Why does E-Series Volume Group volume capacity increase take such a long time?
Applies to
- NetApp E-Series
- Volume Groups
Answer
Adding capacity to a volume when using traditional Volume Group instead of Disk Pools can take long time depending of which volume is expanded. From SANtricity > Operations in Progress, it shows weeks or even months before completing the capacity increase
- 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.
Additional Information
- Add capacity to a Disk Pool or Volume Group
- The volume capacity increase process needs to be finished before space can be seen on the host
