[Bug 1852119] Re: Please add zfs modules to linux-raspi2
Raspberry Pi4 is already available with 8GB of memory. Now that we are way over the minimal memory requirements of ZFS, I think this topic should be reconsidered. Using zfs-dkms is a bit tedious, having the ZFS kernel modules available with the arm64 standard kernel would make the life much easier. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1852119 Title: Please add zfs modules to linux-raspi2 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-raspi2/+bug/1852119/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1852119] Re: Please add zfs modules to linux-raspi2
Thanks for the policy clarification. But as I understand it "4 GiB of memory is recommended for normal performance in basic workloads" referred to 4Gb of memory in total, not 4gb of free memory. I'll ask again once there is a device with more than 4Gb of RAM, but FYI, since the raspberry pi may often be used for single tasks, a 4Gb ram machine might be just fine with that zfs overhead. (I haven't seen any memory pressure issues with multiple headless 4Gb Pi4 machines running with ubuntu on zfs.) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1852119 Title: Please add zfs modules to linux-raspi2 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-raspi2/+bug/1852119/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1852119] Re: Please add zfs modules to linux-raspi2
The Ubuntu kernel team recommends to have at least 4GB of free memory to run ZFS on slow backing store devices for nominal performance. Since there is OS overhead (kernel, userspace processes etc) a 4GB Raspberry Pi will perform sub-optimally. Note that the document you referenced in commet #1 states: "Computers that have less than 2 GiB of memory run ZFS slowly. 4 GiB of memory is recommended for normal performance in basic workloads. " Once you start to add in ZFS options such as compression and/or run scrubs on a slow device it is likely you may start to see high memory pressure issues occurring. Hence we do not support ZFS unless you have at least 4GB of memory free. ** Changed in: linux-raspi2 (Ubuntu) Status: Confirmed => Won't Fix ** Changed in: linux-raspi2 (Ubuntu) Importance: Undecided => Wishlist -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1852119 Title: Please add zfs modules to linux-raspi2 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-raspi2/+bug/1852119/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
