Azure data source should auto-detect ephemeral disk location |
[SRU] Azure data source should auto-detect ephemeral disk location |
|
| 2015-08-14 15:01:12 |
Dan Watkins |
description |
Currently we assume it will be /dev/sdb, but this may change. There is an example of how to handle this in the Azure Linux agent.
To quote stevez in a comment on bug 1410835:
Device names are not persistent in Linux and could change, so it is not guaranteed that the ephemeral disk will be called /dev/sdb. Ideally this should be auto-detected in cloud-init at runtime (for example, see DeviceForIdePort() in the Azure Linux agent). |
[Impact]
The Azure ephemeral disk will not necessarily remain at the same /dev/sd* location between reboots. This means the drive may not be persistently mounted between reboots.
[Test Case]
1) Boot an Azure instance with a cloud-init including this fix.
2) Ensure that the ephemeral disk is mounted at /mnt and formatted as ext4
3) Ensure that /etc/fstab refers to a /dev/disk/... symlink, rather than a /dev/sd* device.
[Regression Potential]
We now use a udev rule to discover the location of the disk; we have been assured by Microsoft that this rule will always work, so regression potential is minimal.
[Original Report]
Currently we assume it will be /dev/sdb, but this may change. There is an example of how to handle this in the Azure Linux agent.
