description |
On Windows Azure, the ephemeral disk should be treated as ephemeral per boot, not per instance.
Microsoft has informed us that under the following conditions an ephemeral disk may disappear:
1. The user resizes the instance
2. A fault causes the instance to move from one physical host to another
3. A machine is shutdown and then started again
Essentially, on Azure, the ephemeral disk is extremely ephemeral. Users who hit any of the above situations are discovering that /mnt is mount with their default NTFS file system.
ProblemType: Bug
DistroRelease: Ubuntu 14.04
Package: cloud-init 0.7.5~bzr964-0ubuntu1 [modified: usr/lib/python2.7/dist-packages/cloudinit/config/cc_disk_setup.py usr/lib/python2.7/dist-packages/cloudinit/config/cc_final_message.py usr/lib/python2.7/dist-packages/cloudinit/config/cc_seed_random.py usr/lib/python2.7/dist-packages/cloudinit/sources/DataSourceAzure.py usr/lib/python2.7/dist-packages/cloudinit/sources/DataSourceCloudSigma.py usr/lib/python2.7/dist-packages/cloudinit/sources/DataSourceSmartOS.py]

SRU Justification
[IMPACT] Users on Windows Azure are guaranteed to have the ephemeral device as ext4 for the first boot. Subsequent boots may result in fuse mounted NTFS file system.
[TEST CASE]
Defined in comment 3.
[Regression Potential] Low. This change is scope only to the Windows Azure datasource and the behavior complies with expected behavior of Windows Azure: the ephemeral disk is not durable between boots. From Microsoft documentation:
> Because data on a resource disk may not be durable across reboots, it is often used by
> applications and processes running in the virtual machine for transient and temporary
> storage of data. It is also used to store page or swap files for the operating system.
(See http://www.windowsazure.com/en-us/documentation/articles/storage-windows-attach-disk/)
Even so, the change to Cloud-init is scope to only replace the ephemeral disk when the disk is 1) NTFS; 2) has a label of "Temporary Storage"; and 3) has no files on it. When the disk matches, cloud-init will turn the code paths for formating the ephemeral disk for that boot only.
[ORIGINAL REPORT]
