SMB share limitations

When you create SMB shares, consider their limitations and support restrictions.

NTFS alternate data streams are not supported. For example, named streams generated by a Mac OS X operating system cannot be stored directly.
The encryption status of files cannot be queried or changed from SMB clients. Use the mm CLI commands instead.
When propagation of opportunistic locks across protocols is enabled (SMB option gpfs:leases), then Level 2 oplocks are not granted and Exclusive or batch oplocks are not broken down to Level 2 oplocks and are revoked from the system.
Symbolic links cannot be created or changed from SMB clients and are not reported as symbolic links.
Symbolic links created via NFS or directly in the file system will be respected as long as they point to a target under the same shared directory.
Distributed File System (DFS) is not supported.
Windows Internet Name Service (WINS) is not supported.
Retrieving Quota information using NT_TRANSACT_QUERY_QUOTA is not supported.
Setting Quota information using NT_TRANSACT_SET_QUOTA is not supported.
Setting the maximum number of connections to a share is not supported. The MMC GUI allows specifying this parameter, but it cannot be set on an IBM Spectrum Scale™ cluster.
Unix Extensions are not supported.
You cannot create a shadow copy of a shared folder using a remote procedure call from a shadow copy client. Backup utilities, such as Microsoft Volume Shadow Copy Service, cannot create a shadow copy of a shared folder using a procedure call.
The Branch Cache hash operations using SRV_READ_HASH IOCTL are not supported.
Leases are not supported.
Only the SMB2 and SMB3 protocol versions are supported.
Only mandatory SMB3 protocol features are supported.
No support of dynamic ACLs and SACLs.
No support of SID history.
No support of SMB 3.1.

SMB Clients:

Windows: SMB 1 is not supported, thus no access for Windows XP clients
Linux: SMB1 is not supported, so make sure to use the version option with the kernel SMB client:
```
mount.cifs //fscc-p8-11/ralph /media/ss -o user=aduser1,pass=Passw0rd,dom=W2K8DOM05,vers=2.0
```
