Fix a bug cephfs subvolume size calculation
The charm is documented to take the 'size' in gigabytes.
But when passing it down to 'ceph fs subvolume', it's incorrectly
calculating the bytes.

ceph-nfs

Description

CephNFS is a charm designed to enable management of NFS shares backed by CephFS. It supports Ceph Pacific and above.

Usage

CephNFS provides an additional service when deployed with Ceph and CephFS. It should be related to CephMon:

juju add-relation ceph-nfs:ceph-client ceph-mon:client

Once all relations have settled, it is possible to create a new export:

juju run-action --wait ceph-nfs/0 create-share name=test-share size=10 allowed-ips=10.0.0.0/24

The above command has creates an NFS share that is 10GB in size, and is accessible from any machine in the 10.0.0.0-10.0.0.255 network space. To grant access to a new network address, the grant-access action should be used:

juju run-action --wait ceph-nfs/0 grant-access name=test-share allowed-ips=192.168.0.10

This command has granted access to the named share to a specific address: 192.168.0.1.

It is possible to delete the created share with:

juju run-action --wait ceph-nfs/0 delete-share name=test-share

High Availability

To gain high availability for NFS shares, it is necessary to scale ceph-nfs and relate it to a loadbalancer charm:

juju add-unit ceph-nfs -n 2
juju config vip=10.5.0.100
juju deploy hacluster
juju add-relation ceph-nfs hacluster

Once everything settles, your shares will be accessible over the loadbalancer's vip (10.5.0.100 in this example), and connections will load-balance across backends.

Relations

Ceph-NFS consumes the ceph-client relation from the ceph-mon charm.

Bugs

Please report bugs on Launchpad.

For general charm questions refer to the OpenStack Charm Guide.

Note that starting with the squid track of the ceph-nfs charm, deployment of Ceph Pacific and older clusters is not supported anymore.
