share a given datastore between many Linux VMs using mount points - which FS to use?

Hi

VMWare 6.7 solution here, Using Dell scv2020

Im looking towards making a vmdk, or a datastore avaliable to more than one VM (actually ,20) ,

in order to create a central repository to files between these VMs

Looking throughtly, i did found that its possible to share the same vmdk, as per below

but i will need probably to enable multi writer capability

I do ask if Ubuntu 18.04 GFS2 works out of the box  in this case, or, do i need to look further

for Red Hat or SuSE

I did also found out that OCFS2 could be a good call here.

Is there any other recommended FS in thise case?

Optional – The OCFS2 file system includes a

distributed lock manager and will safely allow multiple

cluster nodes to concurrently block mount shared

storage (Max 32 nodes are supported by SUSE, Max

8 nodes RW limitation per VMware)
