Openzfs vs zfs on linux3/16/2023 Pool state can be checkpointed, allowing rewind later. Reduce memory used by removed devices when their blocks are freed or remapped. Top-level vdevs can be removed, reducing logical pool size. Space/object accounting based on project ID. Userobj_accounting (read-only compatible) Retain hole birth txg for more precise zfs sendĮnhanced dataset functionality, used by other features.īlocks which compress very well use even less space. Spacemap_histogram (read-only compatible) This system supports ZFS pool feature flags. Since version 0.6.1, ZFS is considered "ready for wide scale deployment on everything from desktops to super computers" stable for wide scale deployment, by the OpenZFS Project. There are out-of-tree Linux kernel modules available from the ZFSOnLinux Project. 4.2.1.5 Four hard drives (STRIPED MIRROR)Ī detailed list of features can be found in a separate article.3.2.1 Installing into the kernel directory (for static installs).Today, a growing community continues development of OpenZFS across multiple platforms, including FreeBSD, Illumos, Linux and Mac OS X. Subsequent releases of Solaris have included fewer and less ambitious changes. The first release of Solaris included a few innovative changes that were under development prior to the mass resignation. The 1/3 of the ZFS core team at Oracle that did not resign continue development of an incompatible proprietary branch of ZFS in Oracle Solaris. Most of them took jobs at companies which continue to develop OpenZFS, initially as part of the Illumos project. The Illumos project started to replace OpenSolaris and roughly 2/3 of the core ZFS team resigned, including Matthew Ahrens and Jeff Bonwick. Oracle purchased Sun Microsystems in 2010 and discontinued OpenSolaris later that year. Brian Behlendorf at LLNL started the ZFSOnLinux project in 2008 to port ZFS to Linux for High Performance Computing. Pawel Jakub Dawidek ported ZFS to FreeBSD in 2007. It was released under the CDDL in 2005 as part of OpenSolaris. Automated simulations of worst case scenarios before shipping code is important.ĭevelopment of ZFS started in 2001 at Sun Microsystems.File-systems should never be taken offline for repair.Redundancy should be handled by the filesystem.Administration of storage should be simple.Menuentry "Gentoo - 5.15.ZFS is a next generation filesystem created by Matthew Ahrens and Jeff Bonwick. Make sure your system BIOS/UEFI is set up to boot UEFI devices,Īfter you boot into the Live CD, make sure that you booted into UEFI mode by typing the following: You may need to disable Secure Boot if thatĬauses your USB to be rejected. On your system and get to the live environment. Since this is highly computer dependent, you will need to figure out how to boot your USB I install Gentoo, not exactly the way the handbook has it. Only be provided from me when the above configuration is used. You are free to substitute any of the above for whatever you want. Your swap partition is outside of ZFS and on a dedicated partition.The /boot/efi is an unencrypted FAT32 partition as per UEFI spec.The /boot pool is featureless and unencrypted.Only installing Gentoo on a single drive (Multiple drives in the same pool should automatically work).This should be all that's necessary to have a bootable USB. Select your USB Device from the Device drop down.Rufus is the USB Utility I recommend when on Windows. After that, we'll use it to make a bootable USB.įor the following commands, we will assume that your USB is /dev/sdg. You can download the "Admin CD" from the Gentoo Downloads page. Luckily, the Gentoo Admin CD provides the needed packages. You will need an ISO that contains OpenZFS. * /, /home on ZFS (Encrypted ZFS if desired) * /boot on ZFS (Featureless & Unencrypted) * UEFI-GPT (EFI System Partition - Unencrypted FAT32 partition as per UEFI Spec) This guide will show you how to install Gentoo Linux on x86_64 with: 1.9.6 Other stuff you might want to install.1.9.3 Take a snapshot of your new system.1.9.1 Remove zpool.cache refresh flag from bootloader configuration.1.8.15 Generate the initramfs and move the file to its correct location.1.8.14 Generating new zpool.cache file before/after reboot.1.8.13 Make the GRUB 2 configuration file.1.8.12 Installing the bootloader onto your drive.1.6.4 Set the bootable flag on the ESP partition.1.5 Confirm that you booted in UEFI Mode.
