第4章 Verify native CephFS back end deployment

Deploying native CephFS as a back end of the Shared File Systems service (manila) adds the following new elements to the overcloud environment:

  • Storage provider network
  • Ceph MDS service on the Controller nodes

For more information about using the Shared File Systems service with native CephFS, see Shared File Systems service in the Storage Guide.

The cloud administrator must verify the stability of the native CephFS environment before making it available to service users.

Prerequisites

4.1. Verifying creation of isolated storage network

The network_data.yaml file used to deploy native CephFS as a Shared File Systems service back end creates the storage VLAN. Use this procedure to confirm you successfully created the storage VLAN.

Procedure

  1. Log in to one of the Controller nodes in the overcloud.
  2. Check the connected networks and verify the existence of the VLAN as set in the network_data.yaml file:

    $ ip a
    8: vlan30: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN group default qlen 1000
        link/ether 52:9c:82:7a:d4:75 brd ff:ff:ff:ff:ff:ff
        inet 172.17.3.144/24 brd 172.17.3.255 scope global vlan30
           valid_lft forever preferred_lft forever
        inet6 fe80::509c:82ff:fe7a:d475/64 scope link
           valid_lft forever preferred_lft forever
