I'm using ZFS On Linux with CentOS 6 since almost two years. http://zfsonlinux.org/ I'm not using it to boot from it or for any vm stuff, but just for storage disks.

Recently updated to ZOL version 0.7.9. To install, I simply follow the instructions from this page: https://github.com/zfsonlinux/zfs/wiki/RHEL-and-CentOS Apply the modifications listed in the section "kABI-tracking kmod". For CentOS 6, after installation, make sure to run the following: $ service zfs-import start $ service zfs-mount start $ service zfs-share start $ service zfs-zed start $ chkconfig zfs-import on $ chkconfig zfs-mount on $ chkconfig zfs-zed on $ chkconfig zfs-share on

I played a bit with it on CentOS 7, with older ZOL version 0.7.4. Again, follow instructions in the section "kABI-tracking kmod". For CentOS 7, after installation, make sure to run the following: $ systemctl preset zfs-import-cache zfs-import-scan zfs-mount zfs-share zfs-zed zfs.target $ systemctl enable zfs-import-scan

Hope this helps.

Patrick.

I think the simplest solution would be to add this (which I haven't tried):

http://zfsonlinux.org/ https://github.com/zfsonlinux/zfs/wiki/RHEL-and-CentOS

to the Available Repositories for CentOS wiki page:

https://wiki.centos.org/fr/AdditionalResources/Repositories/

unless someone with some authority says that you can't do this.

Sure, this is the simplest path. Anyone has a good reason to be against it? That said, I keep the idea that SIG would be highly preferable. Anyone is using ZFS on this list? Any ideas? Thanks.

But besides this issue it was in my experience rock solid.

Watch out, ZFS on Linux is not as good as on FreeBSD/Solaris. Just recently there was an issue with data loss. https://github.com/zfsonlinux/zfs/issues/7401

Hi list, we all know why ZFS is not included in RHEL/CentOS distributions: its CDDL license is/seems not compatible with GPL license.

I'm not a layer, and I do not have any strong opinion on the matter. However, as a sysadmin, I found ZFS to be extremely useful, especially considering BTRFS sad state. I would *really* love to have ZFS on Linux more intergrated with current CentOS.

From what I know (and I can go wrong, obviously), while the incompatible licenses prevent CentOS from shipping it, nothing should prevent to have a package for enabling *its repository*, better yet the kmod-enabled one. I was thiking to something as a ZFS SIG, where we can simply issue "yum install zfs-sig" and have the correct kmod-enabled repository enabled.

I searched the list but I did not found anything regarding native ZFS. Any feedback on the matter is welcomed. Thanks.
