uh-oh…

Thanks for the post though, Progress looking great!
Mostly bug fixes, like not using a hotspare (data) to replace a special vdev provider?..

Thanks for the heads-up.

Now I need to watch the auto upgrade on all my Fedora boxes because of zfs’ broken dkms integration.

Background

Every time zfs gets updated dkms breaks (dkms status returns an error) and needs manual fixing.

  • Because dkms is broken by the installation of the updated zfs packages, the dkms doesn’t compile the zfs kernel module for the current kernel. Therefore, all zpools are gone after the upgrade.
  • If the dnf update also pulls in a new kernel version at the same time you get a double whammy: Because the kernel module compilation fails, no initramfs is generated for the new kernel version which leads to the computer not booting and a cryptic and scary “kernel panic” :frowning:

Solution:

  • boot into an older kernel version, which has an existing older zfs kernel module.
  • In the dkms folder for zfs (/var/lib/dkms/zfs) you will find two folders named after zfs versions. The current version and the old, no longer existing, zfs version. rm -rf that old folder and the now broken links into the old folder. → dkms status now works without error.
  • Sometimes dkms status shows latest version of zfs registered with dkms, sometimes not (not sure why).
  • To register: dkms add zfs/2.1.7 or whatever the version of the installed zfs is.
  • dkms autoinstall to build kernel modules for the current kernel version; dkms build -k $(uname -r); dkms install -k $(uname -r); does the same for the current kernel version.
  • replace kernel version for other installed kernel versions - especially the latest installed version.
  • Create a new initramfs for all the kernel versions that need it: e.g. dracut -kver $(uname -r) for the current kernel version. Verify with ls /boot/ that initramfs for all kernels exist and have been updated. Reboot. Go on with your merry lifes.

I opened issues with openzfs a couple of times and explained it, but because zfs upgrades happen so infrequently I think this is just not properly tested.
