/proc/mount which looks symlinked to /etc/mtab seems to have zfs commands with a "casesensitive" property which is not valid (sensitive|insensitive|mixed). Still trying to figure out how that command is generated.

benwilks commented 6 months ago

Documentation from OpenZFS suggests prop is casesensitivity -- sensitive https://github.com/search?q=repo%3Aopenzfs%2Fzfs+casesensitivity&type=code

but it looks like casesensitive property is used elsewhere too https://github.com/search?q=repo%3Aopenzfs%2Fzfs+casesensitive&type=code

I did bump into this with the Ubuntu HWE kernel. The source seems to be in a dynamically generated systemd file within the initramfs sysroot.mount.d/zfs-enhancement.conf which has an Options= under the [Mount] section. Not sure what makes it become an issue.

I use the ZFS Boot Menu to open a chroot and did a dracut --regenerate-all --force to rebuild the images and reboot which booted up fine after that. Feels like there is a hook missing that should trigger that as I've had to do this again after other kernel updates but haven't been able to track it down. The older 5.x kernels seem fine, just the 6.x kernels was doing this for me.

Thanks for the quick response! I tried running dracut --regenerate-all --force but it looks like it still generates the "dracut: stored kernel commandline:", "dracut: rootfstype=zfs rootflags=rw,noatime,xattr,posixacl,casesensitive" with the problematic casesensitive option that seems to be preventing booting. Any idea how to override that?

Ended up using a 22.04.1 ISO instead which worked smoothly!

Weird. Thanks for letting me know.
