What's my SMB status on the cluster? version?

Often we have a mixed environment of client machines accessing the SMB stack on an Isilon cluster questions arise around which versions of SMB are being used by the clients and how many are connected.

The SMB v2 support got added in around version OneFS 6.5.5.4 and higher, previously it was only SMB v1 supported.  Today SMB 3 isn't supported with the cluster.

On OneFS version 6.5. You can login to the command line and run.

'isi smb config global list'. If it states that 'support-smb2=true, then you are running SMB v2, the same goes for SMB v1.

On OneFS version 7 you can check what's enabled for usage on your cluster with the following cli command.  It changed slightly in 7.0

'isi smb settings global view'

Once you've confirmed that your cluster is in fact running the version that you wish you can check your clients and count the numbers with the following cli commands.  (sorry I find CLI faster )

isi statistics protocol  --protocols=smb1,smb2 --top

isi statistics client  --protocols=smb1,smb2 --top

(give me a running total of my client connections - think of the regular linux top command)

isi statistics client  --protocols=smb1,smb2  | grep smb1 | wc -l

(how many smb1 clients)

isi statistics client  --protocols=smb1,smb2  | grep smb2| wc -l

(how many smb2 clients)

If you have newer client machines such as Windows 8 and Windows 2012 server check the Isilon 6.5.5.x release notes for enhanced support/compatibility.  You may want to consider installing a code level of 6.5.5.22 as of this posting. (again verify with your support team before you change anything)

Hope this helps with checking out what's happening in SMB land of your cluster.
