New cluster - now missing "Content" tab

[holckj]

I recently created a small cluster, only 2 servers and a Raspberry Pi acting as quorum device. Things went smoothly, but now I seem to be missing the usual "Content" tab when looking at my storage:


There is no "Content" tab to be found, neither for the Datacenter or the servers. Both servers use zfs for filesystem, but in different configurations. "lasse" has 4 HDDs, hda mirroring hdb, and hdc mirroring hdd. "sonja" has 3 HDDs, mirroring each other.

The file /etc/pve/storage.cfg on both servers looks like this
dir: local path /var/lib/vz content backup shared 0 zfspool: local-zfs pool rpool/data content rootdir,images sparse 1 dir: intenso path /mnt/intenso content backup prune-backups keep-last=1 shared 0

Have I done something wrong?

Hi,
nothing wrong. The Content tab has been split up into the individual contents like VM Disks and CT Volumes.

Thanks for a quick reply, but I can't find a Content tab anywhere. For one of the nodes, "lasse", nothing shows under VM Disks and CT Volumes:


The other node has a VM Disk, but show no Content tab:

I meant, that there is no Content tab anymore, because it has been split up into multiple ones. What do you expect on node lasse, isn't this a new installation? What does zfs list show there?

I'm sorry for my late reply ... It seems I don't really understand how to handle storage in a cluster. I thought that with a lot of free disk space on node "lasse", it would in some way be possible for me to use this space for shared storage. Most of the disk space on "lasse" is used for a zfs. What can I use this space for, except for VMs?

Can you point me in a direction where I can find an introduction to how to handle storage in Proxmox?

The official documentation is here. While you can set up ZSF/directory storages/Ceph/LVM via Proxmox VE GUI, a shared storage (that's not Ceph) needs to be set up manually first. Once set up, you can add it to Proxmox VE's storage configuration, to be able to use it.

If you have a ZFS you want to share you might want to take a look at ZFS over ISCSI (likely a bit outdated in general, but the part about the ssh keys/config is most important) and LIO (for setting up the target).

Thanks again - the number of options is really overwhelming I have this small cluster, only 2 "real" nodes and 1 "quorum" node on a Raspberry Pi. What I really want is to be able to share storage between the two "real" nodes, so I can easily move VMs between the two nodes, and also have one of the VMs running as HA (High Availability). Is this possible? What's your recommendation for a Proxmox newbie like me?

For proper HA, you need at least three nodes. And if you export the storage from one node that node is of course still a single point of failure. In your case, I'd recommend using ZFS with replication (replication needs to be set up for each guest, pool needs to have the same name on both nodes), which can be used for HA managed guests.
