description |
In the larger G-Series VM sizes (G4 and G5) we have SSD-backed ephemeral disks that are larger than 2TB, and so they look a little different; namely they now use a GPT partition table and they also have two partitions:
------------------------------------------------------------------
Model: Msft Virtual Disk (scsi)
Disk /dev/sdb: 6597GB
Sector size (logical/physical): 512B/512B Partition Table: gpt Disk
Flags:
Number Start End Size File system Name Flags
1 17.4kB 134MB 134MB Microsoft reserved partition msftres
2 135MB 6597GB 6597GB ntfs Basic data partition
------------------------------------------------------------------ |
[IMPACT] Ephemeral storage on Microsoft Azure G4 and G5 instance types use GPT partition tables by default. Cloud-init is not preparing the ephemeral devices.
[FIX] Add GPT partition support to Cloud-init.
[VERIFICATION]
New image:
1. Build image from -proposed
2. Boot G4 and G5 instance
3. Confirm that /mnt is mount as ext4 filesystem
Follow verification steps from Bug #1292648 (comment 3).
[RISK] This is a mild to medium risk change. However the changes are mitigated in the fact that on Azure, ephemeral devices are extra-ordinarily ephemeral; each boot may result in a new ephemeral device being present. Azure users are advised to not rely on the ephemeral storage at all (see Bug #1382257).
