Setting the acltype property to posixacl indicates Posix ACLs should be used.

Disable read prefetch because it is almost completely useless and does nothing in our environment but work the drives unnecessarily.

We use SATA drives which do not accept command tagged queuing, therefore set the min and max pending requests to 1.

Since this is a dedicated storage node, I can get away with this.

Set ARC cache min to 33% and max to 75% of installed RAM.

It is safe to change this on the fly, as ZFS will compress new data with the current setting: You can also use lz4 compression on later versions of ZFS as it can be faster, especially for incompressible workloads. Zpool create -f sp1 mirror A0 B0 mirror A1 B1Įnable ZFS compression to save disk space: Make sure to run udevadm trigger after creating nf. You want to create mirrored devices across controllers to maximize performance. NOTE: Check the latest ZFS on Linux FAQ about configuring the /etc/zfs/nf file. This is a simple example of 4 HDDs in RAID10.

Create ZFS storage pool, in below examples it will be named sp1.

Reboot to allow all changes to take effect, if desired.

Yum install zlib-devel libuuid-devel libblkid-devel libselinux-devel parted lsscsi

Openzfs compression install#

Note we have a few preliminary packages to install before we can compile. Remove the static module RPM and install the rest.

The following commands create two source & five binary RPMs.

(applies to ZFSoL before 0.6.3, xattr=sa is safe to use on 0.6.3 and later) If you plan to use the xattr=sa filesystem option, make sure you have the ZFS fix for so your symlinks don't get corrupted. Remove the static module RPM (we are using DKMS) and install the rest:

The following commands create two source & three binary RPMs.

Openzfs compression upgrade#

We want automatically rebuild the kernel modules when we upgrade the kernel, so you definitely want DKMS with ZFS on Linux.

Openzfs compression download#

Download & unpack latest SPL and ZFS tarballs from.

Or you can roll your own if you want specific patches: yum groupinstall "Development Tools"

Assumption is that your hostname is gfs01įor RHEL6 or 7 and derivatives, you can install the ZFSoL repo (and EPEL) and use that to install ZFSĪnd skip to Finish ZFS Configuration below.There are some commands which were specific to my installation, specifically, the ZFS tuning section. This is a step-by-step set of instructions to install Gluster on top of ZFS as the backing file store.

Point releases are tagged as needed in order to support the stable kernel available from. Ubuntu is not supported by OpenZFS, issues on Ubuntu should first be reported to Ubuntu’s bug tracker for ZFS.Įvery Linux release includes a range of supported kernels. These distributions have repositories provided directly by the OpenZFS community, while other distributions likely will work, they are not frequently tested and may exhibit issues, especially Ubuntu due to their HWE kernel pulling in patches from newer kernels and still claiming the kernel is from an older branch. New MINOR releases are planned to occur roughly annually. When a new MINOR release is tagged the previous MINOR release will no longer be maintained (unless it is an LTS release). This branch includes support for the latest OpenZFS features and recently releases kernels. OpenZFS current - Tracks the newest MAJOR.MINOR release. LTS releases will receive patches for at least 2 years. New kernel versions released after the OpenZFS LTS release are not supported unless there is not a newer current release. Minor changes to support these distribution kernels will be applied as needed. This branch is intended for use by distributions which use an LTS, enterprise, or similarly managed kernel (RHEL, Ubuntu LTS, Debian).

Openzfs compression Patch#

OpenZFS LTS - A designated MAJOR.MINOR release with periodic PATCH releases that incorporate important changes backported from newer OpenZFS releases. Linux and FreeBSD are officially supported, with plans to support macOS in the future. It includes protection against data corruption, support for high storage capacities, efficient data compression, snapshots and copy-on-write clones, continuous integrity checking and automatic repair, encryption, remote replication with ZFS send and receive, and RAID-Z. OpenZFS is an open-source storage platform that encompasses the functionality of traditional filesystems and volume manager. This site uses Just the Docs, a documentation theme for Jekyll.
