 Posted: Fri Dec 13, 2013 10:39 pm Post subject: ZFS kernel panic after installing new disks - HELP![solved] |
 |
|
Hi all,
I just finished mirroring new disks into my ZFS root (rpoolc). After I changed them both, I ran genkernel to include a new zpool.cache:
| Code: |
genkernel initramfs --no-clean --no-mountboot --zfs --callback="emerge @module-rebuild"
|
I use UEFI stub to boot. So I simply copied the new initramfs into my EFI partition where I keep the kernel and initramfs. When I reobot, I get a message saying that rpoolc is already imported, it can't determine the root device, and that rpoolc/ROOT/gentoo is not a valid file system.
I have tried booting up Ubuntu liveCD as I use the latest ZFS version and Gentoo LiveCD does not support that. I then zpool import rpoolc -R /tmp/mnt, and basically chroot in and try to recreate a new zpool.cache with no luck (this has usually fixed my problem in the past). I am now at a total loss. There has to be a way to fix this - any suggestions?
Oh - genkernel initramfs refuses to give me an option to drop into a rescue shell - otherwise I would just fix this with an export/import of the pool and then continue booting.
Thanks!

Figured out I need to use gnekrnel-next. genkernel has a bug about using /dev/disk/by-id which is how my ZFS mirror is made. I have at least figured out how to manually boot up now.
Thanks ryao, dlan, and prometheanfire! |
