Resize LUN error in Storevault Manager
If you are trying to resize a LUN on your Netapp Filer and recieve the following error:
error 28: insufficient space to grow this volume with its guarantee enabled
Make sure that you have enough available space on the volume by running the df -h command. Once you have determined that you have enough space to grow your LUN then you need to run the following command, vol options ‘LUN NAME’.
Have a look at the results and check to see if you can find guarantee=volume. If you can then you will need to change this value to none by running this command vol options ‘LUN NAME’ guarantee none. Run the vol options ‘LUN NAME’ again and now you will see guarantee=none, you can now resize the LUN in Storevault Manager.
Ensure that you change the setting back to gurantee=volume by running the following command vol options ‘LUN NAME’ guarantee volume
This issue can also be related to the StoreVault enabling snapshots EVEN THO StoreVault Manager (SVM) reports that they are off. Quick fix is to…
1) Make sure snapshots are off on the LUNs
2) Telnet to the SV
3) use “df -h” to check LUN sizes. If you can see that LUNs are grabbing more space than allocated, then follow the procedures from here…
