Client Mount Options

[behlendorf]

There are a number of useful filesystem mount options for xfs, gfs2, and lustre which we may need to be able to specify as part of a workflow. There is currently support to provide custom options when the filesystems are created. This would potentially be a nice place to specify what options are used when they are mounted.

Brian, mount options can be specified in the StorageProfile.

Look here for "mountRabbit"; and "mountTarget" for the lustreFS OST,MGT,MDT mounts; and there's "mountCompute" for the compute nodes:

We don't allow these to be specified in the Workflow, but we do allow the Workflow to specify the StorageProfile. Then the admin should create the StorageProfile.

Great, thanks for pointing that out. Then do I understand correctly that MountRabbit is used when mounting the filesystem on a compute or rabbit node? Or is there also a MountCompute? Can these be used with all the filesystem types?

[roehrich-hpe]

MountRabbit and MountCompute work with all filesystem types. The former indicates mount options to be used on a Rabbit, and the latter is the mount options to be used on a compute node.

Use mountTarget to specify mount options for OST,MGT,MDT devices.
