RHEL 7.6 was released 5 days ago. I'm sure packages will be arriving soon, thanks for letting us know and keep your eyes peeled. :smile:

[tonyhutter]

Yea, it's on my TODO list. I need to put together the Fedora 29 packages as well. They will definitely be included with 0.7.12 (https://github.com/zfsonlinux/zfs/pull/8078).

[tonyhutter]

... sorry I mistakenly read this this as Centos 7.6 (before my morning coffee...) We don't provide RHEL packages, but do provide Centos 6 & 7 packages, so we'll support Centos 7.6 when it comes out.

[tonyhutter]

@johnpeeb this doesn't answer your question, but I wanted to mention that the kmods are not versioned to the kernel, but rather to the kernel functions they call. As long as those functions stay the same, then it should work. For example, zfs-kmod-0.7.12 works on both Centos 7 w/3.10.0-862.14.4 and 3.10.0-862.11.6.

Probably it's time to build el 7.6 kmod packages and zfs-release.el7_6.noarch.rpm soon, because CentOS 7 with incompatible Kernel already there via CR repo

still on CentOS 7.5.1804

[root@lp-hfischer-centos ~]# cat /etc/centos-release
CentOS Linux release 7.5.1804 (Core) 

but already continous release kernel of upcoming Centos 7.6.1810 install via CR repo:

Also the src packages for building zfs/spl kmod packages against the new kernel are already available via
http://vault.centos.org/7.5.1804/cr/Source/SPackages/

[hoonetorg]

CentOS 7.6.1810 released now (https://lists.centos.org/pipermail/centos-announce/2018-December/023082.html)
Now it's definitely :smiley: time to create the new kmod repo/packages/release(rpm) according to https://github.com/zfsonlinux/zfs/issues/8090#issuecomment-435949869.

[tonyhutter]

@hoonetorg thanks, I'll put together the RPMs.

[fmikker]

I wish I had checked if the 7.6 package was available before I did the upgrade, oh well, no biggie to revert.

[tonyhutter]

Ok packages should be up now.

https://github.com/zfsonlinux/zfs/wiki/RHEL-and-CentOS has been updated with the new 7.6 zfs-release rpm: http://download.zfsonlinux.org/epel/zfs-release.el7_6.noarch.rpm

Please post if you run into any issues

[GeoffreyMills]

FYI Cannot install the 7.5 or 7.6 releases on Centos 7. Can download and install the zfs-release rpm OK but the subsequent 'yum install zfs' fails, cannot download files. Seems like at least half of the 'spl', etc files are not found. The 7.4 release works OK

[tonyhutter]

@GeoffreyMills do a yum clean all and try again.

[GeoffreyMills]

Done, working now - thanks

Hi, have problem when trying to import module

/sbin/modprobe zfs
modprobe: FATAL: Module zfs not found.

I see module is in place (possibly modprobe works with different path ?)

locate zfs.ko
/usr/lib/modules/3.10.0-957.1.3.el7.x86_64/extra/zfs/zfs/zfs.ko

my kernel is 3.10.0-957.el7.x86_64

[omfdzg]

works fine after yum update
