TrueNAS At Home - Redundancy / (HA?)

[TubsAlwaysWins]

So I finally got TrueNAS running at home. Technically I have 2 instances of TrueNAS running at home.

One instance is running on a HP Prodesk 405 G4. The other is running on a Dell OptiPlex 7050 micro. The limitation here is that neither offers alot of great options for storage, expecially redundancy (Thats where the 2nd instance comes in - kind of).

Both have whatever M.2 / NVME SSD I had laying around that TrueNAS boots off of, and then I cannibalized and crammed (CRAMMED for the HP) a 4tb drive from a external HDD inside each for mass storage. 

So where does that leave me? With no redundancy and 2 machines that consume 1/3rd the power of my R610. 

 

So now im here. Obviously I would prefer to keep my data redundant. I technically am I think. I have a snapshot / replication task cloning my entire 4TB Dataset from NAS1 to NAS2.

NAS1 Exists as a file store, and runs some Plugins / VMs. 

NAS2 Exists to backup NAS1. 

 

The catch with this (for me at least) is data recovery, if I needed to. It wouldn't be pretty.

 

Wondering if there is a better, more elegant way I should be doing this. Ideally if I could set them up in HA I would but I think I need TrueNAS Enterprise for that. 

Any thoughts? It would be great if my plugins and jails were always ready to go, etc. 

 

Thanks

Sounds like you have an extremely convoluted RAID1 spread across 2 systems instead of contained in a single system.

 

Easiest solution I can think of is to set up a single dedicated machine that can hold several hard drives, and configuring that as your NAS, probably with a RAID10 array(RAID0 nested in a RAID1).

For truenas to really do anything useful, you need multiple drives in a ZFS array. Without an array, ZFS is really not much different than any other file system as it can't do any of its "magic".

 

I would figure out if either of those mobo's are standard ATX, and if so, transplant into a more normal case, and throw harddrive in it. If not, I would honestly look for some used parts and build a modest little PC to run truenas on. Doesn't need to be much, just needs to fit in a standard case that can accomadate more drives.

Ya no far from standard ATX. Both are SFF units. 

 

I have a T330 sitting around I could use, wonder what the power usage is.

Depending on the installed hardware, I'd guess sub-100 watts idle.

 

My NAS / home server is an R730XD with a dozen hard drives. (A very similar, 2-socket LGA2011-3 platform.) It idles at around 200 watts.

Know how much it affects your power bill? I mean it cant be that much but im at 50w across the 2 systems now. 

I think I pay $0.1083 per KwH. 

One reason it isnt on my R610 is because it idles at like 170W. Id care less if it had more umph but here we are.

I pay about $0.16/kWh so I think it comes out to around $30/mo. For what it does (mostly Plex and file storage), I think it's worth it.

 

Yeah, Nehalem and older really aren't worth running "in production" anymore. Sandy Bridge was a huge leap forward in terms of performance per watt, then Haswell improved on that and doubled the density.

I cry in .40+ per kWh…
