Hello, I have an installation running with LVM on iscsi, everything was working normally but suddenly the VG called storage disappeared, I have a Dell ME5084 storage configured with multipath, in which I have two volumes that I present to my proxmox cluster and only one Of the two that are causing problems and the storage has no problems, the only thing I did several months ago was update from version 7 to version 8 and they changed the names of the network cards that I had connected to the storage, I changed them and everything was working. The volume group that desappeared is called "almacen". i ran those commands:
