Warning

Setting up SFS in a tenancy can be done only by users with ewcloud-tenant-admin role!


Ticket

SFS should be available for tenants created after 28/10/2022, if the tenant is older and you wish to use SFS, please open us a ticket here.

1. Create Server Openstack SFS

1.1 From Morpheus go to Infrastructure → Storage, select the Servers tab and click +ADD

...

Once saved this will create the storage server.

2. Create a File share

Now that you have a storage server for SFS, you can create the File shares,

...

This will create the Shared Filesystem in the storage backend. Wait until you have the "Share Path:" defined in Morpheus. This will take some time.

3. Network configuration required for the VMs that need to access the SFS

Now that you have created the SFS, you can use it in a VM.

...

Once provisioned is finished, ssh into your machine and verify if the SFS network is up:

Code Block
ip addr show


Ubuntu 22 known issue due to race condition in cloud-init - Nov 2023

When running the ip addr show  command, you will notice that one network is not up by default. This is due to a known issue in Ubuntu 22 cloud-init that will be fixed in future updates.

...

  1. Create a file and save it under this path /etc/cloud/cloud.cfg.d/99-disable-network-config.cfg with content:

    network: {config: disabled} 


  2. Modify and save the cloud file at this path /etc/netplan/50-cloud-init.yaml adding the following lines in the list of ethernets:

    Code Block
            ens4:
            dhcp4: true
            match:
                macaddress: COPY HERE THE ONE IDENTIFED FROM the command ip addr show for ens4 (e.g. fa:16:3e:14:d6:4c)
            set-name: ens4
            optional: true

    So you will have something like this at the end:

    Code Block
    # This file is generated from information provided by the datasource.  Changes
# to it will not persist across an instance reboot.  To disable cloud-init's
# network configuration capabilities, write a file
# /etc/cloud/cloud.cfg.d/99-disable-network-config.cfg with the following:
# network: {config: disabled}
network:
    ethernets:
        ens3:
            dhcp4: true
            match:
                macaddress: fa:16:3e:c3:6d:1f
            set-name: ens3
        ens4:
            dhcp4: true
            match:
                macaddress: fa:16:3e:14:d6:4c
            set-name: ens4
            optional: true

    version: 2


  3. Run the following command:

    Code Block
    netplan apply


  4. Finally verify the network is up, running ip addr show  again



4. Adding permissions to use the Shared Filesystem

Once the Shared Filesystem is created, you need to add access rules to allow read-only or read/write operations to one machine or multiple machines.

...

You will be able to see your private network and sfs network IPs:


5. Mount file share to VM

Now that everything is configured and permissions have been given for access, you can login into your machine and mount the shared filesystem in a VM using the following commands:

...
