[PATCH docs 1/2] pvesm: mention FC/SAS in the storage overview.

[Aaron Lauterer <a.lauterer@proxmox.com>]

While not a dedicated storage plugin, it is possible to use FC and SAS
attached block storage.

Make it clear that it works and can be used with the snapshots as a
volume chain feature as it needs LVM on top.
