Cluster FS (Analogue of VMFS, Cluster Share Volume) on Linux?

Question

linux

I'm looking for an approach to solving a well-known problem - organizing a shared storage for a cluster of hypervisors. There is an iSCSI target, there is a LUN on which virtual machines will lie. It is necessary to somehow organize competitive access to one block device from different servers.
On VMWare, this is solved by the presence of VMFS. Microsoft has a Cluster Shared Volume. How is this task usually solved on linux? Here you can directly poke your nose into a suitable manual. I could not google anything intelligible, it looks like I'm asking something wrong.

There is an incomplete list of clustered FSs here.

You can try to study the advantages and disadvantages if you are not advised anything specific.

Answer 3

Well, give this LUN directly to hypervisors via iSCSI. They usually figure it out on their own. ESXi, Hyper-V, KVM themselves understand that if iSCSI storage, then they are not alone on this moon, and work accordingly.
Or, if you also need to see the virtual machine files themselves for some reason, distribute the datastore over NFS.
