This doesn't directly address your issue, but I'd point out that if /boot were itself an lv instead of a normal partition, resizing it would be easy ;) Personally I just leave /boot on the root lv. > Looks like all extents are already allocated (that's the 'a', right?). > But it claims that 10G are free!

Is there any way to accomplish this? pvmove normally is used to move segments off the pv to other pvs in order to free up that pv for removal. So it is failing since it can not find space on other disks, since you limited its search to specific extents on the same disk. You need to add --alloc anywhere to stop it from excluding the current disk from its search. The need for this is kind of silly given that you explicitly tell it where to move to, it should probably be assumed, but isn't. _______________________________________________ linux-lvm mailing list linux-lvm@redhat.com https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
