Thanks for your help everyone. My server service contact told me he thought there were 50GB that were unallocated yet that I could use, but I still can't find them. When I run fdisk -l, this is what I get: Disk /dev/sda: 21.4 GB, 21474836480 bytes 255 heads, 63 sectors/track, 2610 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sda1 * 1 13 104391 83 Linux /dev/sda2 14 2610 20860402+ 8e Linux LVM Disk /dev/sdb: 53.6 GB, 53687091200 bytes 255 heads, 63 sectors/track, 6527 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk /dev/sdb doesn't contain a valid partition table That should show me all the disks I have at my disposal right? And pvdisplay gives me: --- Physical volume --- PV Name /dev/sda2 VG Name vg PV Size 19.89 GB / not usable 19.49 MB Allocatable yes (but full) PE Size (KByte) 32768 Total PE 636 Free PE 0 Allocated PE 636 PV UUID Tc3LZt-mYmJ-V124-Qz5c-UJed-bj5f-6Y9xk7 --- Physical volume --- PV Name /dev/sdb VG Name vg PV Size 50.00 GB / not usable 32.00 MB Allocatable yes (but full) PE Size (KByte) 32768 Total PE 1599 Free PE 0 Allocated PE 1599 PV UUID JBNdp2-rZmF-jfEv-qFVa-eOPK-EU7A-Tz9s1L Which, to me, suggests all the disk space is allocated. But, I have another question. I sent the below output previously for df -h and lvmdiskscan. I'm curious if the /dev/mapper/vg-... references (e.g. vg-usr, vg-home, vg-var etc.) in df -h are actually different than the /dev/vg/... references to the same names (e.g. usr, home, var, etc.) in lvmdiskscan or if they refer to the same thing. It is a little confusing to me. Again, thanks for the help.
