[lustre-discuss] ZFS-lustre setup falis for me

[Clark, Nathaniel L]

https://wiki.hpdd.intel.com/display/PUB/Lustre+Support+Matrix

el7.2 isn't supported until 2.8.  I would suggest pulling down the official RPMs

https://downloads.hpdd.intel.com/public/lustre/latest-release/el7/server/RPMS/x86_64/

The following is all you'll need for ZFS support:
lustre-2.8.0-3.10.0_327.3.1.el7_lustre.x86_64.x86_64.rpm
lustre-dkms-2.8.0-1.el7.noarch.rpm
lustre-osd-zfs-mount-2.8.0-3.10.0_327.3.1.el7_lustre.x86_64.x86_64.rpm

Subject: [lustre-discuss] ZFS-lustre setup falis for me

Hello,
I am trying to deploy a small cluster with "zfs on lustre" setup for initial testing a SSD solution.

I followed a few hints on the following resources:

http://zfsonlinux.org/lustre-configure-single.html
http://zfsonlinux.org/lustre.html


I am working on rhel7

I installed the following ZFS rpm:

dkms-2.2.0.3-30.git.7c3e7c5.el7.noarch.rpm
libnvpair1-0.6.5.6-1.el7.centos.x86_64.rpm
libuutil1-0.6.5.6-1.el7.centos.x86_64.rpm
libzfs2-0.6.5.6-1.el7.centos.x86_64.rpm
libzpool2-0.6.5.6-1.el7.centos.x86_64.rpm
spl-0.6.5.6-1.el7.centos.x86_64.rpm
spl-dkms-0.6.5.6-1.el7.centos.noarch.rpm
zfs-0.6.5.6-1.el7.centos.x86_64.rpm
zfs-dkms-0.6.5.6-1.el7.centos.noarch.rpm

ZFS itself is working fine.
I can create zpools and they are working.

So I did proceed with Lustre.
I did not proceed installing the Lustre official rpm, but I went for the lustre rpm which are inside the ZFS on linux repo.
So I installed:

lustre-2.5.3-1zfs.x86_64.rpm
lustre-dkms-2.5.3-1zfs.el6.noarch.rpm
lustre-iokit-2.5.3-1zfs.x86_64.rpm
lustre-osd-zfs-2.5.3-1zfs.x86_64.rpm
lustre-tests-2.5.3-1zfs.x86_64.rpm

I went on configuring mds and oss.

when I create the lustre/zfs file system for mgs:

mkfs.lustre -€“mgs -€“backfstype=zfs psanatest-mgt0/mgt0 /dev/vdb Bus error (core dumped)

Do you have any hints ? Any how-to I could/should look for ?
zfs is a requirement for me.

thank you very much


Riccardo
