We have a legacy platform running on VMWare with an NFS SAN. If/when connectivity is lost between the cluster and the SAN we get to experience resolving disk issues across several hundred VMs. Yanking access to the underlying storage device creates the most frustrating array of issues in Linux, depending really on the workload on the server. By far the most common is the mount becomes read only, forcing a reboot, which halts in order to fsck. Windows on the other hand just resumes from where it left off, or sometimes reboots but is usually clean.

This platform is currently being retrofitted with vsan.
