CIFS session force close before ONTAP upgrade

sfrmast

How can we close cifs share connections forcefully. I Tried all but session is keep coming.

Is it mandatory to close all session.

Kindly advice

 

vserver cifs session file close -node * -session-id <sessionid

cifs session close -node * -vserver vServer-01

cifs session close -node * -vserver vserver_name -connection-id 22XXXXX

As you are doing a ONTAP upgrade and CIFS* being connection oriented (*=Non-Continuously available) will drop-out anyway even if it is NDU, so I am sure the end-users are already notified.

 

There are two types of CIFS shares:
1) Continuously available CIFS shares : Which are accessed by Hyper-V or Microsoft SQL Server clients using the SMB 3.0 protocol, do not need to be terminated before upgrading

:: > vserver cifs session show -continuously-available Yes

 

2) Non Continuously available : Before upgrading the ONTAP software, you should identify and gracefully terminate any CIFS sessions that are "not continuously" available.
:: > vserver cifs session show -continuously-available !Yes

 

If the sessions are not CLOSING, as you mentioned, just stop the CIFS Server, provided the CIFS are No-continuously-available shares.


Just follow this steps:
1. Stop the CIFS server
::> vserver cifs stop -vserver vserver_name

 

2. Start the CIFS server
::> vserver cifs start -vserver vserver_name

 

3. Check the sessions:
:: > vserver cifs session show

 

If none. Proceed with the Upgrade.

What will happen if see session and we proceed the upgrade , what would be the impact any idea. is it recommended 

parisi

Same impact as force closing the sessions. Basically, you're performing the step that the upgrade would do. When you giveback the node, you can use -override-vetoes to ignore open CIFS sessions,

Do not worry. You will be fine. If your CIFS environment is super busy and you do come across any issue with locks during upgrade , just follow this kb.
