Homelab iSCSI question

LIGISTX

I have ran a TrueNAS VM for years, it’s been great. I’m looking to get a little more advanced both for fun/learning and potentially photo editing off the NAS.

I have a truenas data share shared via SMB and it’s been great as an archive/network location I can hit while remote over WireGuard. I want to retain this SMB share so I can access the data while remote or from other machines… while also going 10gb LAN from my PC direct to the NAS via a direct link using fiber and connectX 2’s. Ideally I would set up iSCSI mount points for my desktop, but I am curious f there is a standard way folks “mirror” data from an iSCSI mount to a truenas datastore shared via SMB. The reason I’m considering iSCSI is for the improved block level performance.

Any recommendations here?

There isn't a good way of doing this other than creating the SMB share on the system mounting the iSCSI block device. You could setup file syncing/replication but then you're doubling up the data.

 

For most situations I have not found much benefit using iSCSI over SMB with RDMA or SMB with Multi-channel, latency for the former and throughput the latter.

 

Really only use iSCSI for something that needs a block device or simply will not run on an SMB share (some really old games just won't).

I wouldnt use iSCSi unless you explicitely need block level access. I use it for creating Datastores on my VMWare hosts using a Virtual iSCSi Adapter. 

But SMB3.0+ with Multi-channel support should give you pretty decent performance relatively close to that of iSCSi

Fair points… I’ll give SMB a shot.
