Hello all!
With the installation of Openshift Origin 3.9 cluster I've followed the
storage requirements described here:
https://docs.openshift.org/latest/install_config/install/prerequisites.html#hardware
With the framework up and some test deployments run, I'm trying to
centralize configuration for a later installation. I'm using centOS 7 as
the base operating system.
I wanted to ask about the storage requirements regarding masters and
nodes. On my current framework I have 2 masters that are also
infrastructure nodes and 2 compute nodes.
During install I could see there's heavy use of the /tmp so I understand
why the 1GB requirement.
But I'm looking at /usr/local/bin and especially /var and the space used
by my current installation is far less than what is stated as a minimum.
/usr/local/bin is completely empty on all hosts and for /var it's at
most 3.6GB used on one of the masters (with 42GB allocated to meet the
40GB free requirement/check); on the nodes the /var partition is below
500MB used. The space is mostly used by system logging and Openshift's
audit logging(on the masters).
In what context do these partitions fill/are used up to their stated
requirements?
Thank you,
Dan Pungă
