[lustre-discuss] lctl dl output fields

I don't think there is anything that explicitly documents the fields. I don't have a system handy, but from memory the fields are:
- device number
- state of the connection
- device type
- device name
- device UUID
- refcount

That said, you are probably better off to use "lfs df" or "lfs osts" and "lfs mdts" to list the devices connected to a client.

Cheers, Andreas

Is there any documentation on what the fields in the ‘lctl dl’ output mean? I have seen examples in the admin manual of its output but would like to understand what is/could be in the various fields and what that indicates.

(As a background, I am trying to find out what ‘exists’ in a Lustre cluster and their relationships and this seems like a good place to start. E.g. find filesystems, OSSs, their specific OSTs etc. in a cluster from a single location)
