Thanks for the reply, Bryn.
OK, I'm confused.
The LVM Howto says "In LVM 2, striped LVs can be extended by concatenating
another set of devices onto the end of the first set. So you can get into a
situation where your LV is a 2 stripe set concatenated with a linear set
concatenated with a 4 stripe set. Are you confused yet?"
I interpret the above to mean that I can concatenate the single drive after
the existing stripped array. Is that an incorrect interpretation?
Being as this LV stores backups, I don't really care too much that it is
stripped--my goal is to have lots of disk space. Is my only option trashing
the existing LV and making it contiguous (non-stripped)? Thanks!
Paul
