I'm getting a kernel panic on import. I've tried running it in debug and then force mounting in read only. The kernel locks up and I have to reboot.
I've moved the drives to a new machine to make sure there were no hardware issues.
I was trying with ubuntu and zfs
in dmesg:
Looking online, someone has had success doing this: https://github.com/zfsonlinux/zfs/issues/6414
I'm not sure what else to try. It just stopped working one day and kernel panicked.
The freenas 11 machine is quite capable 16gb ram 4 core i7
The Ubuntu box is 32gb ram 8 core i7
Any advice would be appreciated.
