I'm trying to install ZFS on a 17.10 install on my Lenovo laptop and the zfs module is not loading. I suspect this may be because I'm using a different kernel to resolve the corrupted BIOS issue I encountered earlier. Here is a scrape of the relevant commands:

Use 'apt autoremove' to remove them.

Should I switch back to a mainstream kernel? File a bug report against the special kernel? Add modules to the kernel I'm running?

I'd appreciate suggestions on the best course of action (as well as pointers instructions for doing this properly.)

Thanks!

Edit.0: I booted Debian Stretch on this laptop and performed the same steps. I noted that the install of the ZFS utilities included 'zfs-dkms' which was not a dependency on Ubuntu. I then booted Ubuntu and attempted to install this package. The process reported some errors and then hung. The scrape from the terminal window is

hbarta@kigelia:~$ sudo apt install zfs-dkms

  • I can't help you in detail. Maybe DKMS may need some configuration: help.ubuntu.com/community/DKMS – davidbaumann Mar 5 '18 at 14:56
  • Hi davidbaumann - thanks for the tip. I looked at the link and don't care to dig that deep into DKMS. I added some information to my post. At this point I'm more interested in proceeding with ZFS related testing than spending a lot of time debugging this problem. Thanks! – HankB Mar 5 '18 at 15:09
