Error description

  • Tivoli Storage Manager Backup & Archive Client supports backup
    and restore of Linux extended attribute like Linux
    security.capability.  However, the client may fail to restore
    the  security.capability set on a non-empty file.
    
    .
    L2/Customer diagnostics:
    
    1: security.capability. was set on a non-empty file:
    
    # getcap tcpserver
    tcpserver = cap_net_bind_service+ep
    [root@ganesh source]# attr -l tcpserver
    Attribute "selinux" has a 28 byte value for tcpserver
    Attribute "capability" has a 20 byte value for tcpserver
    2: perform a backup of the file:
    dsmc i tcpserver
    ...
    Normal File-->             9,907 /var/scratch/source/tcpserver
    [Sent]
    Successful incremental backup of '/var/scratch/source/tcpserver'
     ...
    
    3: perform a restore of the file:
     dsmc restore 'tcpserver*' /var/scratch/restore/
    ..
    Restoring           9,907 /var/scratch/source/tcpserver -->
    /var/scratch/restore/source/tcpserver [Done]
    ..
    4: verify the attribute after restore:
    [root@ganesh source]# attr -l
    /var/scratch/restore/source/tcpserver.c
    Attribute "selinux" has a 28 byte value for
    /var/scratch/restore/source/tcpserver.c
    
    Note: the "Attribute "capability" is missing after the
    restore
    
    
    Version /Platform affected:
    Tivoli Storage Manager Client on Linux all supported platforms
    .
    Additional KeyWords : attribute capability
