===============================================================
|
|
Increase Controller Filesystem Storage Allotments Using the CLI
|
|
===============================================================
|
|
|
|
You can use the |CLI| to list or increase the allotments for controller-based
|
|
storage at any time after installation.
|
|
|
|
.. rubric:: |context|
|
|
|
|
For more information about increasing filesystem allotments, or to use the
|
|
Horizon Web interface, see :ref:`Increase Controller Filesystem Storage
|
|
Allotments Using Horizon
|
|
<increase-controller-filesystem-storage-allotments-using-horizon>`.
|
|
|
|
.. caution::
|
|
Decreasing the filesystem size is not supported, and can result in
|
|
synchronization failures requiring system re-installation. Do not
|
|
attempt to decrease the size of the filesystem.
|
|
|
|
.. rubric:: |prereq|
|
|
|
|
Before proceeding, review the prerequisites given for :ref:`Increase
|
|
Controller Filesystem Storage Allotments Using Horizon

The values shown by :command:`system controllerfs-list` are not

agree with the output of the Linux :command:`df` command. Also,

.. note::
|
|
|
|
When you use the :command:`system host-fs-modify` to increase
|
|
the filesystem size, you may not have enough space in the |LVG| due to
|
|
additional services running on the controller host. To increase the size
|
|
from the default size of 30G to 60G for example, the docker filesystem,
|
|
see below:
|
|
|
|
.. code-block:: bash
|
|
|
|
# check existing size of docker fs
|
|
system host-fs-list controller-0
|
|
# check available space (Avail Size (GiB)) in cgts-vg LVG where docker fs is located
|
|
system host-lvg-list controller-0
|
|
# if existing docker fs size + cgts-vg available space is less than
|
|
# 80G, you will need to add a new disk partition to cgts-vg.
|
|
# There must be at least 20GB of available space after the docker
|
|
# filesystem is increased.
|
|
|
|
# Assuming you have unused space on ROOT DISK, add partition to ROOT DISK.
|
|
# ( if not use another unused disk )
|
|
|
|
# Get device path of ROOT DISK
|
|
system host-show controller-0 --nowrap | fgrep rootfs
|
|
|
|
# Get UUID of ROOT DISK by listing disks
|
|
system host-disk-list controller-0
|
|
|
|
# Create new PARTITION on ROOT DISK, and take note of new partition's 'uuid' in response
|
|
# Use a partition size such that you'll be able to increase docker fs size from 30G to 60G
|
|
PARTITION_SIZE=30
|
|
system hostdisk-partition-add -t lvm_phys_vol controller-0 <root-disk-uuid> ${PARTITION_SIZE}
|
|
|
|
# Add new partition to 'cgts-vg' local volume group
|
|
system host-pv-add controller-0 cgts-vg <NEW_PARTITION_UUID>
|
|
sleep 2 # wait for partition to be added
|
|
|
|
# Increase docker filesystem to 60G
|
|
system host-fs-modify controller-0 docker=60
|
|
|
|
#. Modify, for example, the extensions controller filesystem on the
|
|
controller(s).
|
|
|
|
.. code-block:: none
|
|
|
|
