  I also did this way for my cluster, BUT I've experienced instability
for some nodes (3/4 over 20). My guess was that "cp /dev/hda /dev/hdb"
copied also the bad-blocks list of hda onto hdb and this looks wrong
to me. So I partitioned and made the filesystems on each node and then
cloned the content of each filesystem. Those nodes are now stable.

A question to the 'cp gurus' out there: is my guess correct about
the bad blocks list?
