      1. Admin issues
        1.  
          The user password gets displayed in the logs for the Admin> user add username system-admin|storage-admin|master command
      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.  
          Cannot enable the quota on a file system that is appended or added to the list of homedir
        2.  
          Deleting a CIFS share resets the default owner and group permissions for other CIFS shares on the same file system
        3.  
          Listing of CIFS shares created on a Veritas Access cluster fails on Windows server or client
        4.  
          Default CIFS share has owner other than root
        5.  
          CIFS> mapuser command fails to map all the users from Active Directory (AD) to all the NIS/LDAP users
        6.  
          Windows client displays incorrect CIFS home directory share size
        7.  
          CIFS share may become unavailable when the CIFS server is in normal mode
        8.  
          CIFS share creation does not authenticate AD users
      4. Deduplication issues
        1.  
          Removing lost+found files for a mount point that has deduplication enabled may cause issues with deduplication
      5. 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 the security in CIFS is not set to Active Directory (AD), you cannot log on to FTP through the AD user
        5.  
          If security is set to local, FTP does not work in case of a fresh operating system and Veritas Access installation
        6.  
          If the LDAP and local FTP user have the same user name, then the LDAP user cannot perform PUT operations when the security is changed from local to nis-ldap
        7.  
          FTP with LDAP as security is not accessible to a client who connects from the console node using virtual IPs
        8.  
          The FTP server starts even if the home directory is offline and if the security is changed to local, the FTP client writes on the root file system
      6. General issues
        1.  
          A functionality of Veritas Access works from the master node but does not work from the slave node
      7. GUI issues
        1.  
          When both continuous and episodic replication links are set up, provisioning of storage using High Availability and Data Protection policies does not work
        2.  
          When a new node is added or when a new cluster is installed and configured, the GUI may not start on the console node after a failover
        3.  
          When an earlier version of the Veritas Access cluster is upgraded, the GUI shows stale and incomplete data
        4.  
          Restarting the server as part of the command to add and remove certificates gives an error on RHEL 7
        5.  
          While provisioning an S3 bucket for NetBackup, the bucket creation fails if the device protection is selected as erasurecoded and the failure domain is selected as disk
        6.  
          Client certificate validation using OpenSSL ocsp does not work on RHEL 7
        7.  
          When you perform the set LDAP operation using the GUI, the operation fails with an error
        8.  
          GUI does not support segregated IPv6 addresses while creating CIFS shares using the Enterprise Vault policy
      8. Installation and configuration issues
        1.  
          After you restart a node that uses RDMA LLT, LLT does not work, or the gabconfig - a command shows the jeopardy state

          Installer does not list the initialized disks immediately after initializing the disks during I/O fencing configuration
        6.  
          If the same driver node is used for two installations at the same time, then the second installation shows the progress status of the first installation
        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
        10.  
          If installing using a response file is started from the cluster node, then the installation session gets terminated after the configuring NICs section
        11.

        17.  
          When you configure Veritas Access, the common NICs may not be listed
        18.  
          In a mixed mode Veritas Access cluster, after the execution of the Cluster> add node command, one type of unused IP does not get assigned as a physical IP to public NICs
        19.  
          NLMGroup service goes into a FAULTED state when the private IP (x.x.x.2) is not free
        20.  
          The cluster> show command does not detect all the nodes of the cluster

      12. ObjectAccess issues
        1.  
          When trying to connect to the S3 server over SSLS3, the client application may give a warning like "SSL3_GET_SERVER_CERTIFICATE:certificate verify failed"
        2.  
          If you have upgraded to Veritas Access 7.4.2 from an earlier release, access to S3 server fails if the cluster name has uppercase letters
        3.  
          If the cluster name does not follow the DNS hostname restrictions, you cannot work with the ObjectAccess service in Veritas Access
        4.

File system creation fails with SSD pool

The file system creation with layout=mirror operation fails when the pool has SSDs from two or more nodes.

Workaround:

Create the file system using available SAN/DAS disks.

For the disks present in the pool of type SSD, run the following command from the bash shell as Support user to export the disks on all the nodes from where the disks are physically present. 

Support> vxdisk export disk name

After all the disks in the pool are exported from the respective cluster nodes, proceed with the file system creation from the Veritas Access command-line interface.
