zfs module won't load after centos kernel upgrade

Post by kenjakt » 2017/06/20 19:56:26

Hello,

I updated my centos 6.8 to 6.9 which updated the kernel from 2.6.32-642 to 2.6.32-696, but the zfs installation hasn't kept up with this change in kernel and refuses to load now. The error I get when I try to run any zfs command like zpool status is,

Failed to load ZFS module stack.
Load the module manually by running 'insmod <location>/zfs.ko' as root.

Is there a way to fix this preferably without data loss?

Thank you
Krishna

You should probably ask the people you got the ZFS from.

You almost certainly need to rebuild (reinstall?) zfs after every kernel update.
The future appears to be RHEL or Debian. I think I'm going Debian.

CentOS 5 and 6 are deadest, do not use them.
