Morning, we would like to create a PV as storage to store Openshift Registry, but the requirement is "ReadWriteMany".
Do anyone know vSan can be used and defined as "ReadWriteMany"? General VMDK are "ReadWriteOnce" only.
Please help, thanks.

Openshift 4.8 vSan - ReadWriteMany used in term of PVC.
@mattyim, basically, no, it can't. Check the official documentation below in the "Table 2. Supported access modes for PVs" about the supported ReadWriteMany block storages:
no there seems to be a limitation with VSphere
vSphere-volume disks are ReadWriteOnce access mode, which means the volume can be mounted as read-write by a single node. See the Access modes section of the Architecture guide for more information.
My research shows that, starting with the vSphere 7.0, release 3 update, vSphere with Tanzu, supports persistent volumes in Read-Write-Many mode.
I have not checked but it could via the file services which will end up to be NFS, what cloudnative workload really needs RWX? it seems to be an anit-pattern. dependency of many nodes to share data from a single file system
