lvcreate fails when using striping
Last modified: 2007-11-30 17:10:53 EST
Description of problem:
lvcreate fails when using striping but completes if this is omitted.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Initialise multiple disks with pvcreate
2. Create new volume group with vgcreate
3. Run vgdisplay then try to create a striped volume covering the
entire extent of the group using the free size reported.
Creation fails citing a requirement for less allocatable extents than
are listed as free by vgdisplay
Creation should succeed.

which is not divisible by 4, so your disks can't be identical in size.
You can only have 4-way striping until you've filled your smallest disk.
