Fibre channel storage and LVM. Problems

[aibat]

We assembled a cluster of 10 servers and connected the storage system using the Fiber channel protocol. Created moons and connected them to our cluster.
We connected the disks to the cluster using multipath.
We created virtual machines and provided disks from the moons data, decided to conduct an experiment and decided to migrate our VMs between the cluster nodes, the following error occurred:

Please help solve this problem.

P / s: I'm sorry, but I have difficulties with the English language, so I translate with the help of a translator

It's been a long time since my last FC deployment, but seems as if you forgot to flag the FS storage as "shared" in Proxmox.


The error message seems to describe that Proxmox is trying to create a copy of the LVM on the other node, using the same storage and overwriting the same LVM volume used by the currently running VM.

When you flag a storage as Shared, you let Proxmox know that it should be able of accessing the data of a storage from any node that has that storage configured, so it wont try to make that copy to migrate VMs.

I have these VGs and settings installed.
