IT29083: ANS1071E OR ANS1149E MESSAGE LOGGED WHEN ATTEMPTING A BACKUP OF A LINUX SYSTEM

APAR status

• Closed as program error.

Error description

• ANS1071E Invalid domain name entered is seen when trying to
  perform a scheduled incremental backup, the domain name shown in
  the ANS1071E is not a valid mount point name and may not be
  consistent, different invalid names may be displayed.  A manual
  backup displays an 'ANS1149E No domain is available for
  incremental backup. The domain may be empty or all file systems
  in the domain are excluded. ' message instead of the ANS1071E
  message.
  For example:
  ANS1071E Invalid domain name entered: 'Pj¦
  Note that the name logged isn't consistent:
  ANS1071E Invalid domain name entered: '···'
  ANS1071E Invalid domain name entered: ' p4'
  ANS1071E Invalid domain name entered: ' ··'
  Customer/L2 Diagnostics:
  A service trace will show that It appears that the client is
  'interpreting' the FS mount point as something else.  The FS
  mount point of / for root appears fine in the mount listing from
  the trace:

  But, when adding the filespace, '/' has become '·5'.

  This behavior occurs due to duplicate mounts in the /etc/mtab
  file.  The duplicate mounts in /etc/mtab results in a  /etc/mtab
  size which is larger than the /proc/mounts size, causing  the
  mount table inside the running SP client process to become
  corrupted.
  
  Initial Impact:
  
  Tivoli Storage Manager Versions Affected: 81L
  
  Additional Keywords:

Local fix

• Review the /etc/mtab file and remove any duplicate mounts to
  avoid /etc/mtab being larger than /proc/mounts.
