Enable SMB continuous availability on existing share
Hello
Is it possible to enable SMB continuous availability on an existing share on an Isilon.
The share has folders and data in it.
The GUI option is grayed out , as it was not done when the share was created
Thanks

No, the share must be re-created. From my understanding this is how it works on a Windows server as well. I haven't tried that, but I heard it from a usually reliable source.

furthermore if you delete the share you dont delete the data in the filesystem. So a recreation shouldn't be a problem.
this can be done in a single command line..
isi smb share delete ... ; isi smb share create ...

There is a helper script on your cluster that can do this for you (delete, re-create with existing permissions etc).
Note that all users will be disconnected when you delete the share. It seems that no users will be affected
isi_smb_ca_share --help
Also note that by design SMB3 server-side copy will not be available when using CA.

You are absolutely right!
I just re-tested this using the script to enable and then disable CA and I wasn't disconnected. I do remember from some testing about a year ago that this wasn't the case, but this could have something to do with that customers environment.
The script basically uses the API to pull the share information, permissions etc and then builds a database of these used to re-create them with the same settings and permissions.

nice script!
are you sure about the disconnection? This is what i would expect but my memories tell me, that under 7.0.x and 7.1.x the share deletion just prevented new Connections but did not affect existing Connections. The "force logoff" could only be accomplished by turning smb off.

On 8.0.0.4
isilonclustername-1# isi_smb_ca_share --help
Must specify either to enable and disable CA!
Usage: /usr/bin/isi_smb_ca_share [--enable-ca|--disable-ca] [--all|--share= ] [--zone= ]
Configure an existing share to either enable or disable SMB3
continuous availablity support. Making a change here will delete and
recreate the share, resulting in a disconnection for all current
clients.

The isi_smb_ca_share command works, most of the time. But be warned, check the share permissions and make sure 1) there are no duplicate permissions 2) all users, groups, SIDS can be resolved.
Collect the current share information with isi smb shares view, in case it fails.
If any are invalid it will delete the share and fail to recreate it, which does not help availability.
