Current lvm version anyway. I wanted mine to be more flexible, so I first made a software raid set then made the pv on top of the raid. That was in Jan this year. Last week I doubled the size by adding another software raid set. I expanded two of the ext3 formatted lvs in the process. Perhaps not the fastest system in terms of throughput, but quite convenient to resize. -tkb _______________________________________________ linux-lvm mailing list linux-lvm@sistina.com http://lists.sistina.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
