Equivalent of Synology Hybrid RAID?

[Bassfiend]

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

Hmm...might know a guy...

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.

I havent setup my system yet, but this is a feature I'd love somewhere down the road.

I currently use a Synology NAS as my primary NAS also, 4 bay with  originally 8Tb disks in, I've upgraded 2 drives already to 16Tb ones, so the idea is to use HexOS on a DIY NAS as a backup to the Synology, and utilise the old disks in it, plus more I have already,

I'd end up with more disks in the backup NAS to cover the larger drives in the Synology but it allows me to still use those disks, while also learning more about HexOS and TrueNAS on the backup system to not affecting the main NAS, and get comfortable with it.  Then I'll likely switch to using the DIY NAS with HexOS as the main machine, but by that time I'd be looking to put the bigger disks in that too, so something like SHR would be great.

I am using an aging 4 bay Synology, and adding larger and larger drives was truly exceptional.  The drives did not need to be the same, just larger.  You sacrifice a bit in terms of the storage but you did not need to purchase multiple large drive all at one.  Voting for this feature!

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...

I got my Hex OS system up and running a month or so ago, bought a "nas chassis" from Ali express, that holds 8 drives easily swappable, and used my old gaming PC components, minus the graphics card, to build up a backup NAS.

8*8Tb drives give more than enough space to backup a 4 bay Synology with 2*16Tb and 2*8tb disks in, Allows me to power it up, backup my data from the Synology NAS and then shut it down again (UK based and having another older PC running all the time to just do the odd backup is a little much for power consummation.

Will get more familiar with it and then hopefully I can get more efficient, newer motherboard and CPU, and if we get something like SHR down the road, I could replace the disks and move that to primary.
