This is basicaly what I am hoping to do too ... I have a 4U / 24 bay 19" NAS enclosure (with an 18 Core Xeon and 256GB RAM) and a second 4U / 24 bay 19" expansion chassis that I was really hoping to use in this way, just as a "backup" NAS...

Did did ask this a while ago and the reply I got was encouraging (although understandably non-comittal) rather than dismissive ...

This certainly *USED* to be the case back in the early days of ADSL but nowadays - certainly from my experience in the UK - all the ISPs that I've used in teh last ten years or so don't block ports

TBH I would have thought that the biggest issue would have been that generally any self-hosted email servers tend to get ignored by the rest of the world and emails sent from them filtered/rejected as spam? I've often fancied hosting my own mailserver but have generally found this to be a problem.

I hoped you might... 😉 ...but yes, it would be a very useful facility if it is possible to implement, I'm currently rolling 18Tb drives into the main 8 bay Synology NAS, the two five bay expansion chassis connected to it are getting the 10TB drives that were in the main unit rolled into them at the same time (along with a couple of new 10TB drives so that they both get a full set of five each). The old 4TB and 6TB drives would then ideally be rolled into (what will be) the HexOS NAS which currently consists of 500GB, 1TB and 2TB drives while I'm "playing" with it.

So my aim is to use HexOS as a *BACKUP* server and I have a 24bay 4U case plus a few 24bay Netapp disc shelves and I think I've seen someone on here that is using the 60 drive disc shelves ... I'd hoped that a pool could be set up to at least encompass the whole of the enclosure (I wouldn't dare run a pool across multiple enclosures) but it looks like the maximum pool size is 12 drives, if that is correct then can I ask for the maximum number of drives in a pool to be increased? Cheers Phil

Hi Guys, I currently use a Synology NAS as my main storage solution and Synology Hybrid RAID has allowed that NAS to be upgraded over the years by adding larger drives one at a time. I understand that TrueNAS allows capacity expansion once *ALL* the drives in a pool have been replaced with larger drives but it would be really useful if it were possible to implement something like SHR where a pool could be expanded once the second larger drive has been swapped in and then extended for each additional drive added. Interestingly if you Google implementing SHR under Linux you get "Oh that's just simply..." but no-one seems to have actually done it. 🙂 Thanks Phil
