So you don't > need to set up two separate layers (RAID and filesystem). Hmmm. I'm not planing to use RAID so that could change things. I may use some other OS/software. I'm not real quick to use Gentoo since it likely won't be updated very often. I may research and see what else is easy to install, will do what I want software wise and be OK with not being updated very often. I read once where a guy built a file server/NAS and stuck it in a closet. He used it all the time but just never thought to go to the closet and do anything to it. I think he was moving and was cleaning out the closet and realized how long it had been sitting there untouched. He said it was dusty and had a uptime of over 5 years without a single update either. I may not be that bad but going a year or so is certainly likely. Gentoo will not be happy with that. Just have to wait and see I guess. Dale :-) :-)

AT decided that the other day was as good a time as any to let the DSL go down for a few days. AT made a huge mistake letting the whole community out here sit for days without service. With the new much faster and economical service coming, anyone who might have stayed with AT is now ready to switch. Bad thing is, almost every one out here depends on the internet to watch the weather and we had some storms come through overnight with no way to know what was coming. I just hid under the covers. Way to go AT You got a nice shovel, keep digging. ROFL My router has yellow connectors for routing and a blue connector going to the internet/WAN/whatever. My modem is similar except it is green for the telephone line. If I recall correctly all of those are supposed to be GB connectors, not that the modem could ever do that over the internet but it can between devices hooked to it. I disabled the wi-fi and such on the modem, not enough range anyway. Step away 30 feet or so, no signal. My router also has two USB plugs for sharing external hard drives or USB sticks. I'm not talking about that because I don't like hooking a drive up over USB. It never works well for some reason. According to the link below, I hook the NAS up to the router via ethernet and it is available for all devices connected to the router.

Computer isn't to old but the on board ethernet was flaky last I tried it. I disabled it and used the network card from my old system, which had the same problem of a not so stable on mobo network. It's a 100MB version. I think it is a large B. Since it is a old card, I want to upgrade to a faster one. Until now, I never needed one.

If needed, I can just not use the 2nd port I guess and not enable it until I do need it, if ever. Price isn't to bad. I'm still waiting on a time frame of when the new internet will get here.

IIRC, ZFS uses a licence that is not compatible with the kernel's. That's why ZFS on Linux (ZoL) cannot be integrated into the kernel. Instead, you build an external kernel module (available in portage), which isn't always compatible to the newest kernel out there. > I'm not sure if it uses anything else for file systems either.

Yeah, a pure server should be left alone unless something is broken. My NAS sits in the corner, unused and switched off for many weeks in a row. So when I do switch it on, I usually do an eix-sync right away. > I also wouldn't mind having a media center type box as well. I thought > about buying some sort of used game station type box for a media box. I was flirting with the idea as well. But since I don't have a TV or any good living room speakers at the mo, I just won't have any real use for it right now. My favourite candidate is a ZBox Nano CI329. It is passively cooled and looks nice. It has two ethernet ports, which makes it ideal as a network server and firewall, HDMI for the TV, a 2,5″ internal bay and a hidden mSata slot under the mainboard (to reach it you have to break the warranty seal, b/c the ZBox can be bought as a barebone or as a Windows box, which has its bloatware preinstalled on a small mSata SSD). Its power consumption is very low, rivalling that of a Raspberry. Sadly, they ditched the infrared port which previous generations had. Because they are ideal media players for the living room. -- Grüße | Greetings | Qapla’ Please do not share anything from, with or about me on any social network.

In a way, I have several things going on. My backup drive is getting full, super fast internet is coming soon, I need to upgrade my network card for that plus I want to get something more advanced and expandable for file storage, mostly videos. I also wouldn't mind having a media center type box as well. I thought about buying some sort of used game station type box for a media box. I've heard those can be networked and used to watch videos on TV with and perform pretty well. I also want to get back to work on building a speaker system for my TV as well. I put that on back burner when I got busy with tree cutting and then along comes the bug. At the moment, I'm planning to get a network card. I need that for the faster internet but I'll also need it for the NAS as well. If I can connect that to my router, that alone will help a lot. I can then connect something to the router and access the NAS, even on wi-fi. I like that idea and it appears to be the way it is done. I'll look into them but it mostly depends on what I use for a OS on the NAS. Thanks. Dale :-) :-)

Howdy, Somewhat related. I googled and it appears I can hook a NAS to my router and share it there. The router is 1GB, it has yellow ports. Is it true that I can hook a NAS to the router? I'd assume it can be shared with anything connected to the router, even my cell phone if needed. Also, I'm looking at a new network card for my PC.

For my own personal purposes, I'd never use anything that trust my data to a single hardware component. I've heard stories of raid cards that if they break, you need an identical replacement or the data is kaputt. For that reason I only ever used software RAID which makes me independent of the hardware underneath. > You may want to make note of that for the future. Maybe you can find a > good deal.

I was making suggestions for you, I am not looking myself. ;-) (Although sometimes I wonder whether I should go for a 6-bay system, because I am at around 80 % use of capacity now, and though shalt not go over that on ZFS. But I have loads of DVDs that I can still convert to more efficient compression, giving me back 100s of GB. That's a chore for the upcoming holidays. When I was planning the build, I think I also looked at the Node 304. But it was too big for my taste (I like it small and compact) and had no hot swap. I admit I never had any use for hotswapping yet, but it's nice to have and to see the idividual HDD leds do their stuff. :) > I bought a Cooler Master HAF-932 years ago.

My main PC case was chosen maxed out from the start for what I wanted to do with it: one system SSD, one data HDD, one ODD (mainly to watch and store video DVDs), one HDD hotswap bay (for old and external drives and for backups), space for a not-too-big GPU. It's been running fine for over 6 years now. Only downside: you get either well made cases, or compact cases. It seems both in one case is not available. My case is made from thin sheets, which makes the system louder to my ears than necessary. > Looks pretty good too. I'm not into the LEDs and > all that stuff.

Weighing positives and negatives gets rough. ;-) A bit OT now, going into the backup subject. I don't backup the NAS. People say RAID is not a backup. What they mean is backup from accidental deletion or malware attacks. To me, it is a backup, but from hardware defects. I use RaidZ2 (ZFS-speek for RAID 6), so any two of the four drives may fail without loss of data. But with four drives, this gives me a space efficiency of only 50 %, hence the thought of going 6-bay. The most regular "backup" I do is a unison sync of ~ and some other folders between PC and laptop. It is very fast and allows me to have everything that is important be up-to-date without much effort. But I've never backed up my teensie raspi (remember, it contains my PIM server) or my whole laptop ever since it got an upgrade to a 2 TB SSD. (My PC's data drive is only 1 TB.) Before I built my NAS, my largest drive was an external 3 TB USB drive. It was my main video storage (naturally w/o backup). Since I built the NAS, I've never used it again. So a few weeks ago, I repurposed it as my main backup drive. It's at least 6 years old, but only has ~280 hours on the meter. In the past, I only (semi-regularly) backed up my main PC via rsnapshot to an old 1 TB disk sitting permanently in the swap bay. I've always wanted to try out borg backup. Thanks to that, I now have a backup of my system, home and data partitions of my main PC *and* my laptop, plus the entire raspi. But due to to borg's deduplication magic, the 3 TB drive is only about half filled, even though it contains several weekly snapshots already, amounting to almost 7 TB across hosts. -- Gruß | Greetings | Qapla’ Please do not share anything from, with or about me on any social network.

I am aware of the problem and that we (actually through Dale) had this topic on this list. I built my NAS in 2017, IIRC, and back then there were no EFAX drives around. First I only bought two drives -- from two different retailers in order to minimise risk of batch failure. One year, when space became scarce, I filled the remaining two slots. I'm not really a WD fanboy in any way, but if I bought HDDs (which doesn't happen often to begin with) I always chose WD, because their model lines were easy to grasp through the colour codes. There is a saying in German tech culture: "Entweder sie geht oder sie geht nicht." (either it works or it doesn't).

The board needs to be properly designed, too. I like to leave a lot of extra room when picking the wattage. My current rig draws well under 200 watts and that includes monitor and some other stuff. I figure the rig itself pulls around 100 watts, or maybe a little less, idle. Still, it has something around 600 watts for the power supply. Age gets them but never lost one due to being overloaded. I'm not aware of ever losing a hard drive due to bad power either. I've had them suffer from bit rot tho, platters go bad I guess. I'd rather over do it than under do it. Of course, a 1500 watt power supply for my rig would be way over kill. I tend to aim at around 30 to 40% or so but sometimes because of a good deal or a better unit, I may go a little higher.

The network connection is likely to be the bottleneck. I've read several articles about building a NAS or buying one. That's one point most all of them make. The network is usually going to limit speed not the CPU, hard drive etc. Speaking of, given the upcoming internet upgrade and it's speed, I got to get a new network card for my puter. I currently have a old 100Mb card, I think it is Mb instead of MB. Either way, it's slow and likely to limit my internet speed. Plan to find a GB one. My router is already fast enough.

I don't think that's a good idea. I remember you talking of lousy power utility reliability, and from what I heard over the years of the general standards of US rural power cabling (of course I'm no expert or even just savvy), I'd be worried of interference. I'd also be concerned about damage through physical contact (i.e. you bump into it, or something falls against it). > Of course, another option is to make this a media system and use those > little raspberry type thingys for the NFS. I am running raspi as a low-level server (pi-hole, Nextcloud, contacts and calendar server). It's a model 3B with a quadcore SoC and 1 Gig of ram, currently running raspbian (I am currently examining arch). For what you want, it is not powerful enough. Even the gen 4 does not suffice. It has gigabit ethernet (the 3 only has 100 Mb), but has no SATA connectors. So you either need a SATA bridge or are limited to USB enclosures. It has two USB-3-Sockets. Either way, you need a separate power supply for 3,5″ drives. On [0], the Pi 4 is benchmarked and reaches 363 Mb/s over USB. That is a third of Gigabit speed. Not counting overhead for filesystems. > Or, buy a used NFS off ebay, kinda pricey last I looked. I built a NAS in a for-purpose cubic case [1] a few years ago. The system was costly, maybe even unnecessarily high, because I went with a niche Mini-ITX form factor, ZFS (for redundancy), thus ECC RAM, thus a server board that supports ECC. On the other hand, that board supports staggerd spin-up. At idle that system slurps around 50 Watts with a 300 W gold PSU. It has four WD RED 6 TB drives and a small SSD for the system. It is actually the last Gentoo system that I run and maintain. :'-( System upgrades puts some heat stress on the drives because they sit right atop the CPU due to the crammed dimensions, but since it's a server, the package count is hugely reduced compared to a desktop. And since I don't keep it running 24/7, I usually do upgrades right after bootup. My case is quite cheaply-made, with sharp edges here and there and some design flaws. An adequate,

I quite often find myself googling for examples of something. Once I look at examples, hopefully with some nice comments, then I can usually figure how to make something work like I want, even if it is different from the examples. Sadly, I couldn't get that with some video players recently. I literally copy and pasted the config and the mouse doesn't control anything. I'm not sure what to make of that. :/ At least the keyboard keys work. I do use LABELS so I'm good there. Most everything is in LVM but / and /boot is not. You know me and the init thingys. Bad enough to deal with what I got. lol On the other topic. I found this. https://www.fractal-design.com/products/cases/node/node-804/black/ I found them on Ebay, brand new even, at around $100. That thing is NIFTY. Lots of hard drives and doesn't cost a arm and a leg, plus maybe a head as well. Some of those cases get expensive quick and hold a lot fewer drives. Still like the raspberry type thingys power wise tho. It would need a really good power supply tho. Thanks. Dale :-) :_)

Well, I feel as frustrated as you with my new setup. My new mobo
wouldn't boot so I took it to the shop saying "I think it needs a BIOS
update". They replaced the mobo, and fortunately offered me the old one
back before chucking it. I discovered it was still under warranty, sent
it back to Gigabyte, and it came back fixed with a BIOS update!!!
The replacement mobo (which they charged me twice what I'd paid for the
original) was spec'd as having "plenty of onboard SATA". I think the old
Gigabyte mobo had at least 6. The new one has 6, of which two collide
with the graphics cards or NVMe. Seeing as I'm planning on running
multi-seat, I need two graphics cards ... :-(

I ran that same Matrox - loved it - with an Athlon 1400 - tbird - and
that lasted me ages and ages. The chip ran at 1050 because the mobo was
a 100MHz bus but the chip wanted 133MHz. I think that machine had 758MB
ram - 3x256MB sticks because that's the max it would take. And because
its replacement had "issues" (still does) I compiled everything on the
slow machine before installing it on the fast one ...

I already got one. Yes, I'd pitch MoBo w/many SATA vs. MoBo w/fewer
SATA plus AddIn, but PCI(e) slots are also limited and >=2 port cards
get expensive rather quick, say a card with >= 4 internal and
_extra_[0] 1-2 eSATA ... So, I'll rather have a MoBo with lots of SATA
+ addin than MoBo plus tons of addin cards...
My MoBo has the AMD 710 "Southbridge" with 6 int. SATA2/3G [1] ports,
a MV9128 with 2 int. SATA3/6G ports and a JMB362 with 2 ext. eSATA2/3G
ports. Try to find _anything_ even remotely resembling that (with any
SATA rev) ;) My guess is, with most MoBos you'd need two 4-port addin
cards even for that. And my MoBo was not even expensive, just ~80 EUR
in 04/2010. BTW: GA-770TA-UD3, hosting a AMD Athlon II X2 250 for then
~65 EUR :) Still running as champs :))
Again: find me a MoBo + Addin Card(s) Combo with: >= 9 internal SATA
ports, >=1 eSATA ports (dedicated, not switched with one of the
internal ones!). An IDE port would be a nice extra.
Were it not for gentoo and large stuff needing 6+ hours to compile,

It sounds like a good idea since right now, I could move those drives to a system that has the same names which would cause issues.

That's something to keep in mind. I know start up is when drives put a load on a power supply. I might add, right at the time the power supply is trying to get its stuff in gear. For my main system, I think I have a 600 watt, maybe 650. I've got several drives in it tho. According to the UPS, it only has a 190 watt load and that includes the puter, monitor and some other odds and ends. Still, at start up, that power supply needs to be able to handle that surge and at the worst time it can have it at that. A 300 watt power supply with that number of drives could lead to problems if it would boot at all. >> I'm thinking of making a storage system out of it. I think it is >> referred to as a NFS. > Nope. NFS is "Network File System". You mean "NAS" = "Network Attached > Storage" ;) I thought that wasn't right. Later on, I figured it out. It was just one letter but it was a big difference. :/ >> It should be plenty fast enough to move data around.

That's one reason I was thinking about those Raspberry thingys. I've read some of the new ones have more features and more processing power. Keep in mind, I'll only be playing videos from it or saving videos to it or making backups. Of course, with the upcoming fiber connected internet, saving videos can take up some bandwidth. It's rated at 200MBs/sec. I doubt it will be quite that speed but still, SATA isn't that fast either. ;-) One thing, I want to be able to expand which is why I want to build instead of buy. The recent Dell is a start at least. >> I see only two spaces for hard drives with one already taken. There >> is a open area that I could add a drive cage, I think.

Hi, I think the system is enough for a basic NFS. The CPU support x64 and 8Gib memory is enough. The graph card is ATI Radeon HD3200 seems support UVD hardware decode for 1080p h264 video, a little poor for a media system. But the cpu power is 125W, will cost much electricity for a 24h home system. Using a raspberry-pi may save power, but come with poor performance, also it is said that the new raspberry-pi-4 has a decent performance. If you want to get a good NFS, please pay high attention to the power supply, it is very important for hard disks. Power fluctuation may destroy your disk. That is also raspberry's weakness, it generally can't provide a stable power for the disks. I am not very familiar with LVM, let other people answer the question. But I also recommend that you can have a look about "btrfs" and "zfs". Best regards. -- bobwxc OpenPGP_signature Description: OpenPGP digital signature

Of course, that means I have to add card(s) for the controller(s). It doesn't have a lot of expansion slots but may be enough. Mobo is only SATA. Another option, find another case. If I recall correctly tho, some puter makers don't use standard layouts for the mobo screw holes. Anyone know if Dell is a standard ATX or some other screw hole pattern? I could also have a open system with everything just mounted on the wall in open air. Would help a lot with cooling for sure. It does open it up for something hitting it directly tho. I don't really like that idea but it's a option. Of course, another option is to make this a media system and use those little raspberry type thingys for the NFS. Or, buy a used NFS off ebay, kinda pricey last I looked. Either of those would likely pull less power. I'm sure the little raspberry thingy would pull very little power. One may need to worry about what the drives pull more than the raspberry thingy itself. Heck, even fans can add up. I have another question related to LVM. Let's say a system crashes and dies. Or I just move a drive, or drives, with LVM on it to another system. Does the system just recognize the drives and knows how to add them or do I have to do that manually on the new system? I've googled in the past but never quite got how that works. I've read it is doable but not sure how. Would a small raspberry thingy be better in the long run from a light bill point of view? Can I use SAS drives with it? Keep in mind, I plan it to run 24/7. My TV is almost always on, if I'm home which is a LOT since I'm disabled. Some of this is me thinking out loud. Some is trying to look for ideas, opinions etc. Of course, I got questions up there as well. Link to pics. I hope it works. There isn't really a good image hosting site I can find. All of them limit something or other. One pic is a side view of system, one shows the open space a drive cage may can fit into, hard to see tho, and another is of the cage itself. It's the only cage I have but ebay has them too. https://freeimage.host/a/dell-546.dBilt What will I get into next? May be back in the woods cutting trees again before to long, health and weather allowing. Always something but the puter is a somewhat nice something. ;-) Dale :-) :-) P. S. They said they replaced it because it was getting slow. During my inspection, I noticed the CPU cooler needed cleaning. It was about stopped up with dust. The rest of the system tho is clean. We all know how those CPU coolers are dust magnets, video cards too. It looks like they would make them so they wouldn't plug up with dust but I guess if they could, they would have by now. I blew out the dust with my portable air tank and it runs much faster than it did the first time I booted it. I rescued some pictures off of it for them. I opened LOo as a test. It took a while the first time. After cleaning, opened up in just a few seconds. Much faster. Sometimes I like getting a dusty rig. ROFL
