Upgrade Kernel 4.17: ZFS: Unable to set "noop" scheduler for /dev/sdd1 (sdd): 256

Hi, did you recognize any problems with zfs after a week of using kernel 4.17?

Regards Hoppel

I am trying to install the zfs plugin on a fresh install upgraded to 4.17, but getting following error, did you run into this as well?

.....that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
openmediavault-zfs : Depends: linux-headers-amd64 but it is not going to be installed or
pve-headers but it is not installable
E: Unable to correct problems, you have held broken packages.

i remember there was this header issue with older kernel, is that still the case for 4.17 i was really hoping that was solved

Don't know if I'm to late to add to this but I'm getting the same error. I'm kind of new to ZFS and can't figure out if this is a real problem or not. I'm also on the 4.17 Kernel.

Hi,

I am also using kernel 4.17 and also see this message, but can’t see any errors. So, for the moment it’s not really an issue.

As an alternative you can try the latest backports kernel 4.18. My Server informed me yesterday, that 4.18 is available now. Maybe it’s solved with kernel 4.18 and zfs 0.7.11...

Or you can install the proxmox 4.15 kernel. I think the message isn’t appearing with this kernel, but I also didn’t try.

Please report back your findings here.

Hi,

today I updated to kernel 4.18 and zfs 0.7.11. Now my syslog shows the following, if I search for noop:

root@omv4:~# cat /var/log/syslog | grep noop
Oct  2 08:59:45 omv4 kernel: [    1.121711] io scheduler noop registered

Seemingly this works now.
