pve-fcsan 1.4.0

New array driver: Fujitsu ETERNUS DX S5 / AF S3 (fujitsu-eternus), also covering DX8100/DX8900 S4. It uses the ETERNUS RESTful API on HTTPS port 5665 and follows Fujitsu's ETERNUS RESTful API Reference (P3AG-5492).

• Needs controller firmware V11L40 or later, with the RESTful API enabled and port 5665 open in the array's firewall settings. An upgrade from older firmware closes that port.
• The API has no host groups, so each node HBA port is registered as an FC host (<node>_<n>). Each volume is connected to all of them with one host LUN that is free on every host. The array chooses the CA ports: every port with host affinity enabled that the WWN is logged in to.
• Mapping is refused if a cluster host shares its LUN group with a host outside the cluster.
• Volumes are created in thin provisioning pools, thin or thick. Grow, delete and linking existing datastores work as with the other drivers.
• New t/66-eternus.t (356 checks in total).

A driver is optional. If you create and map LUNs yourself, add no array: pve-fcsan discovers the LUNs, sets up multipath and builds the datastores on any FC or iSCSI array. The README now says so.

Still beta: the ETERNUS driver has not run against a real array yet. Try it with a 10 GiB test datastore first and report what you find.

Install or upgrade on every node:

apt update && apt install pve-fcsan
