Thank you very much, thats the answer i needed. I have modified it without any problem. For anyone else who needs more documentation: psonlinehelp.equallogic.com/.../ModifySizeOfNASReserve.htm I could find this document with your answer. Thanks again!
Dear ..,  We have just installed the FS7610 NAS heads as an extension to our PS 6110 Equallogic cluster. Now maybe a stupid question, but im going to ask it anyway. Our NAS cluster only has 791 GB allocated. As we are creating containers that exceeds this 791Gb, we need more space. Normally when you grow a LUN you go to modify setting, only for the NAS LUN's there is no option to grow. How to proceed from here?
