Proxmox cluster 4 node and dell em5024 storage

[indigo.msk]

Dell r650 servers with fibre channel adapter, dell em5024 storage system, configured a proxmox cluster of 4 nodes.
The disks are visible twice in the nodes because they are connected to two controllers, but how do you configure a shared storage for HA?

There are many descriptions of iscsi multipatch for proxmox on the Internet, it does not work for me, I have not iscsi, but FC with a direct connection.
I tried to configure zfc in each node by unchecking add storage, then in datacenter cluster add storage zfs name san-a, yes, storage appeared, each node sees its VM in the storage and if you go to another node there is no vm disk only in its own, this is not correct for HA storage

Hi @indigo.msk , welcome to the forum.

You’re dealing with a classic case of multipath shared FC storage. While our article specifically covers this scenario for iSCSI, the same principles largely apply:

Understanding LVM shared storage

A few more notes:

configured a proxmox cluster of 4 nodes.

You should add a qDevice to make the number of votes in the cluster odd. Otherwise you are risking a split-brain situation if your cluster partitions 2/2.

I tried to configure zfc in each node

ZFS is not a suitable file system for Clustered Shared Storage. Your primary and officially supported option is Thick LVM (see article above).

I have not iscsi, but FC with a direct connection.

If the article is iSCSI centric, you can skip the steps for connecting/presenting the LUNs to the host. Start from the Multipath portion of the article.

Keep in mind that the best source for Multipath configuration steps is your storage Vendor. Most have a document outlining appropriate configuration for their FC storage with a Linux client.
