i have looked around the net and not found much info about this... i have a centos 5 system with a 32m pe size vg and have attached some storage with an lvm1 4m pe size vg. i converted the old vg to lvm2 without problem, but i would like to merge the volumes and pvmove data onto the newer 32m pe pvs. but you can't merge things with different pe size, so i've been trying to get the 4m pe vg changed to 32m pe. after much monkeying around i was able to get all the pvs and lvs to have le counts that were the right size to be convertible to 32m pe. but it looks like each segment must be sized appropriately and i can't find a way to merge segments together so that things are sized correctly. the most recent error is: # vgchange -s 32m lv New size 209051648 for disk0 segment length not an exact number of new extents. would i be better off converting the 32m pe vg to 4m pe? this is all with lvm2 now, and what i read says that the 64k segment limit doesn't exist anymore, so 4m pe isn't a limiting factor for lv sizing. or is there a way i can combine segments so they are sized appropriately? i've got enough space that i should be able to pvmove stuff around to coalesce segments, but it isn't clear if there is a tool to do that. if all else fails, i guess i'll just have to do a filesystem level copy onto the 32m pe vg. or is there some other magic i'm missing? _______________________________________________ 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/
