It should be possible. I have a Pi in a data center that recently passed the 2-year uptime mark. However it is not doing much, just remote archive of some files every day, plus running asteroids@home to while away the time, and it sends me an email with the uptime once a day.septantrionalis wrote:Honestly, I would love more stability as a server. I used to have one server that ran everything and would get uptimes in the years. The longest uptime was almost 5 years. I've replaced that aging system with various Raspberry Pis. One pi runs my blog, another pi runs my file server, another pi runs my mail server, etc, etc. I am finding that the servers have to be restarted at least once a month. The software either crashes, or the pi just spontaneously turns off, etc. I'd love to just fire these devices up and forget about them.

Are you sure that the power you are giving them is sufficient? Or perhaps there's some sort of software bug. I have three pi that are just left running most of the time and I can't remember there being a problem with that. They are not overclocked.septantrionalis wrote: I am finding that the servers have to be restarted at least once a month.

I have a total of 10 pi's that do various tasks (web cams, specific web services, load balancer, etc) and I've tried different power suppliers, different SD cards, different configurations, etc. Nothing works. Honestly, I shouldn't have to go through these lengths to get it to work so that's why I mentioned stability.stderr wrote:Are you sure that the power you are giving them is sufficient?

If a Pi had that the sales would be huge.fruit-uk wrote:I want one that will pick guaranteed winning lottery numbers

I would check the gauge of the cables providing 5v power to your Pii, although if you're using an Adafruit supply meant for a Pi, that should be good enough. You can't have a large enough gauge power cable, especially as length increases. Next, I would put an UPS with surge protection between the Pi and the AC/mains to filter out spikes, brownouts, etc. (you would not believe what some utilities put out nowadays). Here is the MoPower UPS hat I'm beta testing: viewtopic.php?f=45&t=127700. However, it's a kit that requires some fiddly surface-mount soldering of Really Tiny Parts, but nothing critical, just resistors and LEDs. Everything else is through-board wire leads or power regulators, an inductor, etc., with relatively large surface-mount solder pad areas.septantrionalis wrote:Honestly, I would love more stability as a server.
Well, there's one potential problem, Wordcrash. Seriously, you can have all sorts of problems if it isn't configured 1000% correctly, especially if it's handling a lot of traffic. Just ask the Foundation how they've had to pay an inordinate amount of attention to tuning for everyday activity, let alone when they keep tossing things like $5.00 computers out into the world and then are puzzled as to why they get suicide notes from Mythic Beasts, their hosting service Of course, this doesn't explain crashes on other Pii if they're not running that stack, so if more than one Pi is going Tango-Uniform around the same time, you almost certainly have a power problem of some sort. Looks like you're running a heartbeat monitor, so you should have that data.septantrionalis wrote:Here's the uptime report for my blog server, which is the worst.

Yeah...they might sell--oh, I don't know--7 or 8 million of them. Oh, wait...Heater wrote:If a Pi had that the sales would be huge.fruit-uk wrote:I want one that will pick guaranteed winning lottery numbers
Everyone would be disappointed though, everyone would win, the payout would be worthless.
I wouldn't go *that* far...I recall dealing with #0000 stranded, and that was just ONE conductor.Jim Manley wrote:You can't have a large enough gauge power cable, especially as length increases.
Once I get my hands on a particular board linked to by a poster in another thread (UPS says it should arrive by Wednesday) and get a chance to examine and test it, there may be at least a partial solution. Western Digital makes a CM board that supports a SATA connection. If it has all the other features I want (I can't tell from the web page if it has an Ethernet connection), then the release of a CM2 would make it a really nice member of the Pi "family".rurwin wrote:Some of the project I'd like to do with the Pi require a good HD throughput and a good Ethernet throughput at the same time. For example a NAS. That could be cured by providing a USB3 interface, which would be fast enough to handle both simultaneously. But the USB is in the SoC, so it would mean a new SoC and new drivers, and those were a pain the first time around.
Having a shutdown input and a power-off output would be useful for the people who want to embed a Pi in a car or whatever.
The SoC range used in the Pi only has a single USB channel in to the device, so throughput will always be an issue until a different range of SoC is selected. At which point, almost all the work done on optimising Raspbian and apps goes out of the window(new architecture, new GPU, new camera I/F, new DSI I/F, new GPIO system etc). So it's more than a $20 upgrade. It's definitely a limitation, but currently one with no sensible solution.rhubarb65 wrote:My Pis have been pretty reliable, (Samba server,VPN gateway and more)
the main issues for me with the PI2 are
1 desktop performance. Web Surfing still not useable. Needs 50-100% more CPU and a couple more GBs RAM.
2 server performance. IO throughput too slow (2.5MB/s). Lose The USB - NIC hardware contention to hopefully double throughput.
None of this need cost much 10-20$ ? and we now have a low-end but useable desktop or server. This is the PI3 hopefully. There is SOOOO MUCH demand
USB3 and another CPU doubling in the PI4 and we have a sweet mid range
and yes I know this is not what the original Pi was about (Kids experimenting). But it is what the new Pis will become
Dont forget that the Kids need a desktop to find the info they need in order to experiment
