Hi everyone.
I'm a teacher from a High School, I teach vocational training. I would love for my students to learn Proxmox.
I am using proxmox on fujitsu rs300 s6 with a LSi SAS controller.
I created a raid 1 on LSI configuration and installed proxmox VE 7.2 on it with default options and ZFS format.
the local node it’s ok but de local-ZFS it's work and received a error “could not activate storage 'local-zfs', zfs error: cannot import 'rpool': no such pool available (500)”

Please, help me!! i’m try to find solutions but didn’t find it.
Thanks.

P.S.:this is some information about my computer.

Hello,

Are both nodes are installed on ZFS?


Can you please also post the output of the `systemctl status zfs-mount.service` command?

Thanks for your help Moayad
Both server have same configurations.

What do you recommend me? reinstall servers and use ext4?

That depends. Sounds like you are running a 2 node PVE cluster? Maybe with ZFS replication for HA? ZFS replication of cause wouldn't work without ZFS.
You also need at least 3 machines for a cluster, or otherwise you run into a split-brain situation once one of the two nodes will fail, so the whole cluster will become unavailable.
You should at least add something small like a thin-client as a qdevice as a third voter: https://pve.proxmox.com/wiki/Cluster_Manager#_corosync_external_vote_support

If you really want to use ZFS I would recommend ditching that raid controller and getting a LSI HBA card. Sometimes its also possible to switch that raid card into an HBA mode or to flash it from a IR-mode firmware to a IT-mode firmware, so the raid card becomes a dumb HBA.
