I've been looking around for example /etc/raidtabs and only seem to find
ones that look like this:
raiddev /dev/md0
raid-level 1
nr-raid-disks 2
nr-spare-disks 0
chunk-size 4
persistent-superblock 1
device /dev/sda1
raid-disk 0
device /dev/sdb1
raid-disk 1
My question is, considering that I have multiple partitions that I want to
array and I also want to boot from my RAID 1 array, can I just do this?
device /dev/sda
raid-disk 0
device /dev/sdb
raid-disk 1
or do I need to do this?
device /dev/sda1
raid-disk 0 device /dev/sda3 raid-disk
0 device /dev/sda5 raid-disk 0 device
/dev/sda6 raid-disk 0 device /dev/sdb1
raid-disk 1 device /dev/sdb3 raid-disk
1 device /dev/sdb5 raid-disk 1 device
/dev/sdb6 raid-disk 1Any assistance would be greatly
appreciated.

I realize that the example below is ugly, sorry for that :(
Basically what I'm asking is, can't I just specify /dev/sdX in raidtab or do
I actually have to specify each and evry single partition on the disk for
the array to work - i.e., /dev/sdX# ????
Please see below if you can deal with the lousy formatting.

You have to specify each partition.
