Description Simon Andrews 2004-11-09 10:23:42 EST
Description of problem:

lvcreate fails when using striping but completes if this is omitted.

Version-Release number of selected component (if applicable):


How reproducible:


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.  
Actual results:

Creation fails citing a requirement for less allocatable extents than
are listed as free by vgdisplay

Expected results:

Creation should succeed.

 Total PE              122506

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.
