Proxmox iSCSI Plugin ready for Testing with 25.10 RC.1

TrueNAS General
1

Community developer @BooMShanKerX has developed a new Proxmox iSCSI plugin based on the new versioned API in 25.10.

The plugin allows a Proxmox cluster to use TrueNAS as the shared storage via iSCSI. The advantage of iSCSI is that VM volumes are stored as zvols and can use very efficient ZFS snapshots.

Thanks for the great work!

This plugin is for testing only… not production yet. If you are keen to help out then post here and let us know.

If you need to use Proxmox with TrueNAS in production now, NFS is the well-validated protocol and does not need a special plugin/api.

Thanks for the great work. I will definitely have a look at this. Will test this soon.

Does this only work with single-controller installations of TrueNAS, or will it work with HA installations? I ask because we are looking at an M-series appliance and would love to use this.

Beta testing is mentioned in the first post. I would not expect it to hit Enterprise for quite a while. No HA.

If you are just Beta testing, you can give feedback, etc.

I only ask because while talking with a TrueNAS sales rep yesterday, he did mention the plugin and didn’t say anything about it not working in HA.

I don’t see why it wouldn’t work. As far as i understand how truenas handles HA, there’s only one controller unit active at a time and if it fails the backup takes over. If smb/nfs/iscsi shares fail over in this case i don’t see a reason it shouldn’t work…

You’re pretty early in the adoption cycle, but yes - we anticipate this will work with HA installations using ALUA failover for iSCSI.
