Or can only one logical volume be mounted to a mount point? Aad, you can only mount one device with a filesystem on the same mountpoint. What needs doing in order to grow your logical volume containing the usr filesystem, is to *add* the second drive to the existing volume group on the first one and grow usr afterwards (LV and FS). Carry out the follwoing steps (or use system-config-lvm): lvremove VolGroup01/LogVol01 vgremove VolGroup01 vgextend VolGroup00 /dev/sdb # or whatever the drive is # replace 5G with the capacity you want to add lvextend -L+5G VolGroup00/LogVol01 How to grow the FS depends on the type; for ext2/3 you'ld run: ext2online /dev/VolGroup00/LogVol00 > > Aad > > _______________________________________________ > 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/ -- Regards, Heinz -- The LVM Guy -- *** Software bugs are stupid.
