Full Discussion: Allot free space from one partition to other
Operating Systems Linux Red Hat Allot free space from one partition to other Post 302934927 by omniok on Thursday 12th of February 2015 01:46:07 AM

Allot free space from one partition to other
I have a RHEL 5.3 machine with the following partitions and free space:

Free space on the partitions
Code:
/     : 74GB
/boot : 81MB
/var  : 73GB
/home : 37GB
/icat : 758MB
/opt  : 1.5GB

Now is it possible to allot a free space of some other partitions to /opt? I want around 100 GB more space on /opt. Thus, if it is possible I could move 50GB from /var and /20 GB from /home to /opt. This can make at least 70 GB space available. The partition table type is msdos. The output of "fdisk" command is attached herewith.

What are other possible ways to increase space on /opt?
Thanks in advance !!!

SYSTEMD-GPT-AUTO-GENERATOR(8)				    systemd-gpt-auto-generator				     SYSTEMD-GPT-AUTO-GENERATOR(8)

NAME

       systemd-gpt-auto-generator - Generator for automatically discovering and mounting /home as well as discovering and enabling swap
       partitions, based on GPT partition type GUIDs.

SYNOPSIS

       /usr/lib/systemd/system-generators/systemd-gpt-auto-generator

DESCRIPTION

       systemd-gpt-auto-generator is a generator that automatically discovers /home and swap partitions and creates mount and swap units for them,
       based on the the partition type GUIDs of GUID partition tables (GPT). Note that this generator will execute no operation on non-GPT
       systems, on systems where the units are explicitly configured (for example, listed in fstab(5)) or where the mount point is non-empty.

       This generator will only look for partitions on the same physical disk the root file system is stored on. This generator has no effect on
       systems where the root file system is distributed on multiple disks, for example via btrfs RAID.

       This generator is useful for centralizing file system configuration in the partition table and making manual configuration in /etc/fstab or
       suchlike unnecessary.

       This generator looks for swap partitions using GPT type 0657fd6d-a4ab-43c4-84e50933c84b4f4f. It looks for /home partitions using GPT type
       933ac7e1-2eb4-4f13-b8440e14e2aef915.

       systemd-gpt-auto-generator implements the generator specification[1].
