Is ZFS supported in Kernel 4.13-4.15?

  • Guys looking at the status of the scrubs I noticed that I can upgrade my pool. Should I do it after the scrub? I don't have a backup of the data on my ZFS mirror, is it a risky operation?

    Intel G4400 - Asrock H170M Pro4S - 8GB ram - Be Quiet Pure Power 11 400 CM - Nanoxia Deep Silence 4 - 6TB Seagate Ironwolf - RAIDZ1 3x10TB WD - OMV 5 - Proxmox Kernel

  • yes, you can upgrade.


    it's not risky, only be sure that do not need to mount the pool in other O.S. that do not support the upgrade. EG: BSD

  • @Blabla Read five posts from here, I asked the same:

    For me it worked in under 5 seconds.

  • Is here anybody using kernel 4.17 in combination with zfs? Any problems?

    It seems to work fine on my test system but that isn't really the best use case. I still think the proxmox kernel is probably the best option if you use zfs.

  • Ok, thanks for confirmation. At the moment I am at backports kernel 4.16.


    There are always little changes for my digital devices dvb tuner card from kernel 4.13 to kernel 4.17. So I would like to use kernel 4.17 to get most stability and most features for my dvb card.


    But maybe the proxmox kernel 4.15 holds the most relevant changes I need. Will check that.


    Thank you!

    Because it is the Ubuntu 18 LTS kernel, it might have the changes backported to it.

    I'm using 4.17 with the ZFS 4.0.4 plugin, on my backup, but it's only been running for a week. (To be fair, that's not long enough to detect something subtle.) Given @ryecoaaron 's tweaks, I'm considering the proxmox kernel when I update my primary server.

  • Is here anybody using kernel 4.17 in combination with zfs? Any problems?

    I'm somewhat surprised to find; with OMV4 - Kernel 4.17 and the ZFS 4.0.4 plugin, that a ZFS mirror is running well on an Atom D525 processor with 4GB RAM. That's certainly not fast hardware.


    I still have a bit of testing to do, but it looks pretty good so far.

  • Because it is the Ubuntu 18 LTS kernel, it might have the changes backported to it.


    I had a look for a changelog.. all I could find is this: https://git.proxmox.com/?p=pve-kernel.git;a=summary

    Just bare in mind that the D525 doesn't have ECC.

    You would need to look at the changelog for Ubuntu instead of proxmox.

  • I got all excited then for a minute.. I thought Proxmox might offer some kind of livepatch, but their solution is to use Kernel Care ;-(


    This would be another win if OMV moved to Ubuntu. Canonical allow you to register 3 systems for free. That's probably one of the best automagic offerings going.

  • Hi Guys i did a fresh install and upgrade to 4.17 but can not get zfs plugin installed any tips?
