| meena | ebal[m]: what's the issue on kernel > 5.7? | 08:52 |
| meena | i'm trying to remember why we made those exceptions for fallocate on XFS rather than just always using dd to begin with | 08:55 |

| meena | why not truncate, i wonder… | 09:14 |
| meena | ebal[m]: that's two minutes?! | 09:15 |
| ebal[m] | test on wsl ;) (work laptop) | 09:18 |
| Odd_Bloke | otubo: Ack, thanks! | 13:06 |
| Odd_Bloke | [42]: Are you using netplan to configure your Debian system, or you were just referring to the configuration format? | 13:09 |
| Odd_Bloke | I would expect cloud-init to accept any valid netplan configuration; if you aren't seeing that then a bug would be much appreciated! | 13:10 |
| Odd_Bloke | ebal[m]: It looks to me from the link to linux-fsdevel on that Bugzilla ticket that you're hitting a kernel bug, not a cloud-init bug; have you raised the issue with your distro's kernel maintainers? | 13:16 |
| rharper | ebal[m]: meena: re: fallocate on ext4 on 5.8 kernels, https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1894910 | 14:23 |
| ubot5 | Ubuntu bug 1894910 in linux (Ubuntu) "fallocate swapfile has holes on 5.8 ext4, causes: swapon failed: Invalid argument" [Undecided,Confirmed] | 14:23 |
| ebal[m] | There is already a couple (or a few) bug reports for this issue (linux/fallocate) and for archlinux also. | 14:26 |
| ebal[m] | Nevertheless, I wanted to openly discuss it here and exchange ideas or even a workaround. | 14:26 |
| ebal[m] | personally I am blocked - but it is not important | 14:27 |
| rharper | dd is the workaround; since this is a regression in the 5.8 kernel, I wouldn't expect any changes to cloud-init here | 14:27 |
| ebal[m] | it is important to see if there is of any value to suggest that cloud-init can switch to dd as a primary choice instead of fallocate or even provide a flag in cloud-init configuration file so you can choose how the swap partition will be created | 14:29 |
| ebal[m] | cause in the end, it is a choice to use fallocate against dd ( I guess ). | 14:29 |
| rharper | I don't see cloud-init switching; it's a regression in the filesystem in the kernel; as a workaround for right now, one could use boothook to run a command to move fallocate out of $PATH (mv /usr/bin/fallocate /root); when cc_mount runs create_swap with fallocate, this will fail, and cloud-init falls back on dd; | 14:34 |
| rharper | ebal[m]: I suppose a PR to allow swap: config to take a command would give the user some control over what to use; | 14:35 |

| [42] | Odd_Bloke: yes also using netplan to configure it | 14:43 |
| Odd_Bloke | [42]: And does the configuration work if you manually apply it? | 14:51 |
| [42] | yes | 14:53 |
| [42] | this is an example for a machine without public ipv4 https://paste.debian.net/plainh/a1eb40cd | 14:55 |
| Odd_Bloke | [42]: Are you able to pastebin cloud-init.log from an affected instance? | 15:02 |
| [42] | i can launch another run in a bit, will need to make sure to set a password to be able to login via console :) | 15:03 |
| Odd_Bloke | :) | 15:03 |
| Odd_Bloke | robjo: Are the Python versions that you care about for SUSE still 2.7/3.4 for 12.4 and 3.6 for 15? (Is cloud-init still(?) being backported to 12.4?) | 15:08 |
| rharper | [42]: thanks for posting, I don't believe your target os supports netplan, I can reproduce the error with your config when rendering from netplan input to eni; | 15:08 |
| rharper | https://paste.ubuntu.com/p/wZYpgq498f/ | 15:08 |
| rharper | [42]: do you have what you expect /etc/network/interfaces should look like? or did you expect netplan to work in which case, netplan detection on debian may need fixing | 15:09 |
| [42] | i did expect netplan to work | 15:09 |
| [42] | i'm already using it with netplan manually on some machines | 15:10 |
| [42] | as in non-cloud-init setups | 15:10 |
| robjo | Odd_Bloke: yes, I am in the process of switching the build for SLES 12 to Python 3.4 | 15:11 |
| [42] | the error in your paste looks like it's exactly what i saw in the console when i tried | 15:11 |
| [42] | netplan rendering from the config above results in https://paste.debian.net/plainh/ed1efb52 | 15:14 |
| rharper | [42]: ok, the boot logs will be helpful: it sounds like you have both ifupdown and netplan installed, cloud-inits default policy for net renderers will try eni first, if found it'll render that; | 15:14 |
| [42] | that could be the case, i'm using a modified debian cloud-init image which i added netplan.io to | 15:15 |
| rharper | if you;'re creating your own image, then you can modify /etc/cloud/cloud.cfg and set network: renderers: ['netplan'] | 15:16 |
| rharper | under system_info: | 15:17 |
| [42] | ok, i'll have a look at that after work, thanks | 15:17 |
| meena | robjo, Odd_Bloke: does cloud-init even work with 3.4?? | 15:51 |
| powersj | during last years cloud-init summit, as we deprecated python 2 support we agreed to start python 3 support with 3.4 | 15:54 |
| robjo | I have a few more package dependencies to resolve but do not expect any issues on 3.4 | 15:55 |
| Odd_Bloke | meena: Yep, 3.4 is our lowest supported version. | 16:19 |
| Odd_Bloke | (Else we'd have much better type annotations. :p) | 16:19 |
| meena | i was wondering… | 17:19 |
| meena | yah, in libioc we went with 3.6 as the lowest bar | 17:19 |
| meena | i think… mostly… cuz that's what the lowest bar in FreeBSD was | 17:20 |
