Because all power will be removed from our equipment during this outage, DNS and authentication services will not be available.
If you establish a DSL or dial-up connection during this interval, that connection should remain up but none of our host services will be available, including DNS.
You can browse the web by using alternate public DNS servers. There is a list of free public DNS servers at http://pcsupport.about.com/od/tipstricks/a/free-public-dns-servers.htm.
The above time frame may not be exact but sometime around midnight there will be an outage of all of our servers as power needs to be turned off at the co-location facility to do electrical work to replace a UPS for the facility that has a fried inverter.
They have advised us that it would be best to have our equipment powered down before the proceed to protect it from potential damage so I will be there to do so and bring it back up afterwards.
I was able to get sound working again on Shellx, and fix a nasty problem with pirut, the add/remove software program, but in order to do so I had to remove a bunch of stuff and downgrade others to get versions in sync. I’m still re-installing things but if there is something in particular that you need, please e-mail firstname.lastname@example.org and I’ll bump it up on the priority stack.
We will be taking shellx out of service late Friday evening and returning it to service early Saturday morning. It will be up and down intermittently during this time frame in order to attempt to fix a problem with gstreamer audio so that flash videos and games and other applications that use gstreamer will properly produce sound.
Sound was broken by a kernel upgrade provided by the CentOS team that did not include all of the necessary drivers for gstreamer. We will be rolling the kernel back to a working version or possibly compiling a kernel if we can’t get one supplied by the CentOS team to work.
Shellx is restored to service. X2Go was borked by an upgrade that was supposed to add support for gnome3-fallback and cinnamon sessions, neither of which are desktops available on this server. Given that, I’ve downgraded to the previous working version.
Sound is still borked. Fixing it is going to require downgrading kernel because drivers aren’t available for the current kernel. Since this will most probably require multiple reboots, it’s going to wait until late Friday night.
Sound not reliant on gstreamer works but unfortunately that’s a minority of applications.
Something in shellx pertaining to X-sessions is borked in such a way that X2Go fails to launch a session. I’ve totally reinstalled the X2Go software to no avail.
I am going to take shellx down to recover from a previously working state and then re-apply updates one at a time so I can determine which, if any, of them may have broke the server.
Shellx will be down for approximately one hour.
The UPS at the co-location facility where we have our equipment located has failed. They are working on repairing it. In the meantime, if city power fails in Bellevue, a brief outage will result while equipment is switched to generator.
Maintenance is completed, all services are up.
I will be performing maintenance tonight that will involve a reboot of the main file server to make a new Linux kernel active, and then taking down other machines, specifically shellx, scientific, mail, and ftp, for imaging.
I will not be taking down the other shell servers during this interval, so except for the initial file server reboot, the others will remain functional. The file server reboot will take place between approximately 00:05 – 00:30.
I accidentally installed Kerberos on debian.eskimo.com (which overwrote the Pam configuration files breaking authentication). It will be down for about an hour. If you wish to use a Debian based shell server in the interim, please use either ubuntu.eskimo.com or mint.eskimo.com, both of which are derived from Debian.
