I am setting up a small virtual environment and I'm using a pair of Windows (HyperV) hosts and a Synology 54TB NAS for the VM storage.
I know I cannot use the same iscsi path for 2 concurrent hosts, as they will not be aware of each other and will overwrite each others files and cause problems.
What I have done instead is this...
I've created 1 LUN that is 54Tb in size, multi-connections enabled.
I have added this Iscsi target to both hosts.
I have created a 10Tb partition, labelled HOST1 and mounted it with a drive letter on Host 1.
I've also created another 10Tb partition, labelled HOST2 and mounted it with a drive letter on Host 2.
Neither of the Windows servers have the other servers 10Tb partition mounted.
As far as I can tell, I should avoid the problem of having the two hosts overwrite each others files, however I wanted to gauge opinion on this before a start using the environment incase there are pitfalls I have not thought of.
