    I haven't had any. I've checked all status on the pools and they show healthy. And no errors so far.
    I've just rebooted after this last update and I'm still getting ZFS: Unable to set "noop" scheduler for /dev/sdd1 (sdd): 256 etc. for the pool

  • 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

  • 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:


    Code
    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.
