        14.  
          Continuous replication configuration may fail if the continuous replication IP is not online on the master node but is online on another node
        15.  
          If you restart any node in the primary or the secondary cluster, replication may go into a PAUSED state

Samba ACL performance-related issues

For the ACL improvements to be effective (fewer number of attr nodes), the default mask for creating files and directories is set to 775. Previously, the create mask was set to 744.

If the mask is changed from 775, the ACL improvements may not be effective since the POSIX ACL's calculation changes significantly when the mask changes.

The performance improvements also depend on the file open mode. The current implementation considers normal file open using Windows Explorer or the command window. Samba may calculate a different open mode, depending on the permissions of the parent directory and the actual open request that is issued from the Windows client. These considerations impact the actual performance improvement.
