Hey guys,

Is it possible to boot a degraded software RAID5 array when the operating system is installed on the array?

This can be somewhat problematic. Here is a command I found on a forum that successfully booted a Ubuntu degraded RAID system: sudo mdadm --assemble --run --force /dev/md0 /dev/sd[abdefghij]1

Thanks r.  I went ahead and setup a RAID1 array and successfully degraded and then added a drive to it.  

I'd like to have the faster read times and increased storage capability of RAID5 but what I thought would be greater fault tolerance seems to be more problems than it's worth.  

KISS right?

Thanks again.
