Longest Raspberry Pi uptime

[Thicko_1970]

The Pi, that I bought last Christmas, has been on for 99.9% of the time. I've powered it down a few times, just to swap peripherals and to make backups of the SD card. I use it with RaspBMC, which I like a lot.

Of course Windows 95 had that HILARIOUS bug that meant it would crash at 49.7 days uptime,
http://news.cnet.com/2100-1040-222391.html

I never noticed that problem (I remember resetting the BST/GMT many times too, so it definitely ran for at least a year at a time) - so it probably depended on specific builds of Windows, or whatever services you had running. Mine was just a simple non-networked thing anyway.

The joke when windows 95 came out was "95" meant the number of hours it would run reliably, or maybe even minutes! Not the case for simple applications of course.

Libretto was a great machine, ahead of it's time - but let down by a tiny battery life.

I've been running Debian on some Librettos for years now. They are very reliable (battery life wasn't too bad on my, but I mostly ran them on mains power). Now they are getting a well deserved rest, with some of their functions taken over by the much faster Raspberry Pi

So it is running a year back level on firmware and Linux updates. That could be a security risk.

One of my RPis got rebooted five times yesterday, the other was rebooted four times.

Mine was running my website continuously for just about a year until Thanksgiving weekend when a local power failure took it down. Once the power was restored, it booted right back up and is running fine again.

[jbeale]

This one is physically far away. Still running just fine, and I can login as a normal user but sad to say I've actually lost the root password. I "hardened" it against the attacks I know about, so I can't upgrade or reboot. It may be up for a while yet!

T I "hardened" it against the attacks I know about, so I can't upgrade or reboot.

If you can update /boot/cmdline.txt (either with a windows machine (if it's on the first FAT partition), with the NOOBS recovery system or with another linux system) and add "init=/bin/sh" you can reboot to a root shell (by pulling the power). Once you have a root shell you can update root's password.

You'll lose the massive uptime but you'll be able to bring it up to date.

Mine has been up for a while..

pi@pimachine$ uptime
20:48:10 up 517 days, 2:08, 1 user, load average: 0.23, 0.13, 0.14

[Sisyphus]

Until this evening's power cut, where the Raspberry Pi writes to a file to record the uptime once a day, the last entry says...

07:35:05 up 688 days, 6:24, 0 users, load average: 0.07, 0.22, 0.32

From this, I think I can say the old 256MB early revision Model B I'm using as a server is pretty reliable!

Had to happen one day, now I can look at updating the firmware and changing the micro USB power cable for a better one

[Kratos]

Mine was as follows:

RPi: Model B 256
OS: Raspbian Wheezy
Uptime: 8 days

I was using it normally and it performed well over the entire period.

[dan3008]

I was at 54 days running as a web server, and it was working well...

However, I had a powercut 3 days ago so it restarted....

[ollizei]

Hi everyone,
I found this forum/topic by accident and just wanted to let you know that my Pi is running 569 days now. Why am I doing this? In the past, my Pi never ran more than 14 days due to poor-quality SD cards. After investing a few bucks more for a better SD card, I was wondering how long it would last. My Pi is still running...

Cheers,
Olli

Isn't it the case that on 32 bit platforms, the Linux uptime (being measured in 100ths of a second, aka, "jiffies") wraps around at about 410 days?

So, you could never have more than that of uptime. Or, have they patched this since the last time I tested it?

Note that the Pi *is* a 32 bit platform.

I am not seeing any wraparound bug on my long-term Pi, judging by the last report it sent me...

I don't know what has caused this, but the pcextreme's noc team was kind enough to log in and do a network restart for me saving my precious uptime !

in her 1035 days of uptime it was the very first time she did that

Joe Schmoe,

Isn't it the case that on 32 bit platforms, the Linux uptime (being measured in 100ths of a second, aka, "jiffies") wraps around at about 410 days?

I don't think that has ever been true. Unless there was some horrible bug in Linux at some time that I have never heard of.

Timekeeping on Unix/Linux is based on the number of seconds since the "epoch". 1/1/1970. That seconds counter was due to overflow on January 19th, 2038 at 3:14:08?. Jiffies is a totally other thing.

I'm pretty sure there will be no such rollover on 64 bit systems. I'm not too clear on what is being done for 32 bit machines.

The Raspi Foundation has 22 years left to get that 64 bit Raspbian working!

[DougieLawson]

It's not Raspbian that would need to change. It's Linux and the kernel that provides the boot time & uptime in /proc.

grep -e 'btime' /proc/stat
cat /proc/uptime
