How to add space in various Unix OS flavors

How to add space in various Unix OS flavors.

1. Increase space in Linux

a) Identify the LV/mount point on which space needs to be increased.

b) Note the current LV/mount point size using

“df –h </mount point>”

c) Suppose you want to increase space by 1 GB , then

lvextend -L +1G </dev/{vgname}/{lvname}>

eg. lvextend -L +1G /dev/vg01/kirdata1

d) After increasing LV size , extend the Filesystem using

eg. resize2fs -p /dev/mapper/vg01-kirdata1

e) Verify the new mount point size using

“df –h </mount point>”

2. Increase space in AIX

a) Identify the LV/mount point on which space needs to be increased.

b) Note the current LV/mount point size using

“df –g </mount point>”

c) Suppose you want to increase space by 1 GB , then

chfs –a size=+1G </mount point>

d) Verify the new mount point size using

“df –g </mount point>”

3. Increase space in HPUX

a) Identify the LV/mount point on which space needs to be increased.

b) Check if Online JFS is installed

swlist -l product | grep -i jfs

c) Note the current LV/mount point size using

“bdf </mount point>”

d) Obtain the current size of the Logical Volume (Mbytes)

lvdisplay  </dev/volumegroup/logicalvolume>

e) Adjust the size of the Logical Volume.

lvextend -L <new_size_in_mbytes>

{ New size ( in MB )=  current size ( in MB )+ size to increase ( in MB ) ( eg 1GB = 1024 MB) }

f) Adjust the size of the Filesystem

fsadm -b <new_size>M </mountpoint>

g) Verify new size by using

“bdf  </mount point>”
