Creating SMB share

Use the following information to create an SMB share:

Create the directory to be exported through SMB:
```
mmcrfileset fs01 fileset --inode-space=new
mmlinkfileset fs01 fileset -J /gpfs/fs01/fileset
mkdir /gpfs/fs01/fileset/smb
```
Note: IBM® recommends an independent fileset for SMB shares.
Create a new independent fileset with these commands:
```
mmcrfileset fs01 fileset --inode-space=new
mmlinkfileset fs01 fileset -J /gpfs/fs01/fileset
```
If the directory to be exported does not exist, create the directory first by running the following command:
```
mkdir /gpfs/fs01/fileset/smb"
```
The recommended approach for managing access to the SMB share is to manage the ACLs from a Windows client machine. To change the ACLs from a Windows client, change the owner of the share folder to a user ID that will be used to make the ACL changes by running the following command:
```
chown 'DOMAIN\smbadmin' /gpfs/fs01/fileset/smb
```
Create the actual SMB share on the existing directory:
```
mmsmb export add smbexport /gpfs/fs01/fileset/smb 
```
Additional options can be set during share creation. For a list of all the supported SMB options, see the mmsmb command.
Verify that the share has been created:
```
mmsmb export list 
```
Access the share from a Windows client using the user ID that has been previously made the owner of the folder.
Right-click the folder in the Windows Explorer, open the Security tab, click Advanced, and modify the Access Control List as required.
Note: An SMB share can only be created when the ACL setting of the underlying file system is -k nfsv4. In all other cases, mmsmb export create will fail with an error.
