Verify the continuously available SMB share configuration

To support nondisruptive operations, Hyper-V and SQL Server SMB shares must be configured as continuously available shares. Additionally, there are certain other share settings that you must check. You should verify that the shares are properly configured to provide seamless nondisruptive operations for the application servers if there are planned or unplanned disruptive events.

About this task

You must verify that the two following share parameters are set correctly:

  • The -offline-files parameter is set to either manual (the default) or none.

  • Symlinks must be disabled.

For proper nondisruptive operations, the following share properties must be set:

  • continuously-available

  • oplocks

The following share properties must not be set:

  • homedirectory

  • attributecache

  • branchcache

  • access-based-enumeration

  1. Verify that the offline files are set to manual or disabled and that symlinks are disabled:

    vserver cifs shares show -vserver vserver_name

  2. Verify that the SMB shares are configured for continuous availability:

    vserver cifs shares properties show -vserver vserver_name


The following example displays the share setting for a share named “share1” on storage virtual machine (SVM, formerly known as Vserver) vs1. Offline files are set to manual and symlinks are disabled (designated by a hyphen in the Symlink Properties field output):

cluster1::> vserver cifs share show -vserver vs1 -share-name share1
                      Vserver: vs1
                        Share: share1
     CIFS Server NetBIOS Name: VS1
                         Path: /data/share1
             Share Properties: oplocks
           Symlink Properties: -
      File Mode Creation Mask: -
 Directory Mode Creation Mask: -
                Share Comment: -
                    Share ACL: Everyone / Full Control
File Attribute Cache Lifetime: -
                  Volume Name: -
                Offline Files: manual
Vscan File-Operations Profile: standard

The following example displays the share properties for a share named “share1” on SVM vs1:

cluster1::> vserver cifs share properties show -vserver vs1 -share-name share1
Vserver    Share   Properties
---------  ------  ----------
vs1        share1  oplocks
