description |
Ubuntu 14.04.3 (20150805) on Azure with cloud-init package 0.7.5-0ubuntu1.8.
On Azure cloud-init prepares the ephemeral device as ext4 for the first boot. However, if the VM is ever moved to another Host for any reason, then a new ephemeral disk might be provided to the VM. This ephemeral disk is NTFS formatted, so for subsequent reboots cloud-init must detect and reformat the new disk as ext4. However, with cloud-init 0.7.5-0ubuntu1.8 subsequent boots may result in fuse mounted NTFS file system.
This issue occurred in earlier versions of cloud-init, but was fixed with bug 1292648 (https://bugs.launchpad.net/ubuntu/+source/cloud-init/+bug/1292648). So this appears to be a regression.
Repro:
- Create an Ubuntu 14.04.3 VM on Azure
- Resize the VM to a larger size (this typically moves the VM)
- Log in and run 'blkid' to show an ntfs formatted ephemeral disk:
# blkid
/dev/sdb1: LABEL="Temporary Storage" UUID="A43C43DD3C43A95E" TYPE="ntfs"
Expected results:
- After resizing the ephemeral disk should be formatted as ext4. |
[Impact]
Sometimes when rebooting an instance in Azure, a different ephemeral disk will be presented. Azure ephemeral disks are presented as NTFS disks, but we reformat them to ext4. With the last cloud-init upload, we shifted to using /dev/disk symlinks to mount these disks (in case they are not presented as the same physical device). Unfortunately, the code that determines if we have a new ephemeral disk was not updated to handle symlinks, so never detects a new disk.
[Test Case]
1) Boot an Azure instance and install the new cloud-init.
2) Change the size of the instance using the Azure web interface (as this near-guarantees that the ephemeral disk will be replaced with a new one). This will reboot the instance.
3) Once the instance is rebooted, SSH in and confirm that:
a) An ext4 ephemeral disk is mounted at /mnt, and
b) cloud-init.log indicates that a fabric formatted ephemeral disk was found on this boot.
[Regression Potential]
Limited; two LOCs change, to dereference symlinks instead of using paths verbatim.
