Why E-Series volume expansion for one volume when using  Volume Group is very slow ?

Last Updated:

Applies to

  • Netapp E-Series
  • Volume Group


Adding capacity to  a volume when using traditional Volume Group instead of Disk Pools can take long time depending of which volume is expanded:
  • If  the expansion is for volume A for example, the new blocks have to be contiguous in traditional Volume Group, so the system will need to reallocate volumes B, C and D to make space for A to grow.
  • If the expansion is for the last volume with contiguous free space, then the system would not need to reallocate the rest.
