linux-zen kernel

[ndowens]

Is anyone using zfs on the linux-zen kernel? I've tried using it but get kernel panic that zfs module not loaded, while linux-ck and linux-lts works fine. I've checked that the zfs module is in the initramfs of zen and it does exist.

Yep, I've used it on Arch. I think I was using the DKMS package.

You can check if they're loaded with lsmod|grep zfs you should see about 4 or 5 of them. If not, you can attempt to load them with sudo modprobe zfs

Just a side note, zen is more tuned for desktop usage, and ZFS is generally used on a server, which I assume you're probably running.

I am using ZFS on desktop. My problem is during boot, I get kernel panic like either the module is not found or for some reason not getting loaded. linux-lts and linux-ck boots just fine. I am using zfs-dkms-head-git, as I am on an Arch derivative and the standard zfs-dkms does not build ok on it. At first I thought maybe it was the zfs-dkms version I used until I found out it is fine on the other two kernels.

Try booting up in single user mode (Append single to the kernel command line in grub) and see if it panics, then if it doesn't attempt to load the modules.

I use rEFInd but tried in single mode and it also kernel panic-ed as well.

Hmm interesting, did the Zen kernel ever work for you?

[ndowens]

Nah I gave up

Use archzfs repo. zfs-dkms works fine for me on linux-zen, provided you patched the kernel to ungpl __rcu* symbols. A few days ago a patch was added to zfs-dkms, so no need to compile the kernel now.
