Thanks and rgds

Your root partition leaves in a LVM volume named LogVol00, which is part of a volume group named VolGroup00. Sometimes there's more space not allocated in the group volume. If that's the case, you might not need to add more disk space, but rather extend the lv.

In any case, to give you a more adequate response extra information is necessary.

If you do not mind, please, report back the output of the following commands.
Code:
pvs
vgs
lsblk
cat /proc/partitions

Some of these commands must be issue with root privileges.

VGDISPLAY(8)                                                  System Manager's Manual                                                 VGDISPLAY(8)

NAME

       vgdisplay - display attributes of volume groups

SYNOPSIS

       vgdisplay  [-A|--activevolumegroups]  [-c|--colon|-s|--short|-v|--verbose]  [-d|--debug]  [-h|--help] [--ignorelockingfailure] [--nosuffix]
       [-P|--partial] [--unitshHbBsSkKmMgGtTpPeE] [--version] [VolumeGroupName[VolumeGroupName...]]

       vgdisplay      --columns      |      -C      [--aligned][-d|--debug][-h|-?|--help]       [--ignorelockingfailure][--noheadings][--nosuffix]
       [-o|--options[+]Field[,Field]]  [-O|--sort[+|-]Key1[,[+|-]Key2[,...]]]   [-P|--partial] [--separatorSeparator] [--unbuffered] [--unitshHbB-
       sSkKmMgGtTpPeE] [-v|--verbose] [--version] [VolumeGroupName[VolumeGroupName...]]

DESCRIPTION

       vgdisplay allows you to see the attributes of VolumeGroupName (or all volume groups if none is given) with it's physical and  logical  vol-
       umes and their sizes etc.

       vgs (8) is an alternative that provides the same information in the style of ps (1).

OPTIONS

       See lvm for common options and vgs for options given with --columns.

       -A, --activevolumegroups
              Only select the active volume groups.

       -c, --colon
              Generate colon separated output for easier parsing in scripts or programs.  N.B. vgs (8) provides considerably more control over the
              output.

              The values are:

              1  volume group name
              2  volume group access
              3  volume group status
              4  internal volume group number
              5  maximum number of logical volumes
              6  current number of logical volumes
              7  open count of all logical volumes in this volume group
              8  maximum logical volume size
              9  maximum number of physical volumes
              10 current number of physical volumes
              11 actual number of physical volumes
              12 size of volume group in kilobytes
              13 physical extent size
              14 total number of physical extents for this volume group
              15 allocated number of physical extents for this volume group
              16 free number of physical extents for this volume group
              17 uuid of volume group

       -s, --short
              Give a short listing showing the existence of volume groups.

       -v, --verbose
              Display verbose information containing long listings of physical and logical volumes.  If given twice, also display verbose  runtime
              information of vgdisplay's activities.

       --version
              Display version and exit successfully.

       --columns|-C
              Display output in columns, the equivalent of vgs.  Options listed are the same as options given in vgs (8).
