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)
