What you want is "reshape" not extend. This was committed as RAID
feature to 2.02.169, but it is still somewhat experimental. You would
need to convert stripe LV to RAID0 (aka takeover) and then reshape.
thanks, I see it more clearly now.
Is it possible to get rid of that second segment now? Have the LV prior
to extension?
Either lvresize to previous size or vgcfgrestore would work UNLESS you
resized the filesystem as well. vgcfgrestore has more limitations - no
other metadata altering operations were performed on VG since the change.
