IC82872: SYSBACK REMAKEVG TRUNCATES OWNERNAME AND GROUPNAME OVER 8 CHARS

APAR status

• Closed as program error.

Error description

• If a Directory or File's ower or group name is over 8
  characters,
  remakevg will truncate the owner or group name causing error:
  
  
  Creating "jfs2" logical volume: grptestlv ..
  Making /grpname/long/tst advance filesystem (jfs2) ..
  chown: 3002-132 abcdefgh is an unknown groupname.
  chown: 3002-132 abcdefgh is an unknown groupname.
  

Local fix

• make this change within /usr/sbin/mkvginfo script.
  
  
  update the mkvginfo script by adding a -X flag to this ls
  command to
  handle over 8 chars
  
  #Get logical volume permissions and ownership
      ls -l /dev/$lvname | read perm x user group x
      uperm=$(print $perm | cut -c2-4)
      gperm=$(print $perm | cut -c5-7)
      operm=$(print $perm | cut -c8-10)
      print LVPERM $lvname $user $group $uperm $gperm $operm >>
  $vginfo
  
      # Get filesystem mountpt permissions and ownership
      if [ "$mountpt" != "-" ]; then
          ls -dl $mountpt | read perm x user group x
          uperm=$(print $perm | cut -c2-4)
          gperm=$(print $perm | cut -c5-7)
          operm=$(print $perm | cut -c8-10)
  
  
  change it to be
  
  
      # Get logical volume permissions and ownership
      ls -Xl /dev/$lvname | read perm x user group x
      uperm=$(print $perm | cut -c2-4)
      gperm=$(print $perm | cut -c5-7)
      operm=$(print $perm | cut -c8-10)
      print LVPERM $lvname $user $group $uperm $gperm $operm >>
  $vginfo
  
      # Get filesystem mountpt permissions and ownership
      if [ "$mountpt" != "-" ]; then
          ls -Xdl $mountpt | read perm x user group x
          uperm=$(print $perm | cut -c2-4)
          gperm=$(print $perm | cut -c5-7)
          operm=$(print $perm | cut -c8-10)
