[lustre-discuss] Issue with installing zfs on lustre

[Riccardo Veraldi]

you need to use 0.6.4.2

this because lustre has I/O performance issues with the latest ZFS 
version for linux.

I used ZFS 0.6.4 and it works.

only you have to build your own lustre 2.8.0  RPM and eventually build 
them without ldiskfs support.
I was not interested in ldiskfs so I just took it out.
The lustre.spec files from the src.rpm anyway has some issues, you will 
see it yourself so you will need
to tweak it a little bit, but it will work at the end.

I gave you very useful hints on how to go on.

So now you can do it yourself.
