Invalid parameter 'zfs_arc_max'

[Vasilij Lebedinskij]

hello. I have updated my promos node yesterday . This morning I found it offline, when I arrived at site there was an error on the screen that said I had an invalid symbols in zfs_arc_max value. All I have now is busybox /bin/sh. I tried to remove file /etc/modprobe.d/zfs.conf and edit it from here but after reboot I had same error and this file was at it's place as before and with same content. Where can I disable this parameter or how can I remove this file so that pros mix could use default options

if you are unable to edit it from the rescue shell or continue the normal boot, boot a livecd with ZFS support and

1. import the pool
2. mount /
3. edit or remove the broken file
4. chroot into the root filesystem after setting up appropriate (bind) mounts (e.g. for dev, proc, sys)
5. run "update-initramfs -u" inside the chroot
6. unmount everything
7. export the pool again

and reboot. the /etc/modprobe.d/.. files are contained in the initramfs (because modules might already get loaded there for early boot support), so you need to regenerate it after changing the file.

Thank you! I was able to boot most old kernel and fix initramfs.
