Dear If u have two harddisk or partition then u have to create physical volume then u can add multiple PV in to single VG. so there is no way to combine two hard drive or two parttion into single PV , as i know . thanks Paul <unix at bikesn4x4s.com> wrote: What's the easiest way to transition to a larger HD when using LVM2? I'm running Centos 4.4. I'm going from a 20gb HD to a 40gb HD. I've already DD'd it to the 40gb HD. So now I have 20gb of unused space. Ideally, I'd like to make it one big physical space for the logical space instead of making another physical partition to expand the logical. Here is what I have now with the system on hda, and with another HD of hdb for moving data if i need to: # fdisk -l Disk /dev/hda: 41.1 GB, 41174138880 bytes 255 heads, 63 sectors/track, 5005 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/hda1 * 1 13 104391 83 Linux /dev/hda2 14 2501 19984860 8e Linux LVM Disk /dev/hdb: 15.3 GB, 15361597440 bytes 255 heads, 63 sectors/track, 1867 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/hdb1 1 1867 14996646 83 Linux _______________________________________________ CentOS mailing list CentOS at centos.org http://lists.centos.org/mailman/listinfo/centos Abhishek Kr.
