pronto Posted January 24, 2019 Share Posted January 24, 2019 Hey all, 7 days into the Unraid trial, I have: a old dual core 2ghz cpu 2 GB RAM 1x 6TB parity 2x 2TB 1x 1TB 1x 500GB cache I've tried to set up Plex, NextCloud, DelugeVPN, Sonarr, Radarr, Lidarr and Jackett all running at the same time, but the OS would hang/crash all the time, take forever to do the simple tasks. It's a dual core 15+ year old machine, it just can't handle everything at once, I get it. Not Unraid fault. I randomly posted to the local Buy/Sell and got a ASUS G73S laptop, I7, 8GB RAM (for free 😀) and that got me thinking. Is it possible to have the dual core machine souly for the purpose of being the HDD "holder" and use Unraid on the laptop, but have Unraid use the drives as if they were locally mounted (sdd, sde, sdf...)? Trying to stay on the DIY/free side of things, as the laptop only has 1 USB 3.0 slot. Any thoughts or options? Cheers Quote Link to comment
jordanmw Posted January 24, 2019 Share Posted January 24, 2019 You could setup an iSCSI target server with the drives mounted there, then present the iSCSI target to the virtual machine- that would still work. Quote Link to comment

Interesting, I'll look more into that... My potential thoughts were: Ubuntu server on HDD machine (or something less resource intensive, mind you Ubuntu worked pretty well before) UnRaid on the Laptop Set Ubuntu to share the "/dev" folder to only the laptop IP (I static IP my network) Mount the remote "/dev" folder to "/devremote" on the laptop Within fstab on the laptop, define the drives as sda, sdb, sdc, etc... I tried searching for such a setup on these forums and google, but haven't come up with anything, mind you I'm most likely using the wrong terminology. Quote Link to comment
trurl Posted January 24, 2019 Share Posted January 24, 2019 This is so totally unlike Unraid that I wonder why you want Unraid involved at all. What specifically do you want Unraid to do for you that you can't do with some linux distro? Quote Link to comment
pronto Posted January 25, 2019 Author Share Posted January 25, 2019 I'm trying to work with what I got. No surplus of money for parts. The G73S only has a single 3.0 port. The hard drives I have are all SATA connections and I don't have a hub or SATA-USB adapters. I have only trialed UnRaid for a few days, but I like the UI, the simplicity, and how easy things go together. "One stop shop", if you will. If I'm able to configure with the components I have, I will undoubtedly purchase a license. I know its completely out of the norm for a setup like this, but would my "idea" be feasible? I'm going to have a try at it on my own, but if you have any tips or ideas to assist, I would be greatly appreciative. Quote Link to comment
pronto Posted January 25, 2019 Author Share Posted January 25, 2019 Also, having this set up like this would still allow me to use parity and protect my drives/data whilst utilizing the processing power of a i7, vice a 15+ year old dual core. Quote Link to comment

I think it would be way more trouble than it is worth, even if it were possible, which I doubt. And nobody is going to be able to help you do it. Quote Link to comment
trurl Posted January 25, 2019 Share Posted January 25, 2019 And I can't imagine that it would perform any better than what you have with just the old system by itself. There is a lot more to this than just the CPU and RAM. All the storage stuff is mostly limited by I/O, which is going to perform a lot worse over the network between the machines without special and expensive hardware. Quote Link to comment

Regardless of your equipment this is is not going to work as the device "files" are special files that cannot really be opened in a meaningful way across the network. If I were you I'd sell the free laptop and use the money to buy a better server - just about anything you get will be better than what you have, but what you really need is a lot more memory. Linux is very memory efficient but what you want to run won't even fit in 2G of RAM, even if I had the latest i9 on hand. 2G of RAM will not even allow you to upgrade Unraid automatically.

jordanmw Posted January 25, 2019 Share Posted January 25, 2019 Just a suggestion, seemed like he was looking to play around.... connectivity would be the hitch, just thinking if ways to make it work, mtu comes into play and you would spend money and time making things work that are possible, but not designed to. Up to you, but... lots of work. Quote Link to comment
pronto Posted January 25, 2019 Author Share Posted January 25, 2019 I was just looking to play around. See if I could make it work with what I got. Thanks for the input guys, I'm going to try a few different things and see what works best. Its mainly just going to be a Plex server with download capabilities and NextCloud support for personal files. Max simultaneous connections should be 5 at most, 2 local and 3 remote. I suppose I'm thinking a bigger picture than what I actually need. Cheers Quote Link to comment
trurl Posted January 25, 2019 Share Posted January 25, 2019 Just save yourself the time, frustration, and money trying to make this work. You'd really wind up having to write your own system and Unraid wouldn't really be part of it. Plan and save if necessary to do a reasonable build. Quote Link to comment
pronto Posted February 5, 2019 Author Share Posted February 5, 2019 (edited) Sorry to res this one back up, but i finally found the terms i was looking for to do what i want to do. Have a ubuntu machine with all my drives, and using either iSCSI or NBD (Network Block Device) push the /dev/sd* to unRAID. I've bee searching for a way for unRAID to be an "iSCSI initiator", but i can't seem to find any documentation to add it to Slackware. I've tried to install NBD via https://slackware.pkgs.org/14.1/slackonly-x86_64/nbd-3.12.1-x86_64-1_slack.txz.html, but i am having issues with dependancies that i cannot figure out. (install libidn.so.11?) I know this is not what is generally used in unRAID, but im looking for any assistance i can get. Edited February 5, 2019 by pronto missed iSCSI Quote Link to comment
trurl Posted February 5, 2019 Share Posted February 5, 2019 Unraid is a very stripped down slackware and will be missing many things included in a full slackware development environment. In addition to this, some of the lower level details relating to the parity array and user shares is custom code. Have you installed Unraid on your laptop? I think you are going to have a pretty hard time even getting to a point where you can try to work on this. Quote Link to comment
