, /var, /srv, etc. link to the RAID on the other 5 disks.

I am trying to setup a raid 5 but when I do the boot block causes the first disk to go to extended when the rest do not have to. This then leaves me with one on extended and three not. That would be fine but then the raid 5 will not recognize the extended so I end up with raid 5 -1 for part of the array. I am thinking that if I could designate 0 to 25 on each disk that all will be well.

A friend's machine running Windows XP refused to boot recently which is running 3 SATA disks on RAID 5 (which was previously upgraded from RAID 1 not by me). I have determined there to be a disk failure. The disks have been replaced many times in the past few years. I wish to backup the RAID5 partition before I try anything to fix it.

I don't really know what I'm doing here, but I'll describe the situation:Intel RAID card supporting 2 RAIDS A 2 disk RAID 0 for the system A 5 disk 10 TB RAID 5 for storage

LVM laid on top of the RAID 0 to partition it All has been well for months updated (yum update), didn't track what got upgraded On reboot, partitions aren't found.

After adding a new disk to your raid chain it’s a good idea to make it bootable as well by installing grub on MBR.

Hoping someone can help...

Here is my setup:

4x Western Digital 1TB drives - 200GB RAID 0 (Windows 7 and Apps / Games) - 1.8TB RAID 10 (Data)

Both arrays use all 4 disks.

Ubuntu has its own 80GB drive (/dev/sde).

After having experienced (again) disk failures with my md/raid5 system, I reinstalled my system (openSuse 11.2) on a new 1 TB drive (raid-less). Now, after having new disks for setting up my md-raid again, I would prefer not to start over again, but to transfer my running system onto these to-be-built md-raid arrays.

I have a raid 5 array constructed of three partitions, one of which is another array. This array should be assembled during boot so that it can be mounted and other services can access the mounted data.

[64 bit] Raid 1 Rebuild 42 weeks 2 days ago

I'm running 10.04 LTS Desktop 64bit, with two identical disks set up as a raid 1 array. Last week I kicked the power lead from the back of the PC Using the rescue disk to repair grub, I can now boot from sda2 mounted at /, while sdb2 seems OK but not mounted.
