Increase size of sparsebundle for TimeMachine I am using a sparsebundle store on a linux server. It worked well until today. 

Today Time Machine tells me that the size of the sparsebundle (500gb) is not sufficient. So I use hdiutil command for increasing the size of the sparsebundle: hdiutil resize -size 600G xxx.sparsebundle. The command works fine but Time Machine seems to not see the increase of the size of the sparsebundle (it only sees that the size is 500gb and so it can't continue to backup).

Do you have any idea for solving this issue? 

NB: 


the sparsebundle is encrypted
Time Machine mounts automatically the sparsebundle (linux server configured with afp and netatalk).

BuildVersion:    14B25
Double-click the sparse bundle to mount the Time Machine Backups or Backup of &lt;computer name> partition (but don’t select it). That may take a moment.
  Select the sparse bundle again, and click the Partition tab towards the top of the
  window.
  
  
  Type the desired size in the space provided, or, in the diagram that appears, drag the lower right corner of the partition all the way to the bottom to fill the volume, or drag it upwards to shrink it, click Apply and confirm.
  As part of the process, Disk Utility will do a verification of the data in the partition, so it may take quite a while. You can see the log of what it's doing by selecting Window > Show Log in the menubar.
  When done, and you quit Disk Utility, you may get an Operations still in progress message. As long as the log says "Partition Complete," it's done, so click Close.
  Eject the sparse bundle before starting the next backup.
