Expand local Citrix Hypervisor Storage

Hier onder wordt beschreven hoe een Citrix Hypervisor de local Storage van een RAID1, 5 of 10 wordt uitgebreid binnen een Citrix Hypervisor van +-30GB naar +-60GB. Op een HP Server als voorbeeld zul je eerst de RAID set moeten vergroten als dit gebeurd is kan het volume binnen een Citrix Hypervisor vergroot worden. Dit kan allen als de VM down zijn, de server heeft een Reboot nodig.

Final checks complete. About to write GPT data. THIS WILL OVERWRITE EXISTING
PARTITIONS!!

Do you want to proceed? (Y/N): y
OK; writing new GUID partition table (GPT) to /dev/sda.
Warning: The kernel is still using the old partition table.
The new table will be used at the next reboot.
The operation has completed successfully.
