increasing root / partition

Dear all,

I have a root partition which is 20 G in size. I have var and /tmp as seperate file systems. But this 20 G of root is not sufficeint.

I want to increase the size of the / partition.

Is there any way to increase with out down time.

my df -k output is

Code:

systemd-veritysetup-generator

SYSTEMD-VERITYSETUP-GENERATOR(8)                           systemd-veritysetup-generator                          SYSTEMD-VERITYSETUP-GENERATOR(8)

NAME

       systemd-veritysetup-generator - Unit generator for integrity protected block devices

SYNOPSIS

       /lib/systemd/system-generators/systemd-veritysetup-generator

DESCRIPTION

       systemd-veritysetup-generator is a generator that translates kernel command line options configuring integrity protected block devices
       (verity) into native systemd units early at boot and when configuration of the system manager is reloaded. This will create systemd-
       veritysetup@.service(8) units as necessary.

       Currently, only a single verity device may be se up with this generator, backing the root file system of the OS.

       systemd-veritysetup-generator implements systemd.generator(7).

KERNEL COMMAND LINE

       systemd-veritysetup-generator understands the following kernel command line parameters:

       systemd.verity=, rd.systemd.verity=
           Takes a boolean argument. Defaults to "yes". If "no", disables the generator entirely.  rd.systemd.verity= is honored only by the
           initial RAM disk (initrd) while systemd.verity= is honored by both the host system and the initrd.

       roothash=
           Takes a root hash value for the root file system. Expects a hash value formatted in hexadecimal characters, of the appropriate length
           (i.e. most likely 256 bit/64 characters, or longer). If not specified via systemd.verity_root_data= and systemd.verity_root_hash=, the
           hash and data devices to use are automatically derived from the specified hash value. Specifically, the data partition device is looked
           for under a GPT partition UUID derived from the first 128bit of the root hash, the hash partition device is looked for under a GPT
           partition UUID derived from the last 128bit of the root hash. Hence it is usually sufficient to specify the root hash to boot from an
           integrity protected root file system, as device paths are automatically determined from it -- as long as the partition table is
           properly set up.

       systemd.verity_root_data=, systemd.verity_root_hash=
           These two settings take block device paths as arguments, and may be use to explicitly configure the data partition and hash partition
           to use for setting up the integrity protection for the root file system. If not specified, these paths are automatically derived from
           the roothash= argument (see above).
