Unable to readd vfiler into domain with same name.

[SATYAIRRINKI1]

hostname of Vfiler has been removed from windows AD and readded.

Trying to readd Vfiler into domain with same hostname for CIFS access.

>vfiler run <filer name > cifs terminate --throws error

CIFS: CIFS did not shut down: CIFS terminate aborted because client sessions did not disconnect properly.

>vfiler run <filer name > cifs sessions ---shows nothing.

Request you to assist on the same ..

You must first terminate cifs services and then try to delete AD account of filer.

Now you can try to failover {using halt -f or -d command to clear it}

And then rejoin to domain.

Not able to terminate session please find log for the same ..

There is no fail over configured for it ..halt -d/-f whill it shutdown filer or vfiler ?

[martin_fisher]

Hi - have you tried a CIFS restart on the vFiler to restart and the service or a CIFS setup. You can delete the AD Account for the vFiler, without shutting down CIFS.

If CIFS fails to terminate, then you may need to restart the vFiler first, then try again.

[sharmadevender]

yes halt -d will shutdown the filer creating dump. What's the Data ontap version, because we can see bug related to cifs termination in few Ontap and halt -d is only solution.

[SATYAIRRINKI1]

Ontap 7.3.1.1,We cant shutdown the Filer which will effect other cifs shares hosted on Filer.Can't we forcely terminate cifs sessions for vfiler and readd to domain.

If cifs service is up then cifs restart will wont work .Instead try connecting vfiler using windows host (with admin login)  close all three opened files which are in write + read mode Then try cifs terminate .

[martin_fisher]

Connect to the vFiler using the Windows MMC and manage the host. You should the be able to see any open files of folders. If not restart the vFiler (not the host filer).

[ASHWANI8HIGHS]

I think we missed something    if the vfiler has been removed from AD we cannot connect it to using Windows MMC . I think you have to  re - run the Cifs setup  add the vfiler to domain ,close your open files connecting  vfiler from Windows MMC ,cifs terminate ,exclude the vfiler from domain  .

[martin_fisher]

But if you cant terminate CIFS to start with how are you going to re-run the setup?

vFiler needs a restart.

[ASHWANI8HIGHS]

I agree with Martin  .. you need to restart the vfiler

[SATYAIRRINKI1]

Thanks for your support and quick reverts.

The only option worked out for me is to reboot the filer and re-add vfiler to domain using 'vfiler run <filername> cifs setup'.

I am thinking of other option, other than rebooting the filer?...may be not available ..

[SATYAIRRINKI1]

Is this command useful -"lock break -p cifs"

[sharmadevender]

In your case, when you run CIFS session, no active sessions were there. So lock command will add no help.
