So I can just install LVM2 and continue as usual, and switch back if I get into trouble? And, what if I get into trouble? I can not backup all data. There is not enough space for that. >> Also, is it possible to convert (with and LVM version) a spanded >> volume to a striped volume? > Not until we get the new pvmove infrastructure. So, when newer pvmove tools develops it would be possible to convert a spanned volume to a sriped (RAID0 or 5?) volume without loosing data? Right now I have about 10 disks that are spanned with LVM1. I would really want to be able to convert this to a striped volume with redundancy, like RAID 5. > If you do try LVM2 please give us feedback on how easy the transition > was and what extra documentation you would like to see.

I will, when I see that the above could work. =) > - Joe //Anders _______________________________________________ linux-lvm mailing list linux-lvm@sistina.com http://lists.sistina.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://www.sistina.com/lvm/Pages/howto.html
