When attempting to use curtin to install Ubuntu with a BTRFS + luks root, curtin uses an invalid sector size, causing mkfs.btrfs to exit with error 1. It appears that mkfs.btrfs is expecting either a value of 4k or 64k, but curtin generates a sector size of 2048 (from blockdev_sector_size it appears).
In the Ubuntu installer, specifying extra_options directly, worksaround this issue. For example:
- id: boot-format
type: format
fstype: btrfs
volume: boot-partition
extra_options:
- --sectorsize
- 4k
This workaround was lucky, since the cli ignore previous options in favor of later options in the command.
What's odd is that I was was able to successful install using this configuration onto another server a year ago, without needing a workaround - so I suspect a regression somewhere, somewhat recently. |
