Using datastore >2TB


my fileserver is running out of free space so i increased the iSCSI diskspace of my VM to 4TB. But because of the msdos mbr ther are only 2TB available. Now i know the better way to mangage this would be to add a new 2TB iSCSI disk to the ucs VM and not increase the existing one to 4TB. Unfortunatly i can’t shrink the disk back to 2 TB because ESXI doesn’t support this. I found this howto but i have no more space left on the iSCSI device to copy the VM:

Do you have any idea how to manage this?

Kind regards
