Re: ZFS on Centos 8 / RHEL 8
hey ... it looks like its working! I've used ZFSonLinux for Fedora 28 (DKMS)... compilation went smooth... I see the datasets. More testing to come.

Re: ZFS on Centos 8 / RHEL 8 [minihowto]
Exactly what I'm waiting for. Any idea when they'll formally support RHEL 8?
In my search I also found this: https://www.phoronix.com/scan.php?page= ... .0-Problem
A bit concerning. I just switched from FreeBSD to CentOS 8 so trying to understand what kind of ZFS support I can get on the platform...

Re: ZFS on Centos 8 / RHEL 8 [minihowto]
I truly like the ZFSONLINUX implementation. Unlike FreeBSD, it can handle LONG dataset/volume names (supercool) and in its last version (0.8.x) you can remove devices in ZPOOLs(!).JanusAlpha wrote: ↑2019/09/26 20:54:09A bit concerning.

Also, they have (finally) implemented the TRIM.
see: https://github.com/zfsonlinux/zfs/relea ... /zfs-0.8.0
ad. your link.. it does not apply to RHEL8/CentOS8, because it affects the 5.x (eg. newer) kernels only.

Re: ZFS on Centos 8 / RHEL 8 [minihowto]
Forgive my ignorance but doesn't RHEL kernel evolve over time? I.e. over its lifespan will it not progress to 5.x?

Nope.
If it starts in 8.0 with version X , it will stay version X till it dies (only minor version changes)
This provides safety that your hardware + software will be OK untill EOL of the OS.

Unless you enable the "CR" repository, but it is a little bit risky in production.
For example I have a normal Centos7 machine in production with a standard 3.xx kernel
and on my personnal laptop, I enabled CR repository which gave me the possibiliy to switch to kernel 4.xx
