      2. Backup issues
        1.  
          Backup or restore status may show invalid status after the BackupGrp is switched or failed over to the other node when the SAN client is enabled
      3. CIFS issues
        1.  
          Deleting a CIFS share resets the default owner and group permissions for other CIFS shares on the same file system

        4.  
          Listing of CIFS shares created on a Veritas Access cluster fails on Windows server or client
        5.  
          Modifying or adding a CIFS share with non-default fs_mode/owner/user options results in these settings getting applied to all the existing shares on the same path
        6.  
          CIFS> mapuser command fails to map all the users from Active Directory (AD) to all the NIS/LDAP users
      4. Deduplication issues

        1.  
          Error while setting full access permission to Enterprise Vault user for archival directory
      6. FTP issues
        1.  
          If a file system is used as homedir or anonymous_login_dir for FTP, this file system cannot be destroyed
        2.  
          The FTP> server start command reports the FTP server to be online even when it is not online
        3.  
          The FTP> session showdetails user=<AD username> command does not work
        4.  
          If there are more than 1000 FTP sessions, the FTP> session showdetails command takes a very long time to respond or hangs
      7. GUI issues
        1.  
          When both volume-level and file system replication links are set up in Veritas Access 7.3, provisioning of storage using High Availability and Data Protection policies does not work

        7.  
          If the same driver node is used for two or more installations at the same time, then the first installation session is terminated
        8.  
          If you run the Cluster> show command when a slave node is in the restart, shutdown, or crash state, the slave node throws an exception
        9.  
          If duplicate PCI IDs are added for the PCI exclusion, the Cluster> add node name command fails

Erasure coding for Object Store buckets

Erasure coded (ecoded) file system is added as a technical preview feature in Veritas Access. Erasure coding offers a more robust solution in redundancy and fault tolerance for critical storage archives. It is supported in DAS, SAN, FSS, and standalone environments. ObjectAccess buckets can be created to use erasure-coded volumes.
