[linux-lvm] Stripe size of 2K allowed?

[linux-lvm] Stripe size of 2K allowed?

[Jos Visser]

Hi,

I was trying to create a striped lvol with a stripe size of 2K. This
failed due to an illegal parameter:

# lvcreate -i 2 -I 2 -L 100 vg01
lvcreate -- invalid stripe size 2

It seems that stripe sizes of 1K and 2K are not allowed, although the
lvcreate manual page says that the stripe size is 2^n with 0<=n<=7.

Duh?

This has been changed so the minimum size is the page size of your
system.  I'll update the man page.

An error in the documentation.
The minimum stripe size is 4k.

Going to correct it...
