[dundee] Ubuntu Install RAID 1 + LVM is a no go..

[Lee Hughes]

Okay, so software raid is cool , and I can see it's advantages over hardware raid..

but

If I install an ubunutu machine, I go through manual partitioning, and set up a raid 1
mirror (using two disks). If I then tell lvm to setup on that drive (raid device 0), the
install then tried to parition the md device into two parts, a ext3 /boot and the rest
as lvm.

as we all know you can't partition raid devices, so them comes meltdown.

I've tried to be clever too and create two raid device 1, for /boot and 1 for the lvm
but the install just tried to partition again...

???????????????

I presume you've all set up raid and lvm *after* the initial install of the o/s

enlighten me!!

Absolutely, I use Linux's software RAID at work.

A 466GB RAID 5 (3 disks) and a 2.3TB RAID 5 (8 disks, 6 in use, 2 spare)

Been stung by hardware RAID in the past.
