yes... Thats striping why use a stripe size equal to that of a logical
extent I would have expected you to want them much smaller than that!
the default for striping on lvm is 8k. I my LE size is 16 meg,
16 meg strips would be a bit pointless in my book. Anyway using -I you can
set it to what you want.
lvcreate -i <num> -I <K> .....
from the lvcreate man page
-i, --stripes Stripes
Gives the number of stripes. This is equal to the
number of physical volumes to scatter the logical
-I, --stripesize StripeSize
Gives the number of kilobytes for the granularity
of the stripes.
StripeSize must be 2^n (n = 2 to 9)
