** Description changed: - As reported in bug 1686514, sometimes /mnt will not get mounted when re- - delpoying or stopping-then-starting a Azure vm of L32S. This is - probably a more generic issue, I suspect shown due to the speed of disks - on these systems. + === Begin SRU Template === + [Impact] + There is a race condition on a re-deployment of cloud-init on Azure + where /mnt will not get properly formatted or mounted. This is due to + "dirty" entries in /etc/fstab that cause a device to be busy when + cloud-init goes to format it. This shows itself usually as 'mkfs' + complaining that the device is busy. The cause is that systemd + starts an fsck and collides with cloud-init re-formatting the disk. + + The problem can be seen other places but seemed to be most reproducible + and originally found on Azure. + + [Test Case] + 1.) Launch a Azure vm, ideally size L32S. + 2.) Log in and verify the system properly mounted /mnt. + 3.) Re-deploy the vm through the web ui and try again. + + [Regression Potential] + Worst case scenario, these changes unnecessarily slow down boot and + do not fix the problem. + + [Other Info] + Upstream commit at + https://git.launchpad.net/cloud-init/commit/?id=1f5489c258 + + === End SRU Template === + As reported in bug 1686514, sometimes /mnt will not get mounted when re-delpoying or stopping-then-starting a Azure vm of L32S. This is probably a more generic issue, I suspect shown due to the speed of disks on these systems. + Related bugs: - * bug 1686514: Azure: cloud-init does not handle reformatting GPT partition ephemeral disks + * bug 1686514: Azure: cloud-init does not handle reformatting GPT partition ephemeral disks
