extending a partition on Linux / VMware /SAN disk without gparted

First of all extend the hard disk size, either using vmware console, san console or vmdisk-vmanager command.

In my example i extend sda from 10 to 12 GB.

In my current linux:
/dev/sda1,2,3 --> primary partition

/dev/sda4 --> extended partition
/dev/sda5 --> inside sda4, it is also the /home partition

After extend, see the result using fdisk -l,
Notice if the HD size now is 12 GB.
However the partition sector/unit is still remain the same as before.


Since the last sector is /dev/sda4, so now we extend it sda4 first, then we could extend the sda5.

using parted :
# select /dev/sda
# unit mb
# print
# resize 4 xxxxx yyyyy

xxxx is the beginning of the sector
yyyy is the end of sector

Notice that now the /dev/sda4 has some more spaces.

after that we need to resize the /dev/sda5

Follow this link to extend the size:

unfortunately resize ext3 can be failed with error like "file system has an incompatibility feature" which is caused by the ext3 has been customized by redhat.

The quick way is just by using fdisk, remove the sda5 partition, and create again using the total sector of /dev/sda4.

Now u have /dev/sda5 extended size.


The longest way is by modifying all the custom attribute redhat:
