NVME block-device-mapping symlinks are not created reliably about amazon-ec2-utils

[nmeyerhans]

Yes, that's correct. 1.2-46 is the one that introduced the problem. I've updated the earlier comment to correct that.

When will the fix hit AL2? This broke a lot of scripts for us as running pvcreate on the device symlink would cause it to disappear.

[nmeyerhans]

Hi @lkinley-rythmos Sorry for the inconvenience. I don't have specific ETA for the AL2 update. For the moment, I recommend either staying on version 1.2-46 1.2-45 of the package or pulling in the fixed 70-ec2-nvme-devices.rules from #23

[tyrken]

Hopefully you can get this update out soon - it broke a lot of our bootstrap scripts also.

FWIW in my testing I found 1.2-46.amzn2 the release that lost the nvme symlinks on formatting of attached EBS disks, our AMIs including 1.2-45.amzn2 were the ones to stick with as still working...

@nmeyerhans can you clarify this?

staying on version 1.2-46 of the package

It's my understanding from internal discussions that we should stay on 1.2-45, not 46. (i.e. this problem was introduced in 46). Is that correct?

[nmeyerhans]

The 1.2-47.amzn2 packages are starting to show up in the Amazon Linux 2 repositories now:

There may be some delay before it reaches every region, so please be patient if it's not available yet where you're running.

@nmeyerhans, I see you're also the maintainer of the Debian/Ubuntu package (amazon-ec2-utils). I'm currently running into this issue on Ubuntu 22.04, which still ships 1.4 (w/o the fix). Any chance to get the Ubuntu package for 22.04 updated to 1.4.1 (in the near future)?

[nmeyerhans]

@dhs-rec I've uploaded 2.0.1 to Debian. I'm not at all involved in Ubuntu and have no idea what it takes to get it updated there.

[dhs-rec]

@nmeyerhans, thanks a lot. Maybe I need to open a ticket for Ubuntu, then...
