All the GCE bots were terminated over the weekend. Bots affected: - commit-queue - cr-linux-ews/chromium-ews - cr-linux-debug-ews - style-queue - feeder-queue - sheriffbot The problem is the image we were using (ubuntu-10-04-v20120621) was obsoleted. CE recommends using gcel-10-04-v20130104 instead. The hard coded /dev/vdb no longer exists, we should be using /dev/ephemeral-disk-0 to access the ephemeral disk.
A partition on /dev/ephemeral-disk-0 is created as /dev/ephemeral-disk-0-part1. These are soft links to /dev/sdb and /dev/sdb1 respectively. The soft links are not always created in time for the script to use them and it fails to create a fs or mount it. This happened in 12/15 cases. With this is mind it is better to use /dev/sdb and /dev/sdb1 directly. If the image changes again in future this will be a thing to lookout for in case it differs again. Another difference on this image is that /etc/hosts doesn't have general read access thus things are unable to connect to localhost. This breaks the DRT tests. Will need to "sudo chmod 644 /etc/hosts" as part of the VM build.

Haha, I too am perplexed that it needed this. It was 640 by default meaning you couldn't ping localhost!

It was 640 by default meaning you couldn't ping localhost! !? That sounds like a config error in the default image? I wonder if it warrants a GCE bug.
