Uptime

Uptime Collection

This post serves as a collection of our notable uptimes – for several things:

  • Physical servers
  • VMs / Virtual Servers
  • Application platforms that keep uptimes, such as Zope

We will also be posting notable uptimes as comments to the post so that you can get an idea of how we do things.

Good Example [Updated! March 18, 2010]

Here’s one of our primary webservers, running Debian, installed in 2005 prior to our adopting Virtualization across the board in our product line:

webserver:~# uptime
16:26:01 up 1534 days, 10 min,  7 users,  load average: 0.16, 0.32, 1.04
webserver:~# date
Thu Mar 18 16:26:11 PDT 2010
webserver:~#

Yes, that’s right – 4.2+ years.

One of our Physical VM hosts

Here’s our current uptime, just prior to our kernel upgrade which will force a reboot:

root@librehost-h64:~/libre# uptime
17:27:36 up 96 days, 18:36,  4 users,  load average: 0.16, 0.26, 0.27
root@librehost-h64:~/libre#

After this upgrade we’ll be on production/release post-SSH-key Ubuntu Hardy 8.04 LTS.

    Update July 4, 2008 (Happy 4th!):

    OK, we’re about to go live on a new kernel on one of our primary hosting servers – here’s the current one:

    root@librehost-h64:~# uname -a
    Linux librehost-h64 2.6.24-5-server #1 SMP Thu Jan 24 19:58:47 UTC 2008 x86_64 GNU/Linux
    root@librehost-h64:~#

    And we’re about to go to 2.6.24-19-server – here’s our current uptime before the reboot:

    root@librehost-h64:~# uptime
    12:58:19 up 32 days, 17:52, 5 users, load average: 0.40, 0.36, 0.29

    OK time to upgrade the eRacks dev server, it’s been up for 6+ months:

    root@django-11-x86:~# uptime
    21:33:45 up 183 days, 1:28, 2 users, load average: 0.00, 0.00, 0.00
    root@django-11-x86:~#

    So let’s go:

    apt-get dist-upgrade

    Reading package lists... Done
    Building dependency tree
    Reading state information... Done
    Calculating upgrade... Done
    The following NEW packages will be installed:

    The following packages will be upgraded:

    After this operation, 30.6MB of additional disk space will be used.
    Do you want to continue [Y/n]?

    Go, baby!

    So now, after a reboot, it’s just:

    apt-get install update-manager-core
    sudo do-release-upgrade

    And after about 10 minutes, and one more reboot, it’s DONE.
