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

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.

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

NAME
partition - make a partition table SYNOPSIS
partition [-mf] device [type:]size[+*] ... DESCRIPTION
Partition makes a partition table on device using the types and sizes given. It may be used in combination with repartition(8) for auto- matic installation of Minix. You may give up to four type:size[+*] specifications for the partitions. You may also specify holes before, between, and after the parti- tions. A hole differs from a partition specification by not having a type. The first hole is by default 1 sector to make space for the primary bootstrap and the partition table. The other holes are 0. The type field is the type of the partitition in hexadecimal. The size field is the partition's size in sectors. The + or * may option- ally be added to indicate that the partition must be expanded to contain any leftover space on the device or to mark the partition active. Partitions are padded out to cylinder boundaries, except for the first one, it starts on track 1. Some operating systems care about this. Minix and MS-DOS do not. OPTIONS
-m Minix only, no need to pad partitions. This is the default for subpartition tables. -f Force making a partition table even if the device is too small. EXAMPLE
partition /dev/hd0 01:16384 81:40000 81:2880* 06:20000+ Partitions disk 0 into an 8 Mb DOS partition, 20 Mb Minix /usr, 1.44 Mb Minix / (active), and a DOS partition of at least 10 Mb at the end of the disk. (06:0+ would have been ok too, it's just a sanity check.) SEE ALSO
