Increasing size of root partition

Linux and Unix-Like Red Hat

Dear All ,

We need to increase the size of the root partition in a RHEL server.

The model is Product Name: SUN FIRE X4170 SERVER.

  
 Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/VolGroup00-LogVol00
                      119G   47G   67G  41% /
/dev/sda1              99M   15M   80M  16% /boot
tmpfs                  12G   12K   12G   1% /dev/shm
none                   12G  104K   12G   1% /var/lib/xenstored

Pl let me know as it is a physical server , do we need to add more disks for increasing size or any other ways.

Thanks and rgds
Rj

I don't see the immediate need to modify anything as there's almost 60% free on the disk/volume/partition that is mounted on root.
For further advice more info i needed like the partitioning scheme of the disk, and other disks available.

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.

pvs
vgs
lsblk
cat /proc/partitions

Some of these commands must be issue with root privileges.

suppose if ever need to increase
add additional space in root volume group
and increase the respective LV size
