Arch Linux User Repository

Tired of compiling? Use this binary repo instead! Add this at the end of /etc/pacman.conf :

[packages]
Server = http://nhameh.ovh/$repo/$arch
SigLevel = Optional TrustAll

Please add dkms to depends.

thanks for this :)

Hello guys, I have adopted this package to make it work with the latest kernel. For my environment it seems to work now, I can get started.

But I cannot guarantee it will work for other environments aswell. If it proves too much work then ill probably end up orphaning these vdo packages aswel. Its just that ... I got it working for me and I just wanted to share my work.

8.x is not production ready. vdo python tool do not exists anymore, there is no easy way to convert existing non-lvm devices to vdo-lvm devices, documentation is not complete [1].

I managed to compile it with 5.15 using https://github.com/rhawalsh/kvdo, but I reverted back to 5.4 kernel from kernel-lts unofficial repo and the latest kvdo 6.x

Hmmm, i see. Since i do not use vdo/kvdo anymore, is anybody interested to take over maintenance for the PKGBUILDs?

Unfortunately no. :) The source now point to a git branch and not to a tagged commit. Since there were new commits pushed in February the SHA has does not match anymore.

The following patch makes it explicit that git branch is used to avoid confusion. Optionally appending string "-git" to VERSION or something like that may be be a good idea too.

Switched to COPR repo, so everyone should be happy ;)

According to README.md on upstream[1], a fork compatible with new kernel versions has been made and is being maintained here[2] under the -COPR branches. While it still requires a patch for config_hz (to remove the check for an integer number of millseconds in every tick), it no longer needs vla-warning, and can compile on latest kernels.

I suggest using this, and have made an alternate version of this PKGBUILD using those sources that works on 5.9.

I made a patch[1] to this repo to get it building again on the latest kernels.
