Lightbulb ZFS and Slackware


I know this attempt to create an installation with ZFSOnLinux with a Fedora live CD worked fairly well for the person who did it:

But could something similar be done with Slackware without access to a LiveDisk?

It looks possible. Check that any dependencies are solved or just try it and see where it complains.

You missed the reboot to the real install part. The live cd is only to be used to install your OS.

I am pretty sure it can be done more "Simply" and "directly" on Slackware through a different approach. I hate doing things the way some other hacker does it and tells you to do the same step by step.

I am pretty sure there are people in this forum that have done it before as well...
ZFS is the shit.

Er - is that also slang ? I understand that the ENTIRE purpose of this forum is to help people do things - ie show them the steps needed to get something to work. Obviously you've written more slang, and not being American I just don't understand it. At a guess, because "the shit" means something really good, I'm suspecting that "I hate" means "I really appreciate all the effort you guys (and gals) put into your explanations !

You guys are funny. The topic is ZFS not me.

Guys, please stay on topic. Don't need my own thread locked by unSpawn when I'm wondering if and how ZFS could be imported to a working Slackware install.

Have you considered virtualising Solaris and exporting ZFS via NFS back to the Slackware host? You would probably need to reserve a disk for the virtual machine. That way you get the real ZFS, and the overhead should be quite low if you run Solaris headless with KVM-Qemu (although I gather ZFS is CPU- and memory-intensive).

This is more or less how I intend to do it when I get time to learn more about ZFS, except that I will probably go with NetBSD and Xen, and export the ZFS data share via NFS to multiple domUs (guests), including, of course, Slackware!

Needless to say this would work only for data, not for system partitions, but at least you would get all the benefits of ZFS for your data.

A FreeBSD 9.0 VM is also an option; I believe ZFS in FreeBSD 9.0 is quite close to Solaris now.

I'd rather avoid using a VM if at all possible and use native disk arrays.

Six of one, half-a-dozen of the other. A VM might virtualise the controller, the memory, and CPU, but it does not virtualise or alter the on-disk format of a filesystem. A ZFS array inside a VM is the very same as a native ZFS array. To my mind that is better than grafting ZFS onto Linux. Linux already tries too hard to be all things to all people; I prefer integrating the strengths of each OS into a VM cluster.

My opinion on using ZFS for Linux? I would not go for it I have read some stuff on Red Hat website of its negative effects to your system.

I personally would choose BTRFS to try it if EXT4 is not good enough. You can also try to config ext4 system I think that is a healthier choice.

Can you provide a link to the "stuff" on Redhat's website? I'd like to read it as well. Thank you.
