Reserved DHCP = the client device is still set to get its IP via DHCP, but the DHCP server (your router, etc) will always give that device the same IP every time. Static IP = the client device is set to a specific IP address and never asks the DHCP server for one. This is a problem if the static IP is within the range the DHCP server can assign within.

Okay it's definitely the former, since it is all done by the IT people without any access to the server in question. So, now that I have it set up and home, is there anything I absolutely must enable to be able to access it back at school? It seems like the issue was only at the "discovery" stage, now that the OS is installed the only potential impediment to access will be that the University has properly set up reserved DHCP. But I want to make sure there's nothing that I may be missing. E.g. do I have to set "static IP" to match the reserved DHCP address the University will assign when I plug it in back in?

No, if you're connecting it to a network with DHCP, you should just set it to DHCP and not define a static IP.

Also in the case of the eventual "problem must be on your end" response that doesn't actually answer my questions. Bringing it back to school tomorrow, we shall see. And I'm sorry to maintain my ignorance but what doesn't make sense? If the "request an IP address" procedure doesn't require you to change any settings on the machine in question, then by IOwnCalculus's explanation it must be reserved DHCP and not static IP. Since static IP would be a setting on the machine in question and DHCP would be on the network end. What am I missing? SurgicalOntologist fucked around with this message at 03:09 on Jan 13, 2015 |

You don't know how they are configuring their network. There are two possibilities, which IOwnCalculus described: 1) They give you a reserved DHCP assignment. Your NAS is configured for DHCP and it picks up the reserved IP and you're done. 2) They give you a static IP assignment. Your NAS must be configured for that IP manually. It will not propagate with DHCP. I believe that the latter is the more common arrangement. At least, it has been in my experience. sleepy gary fucked around with this message at 09:26 on Jan 13, 2015 |

I'm 'serving' all my files and media from my old desktop. It's just running plain Win7 with windows shares, plus plex server, mysql xbmc db, sab etc. It's an i3 530, 4gb RAM (non ECC) with 4-5 various brand dives plugged in. No redundancy at all. If I say I'm not going to buy any new hardware besides HDD, would switching to freenas et al+ZFS still be recommended despite the none server specific hardware and non EEC RAM? I'm guessing ZFS /without/ ECC RAM is still better than ntfs with no redundancy and ECC? If I do switch, is there a direct way of incorporating old disks with data on, or will it be a case of buy new disks, initialize them in the ZFS pool and then transfer across the existing data and then format and add the existing drives?

Pretty much anything with redundancy (like mdadm, old hardware raid cards and any other solution) is better plain NTFS formatted drives, but its important to remember that there are very good reasons to use ECC to avoid the silent data corruption that can happen - however, its totally up to you.

Note that ECC RAM has always been recommended even before ZFS, it's just that people tend to start getting some false senses of security just because they're using ZFS. I've experienced some corruption on software RAID before using non-ECC RAM. With ECC, it should also be noted that you may get MORE crashes rather than fewer - ECC flags uncorrectable errors in a way that your OS should notice and kernel panic or whatever else for a fatal error. I have several dozen ECC checksum errors recorded in my BIOS, and I really don't want to know what would have gotten screwed up if it had gotten through.

Is there any point to putting FreeNAS on a ThinkServer TS140 if I'm not going to be really using it as a NAS? I'm mostly going to be using it as a dedicated Plex server, though it will house all my media files. They're not mission critical, and I'm not really inclined to drop a bunch of cash to get enough disks to set up a raid of some sort, so the machine is going to have a 1TB boot drive and a 3TB Western Digital Red for media storage. I might pick up a second identical WD Red, but that would be later once my storage runs out. Would I see any benefit to using FreeNAS, or should I just slap my favorite flavor of Linux on there and call it good?

If you're not going to bother with ZFS, there's no real reason to bother with it, other than that you can be up and running with a "basic" setup quite quickly. Especially if there's something you might want to use it for or some program you might want to run that isn't really supported (eg, maybe you want to toss some chat or game servers on there).

Not really NAS per se, but the elderly desktop machine I use(d) as a media server finally just quit working yesterday. Because I am lazy and have safe backups of everything anyway, I use pooled disks in Windows that show up as one big network drive. Because I am lazy (did I mention that?), on a whim I slapped the three pool disks into a different machine, and discovered that Windows has explicit options in Disk Management to import "foreign" drives and will happily reconstruct your previous pool and retain your data. I just thought that was pretty neat, since now I don't have to spend the extra time restoring everything from the backups. Once I get a new "server" cobbled together (someday I'll be able to afford a proper one) I can just transplant the disks again and go on my merry way.

DrDork posted:Until a disk fails. *knocks on wood* Yeah, there's always that. I do have backups though, as I said, and there's nothing that couldn't be otherwise replaced given a little (OK, a lot of) time and effort of re-ripping a bunch of disks. I was already pretty much resigned to a restore-from-backup anyway, and just pleasantly surprised that everything worked out as well as it did... this time. On the upside, the replacement computer is a newer (than the dead one) machine that was just given to me a couple of weeks ago because it was "broken." One replacement video card later and it fired right up. It's an i5-640 with 8 gigs of RAM - I can only imagine that someone paid way, way too much for it when it was new. Just wish it had more than 4 SATA ports. And more drive bays. And was 4 years newer. And was a completely different computer, really. But fuck it, it was free and I'll take what I can get right now ![]()

The minimum RAM for FreeNAS+ZFS is 8GB... so it's pretty much out of the question if you aren't buying new hardware. Non-ECC+ZFS means that ram errors can destroy your pool instead of just corrupting some files. If you make a vdev with new disks, transfer your data over, and then add the old drives, the old drives have to be on a new vdev. Have you looked into StableBit DrivePool? I think you'd be happier with that. It will be much easier to just throw everything together and get it working without shifting data around, and you can just assign redundancy where you want it. It's what I would have done if I hadn't invested in the server hardware already. AgentCow007 fucked around with this message at 16:15 on Jan 17, 2015 |

I've been using 5 3TB hard drives on my main desktop with FlexRaid for a few years, and I mostly like it, but I'm considering moving the storage to a dedicated FreeNAS+ZFS box. However, all my spare hardware is on the other coast, so other than theoretically reusing my consumer-quality 3TB drives, I'd have to start from scratch. Would the following seem like the cheapest possible way to build a server that's storing/distributing media 90% of the time it's working? I'd like to be able to fit at least 5 drives, ideally more. Rosewill Challenger case (http://www.newegg.com/Product/Produ...N82E16811147153) - $50 Cheap motherboard/processor combo from Newegg (http://www.newegg.com/Product/Combo...t=Combo.2141270) - $67 8GB RAM (hhttp://www.newegg.com/Product/Prod...N82E16820231428) - $63 [Alternative: http://www.newegg.com/Product/Produ...N82E16820239370 $90 for EEC RAM] 500W Corsair PSU (http://www.newegg.com/Product/Produ...N82E16817139027) - $30 after rebate Total (leaving out hard drives, obviously): $210 Am I likely to do better than that for that cheap? I guess the main sacrifice there is the size of the machine, but I might be able to find a big empty closet for it to sit in with a LAN connection. berzerker fucked around with this message at 21:54 on Jan 17, 2015 |

From what I've heard, AMD stuff does not play nice with FreeBSD/FreeNAS. I would probably go for a celeron or one of those new multi-core atoms to stay on the cheap. I also cant find anything about that board supporting ECC, so it probably doesn't.

I was about to recommend the Thinkserver if your budget and requirements are so tight that you can't really spend more than several hundred to put together something that's easy to maintain and power + space efficient. The Silverstone DS-380 is alone within striking range of the Thinkserver, for example, and you still need motherboard, CPU, RAM, and a PSU. This is fine and dandy if you have some spare parts lying around to create a FrankeNAS, but a lot of people really don't.

That M1015 looks like it adds $200 to the mix, though, hardly inconsequential. I guess I could just get a PCI-E SATA card for $15-30 and add drives that way, though, and let the software handle the RAID. Also, ugh, looks like I'll be moving again in a few months, so I guess time to hold off on this until I don't have to pack everything into my small car and head across the country again. So false alarm, but thanks for the advice.

The M1115 is basically the same as the M1015 and can be flashed with the exact same firmware. If you can grab one for $60 then I'd say go for it. I got one for $80 shipped last year and it's been a champ.
