I have been trying (and failing) to find a solution to migrate a running system from a default installation of Fedora 4 to a full RAID 1 mirror including mirror of the /boot partition. I attempted to follow the tutorial from:
http://www.linuxdevcenter.com/lpt/a/6553
However the problem is, when you do a default install on 2 HD (80GB) the resulting partition table is like so:
hda1 /boot 102MB
hda2 Volgroup00 76246MB
hdc1 VolGroup00 76348MB
If I to pvmove as per the step in the tutorial I get
# modprobe dm-mirror
# pvmove /dev/hdc1 /dev/hda2
Insufficient contiguous allocatable extents (2) for logical volume pvmove 0:2385 required
Unable to allocate temporary LV for pvmove
I assume this is because hdc1 ia bigger than hda2. So how can i get around this, or do i just have to resign to a complete new install.
