I'd like to report that we've had success in setting up an
ldiskfs MDT and zfs OSTs on a single node with the
version lustre 2.4 g1cff80a. Something must have been
fixed/changed in this tree since the install steps didn't
change as far as I can tell.
Also, I was making rpms from spl and zfs sour
Hello Anjana,
I can confirm that this setup works (ZFS-MGS/MDT or LDFISKFS-MGS/MDT and
ZFS-OSS/OST)
I used a Cent OS 6.4
build:
2.4.0-RC2-gd3f91c4-PRISTINE-2.6.32-358.6.2.el6_lustre.g230b174.x86_64
and the Lustre Packages from

The bug was introduced on Sep. 10 and reverted on Sep. 24, so you hit
the lucky window. :)

I would check to make sure your ldev.conf file is set up with the
lustre-ost0 and host name properly.

The git checkout was on Sep. 20. Was the patch before or after?
The zpool create command successfully creates a raidz2 pool, and mkfs.lustre
does not complain, but

I'm guessing your git checkout doesn't include this commit:
* 010a78e Revert "LU-3682 tunefs: prevent tunefs running on a mounted device"
It looks like the LU-3682 patch introduced a bug that could cause your issue,
so its reverted in the latest master.

Here is the exact command used to create a raidz2 pool with 8+2 drives,
followed by the error messages:
mkfs.lustre --fsname=cajalfs --reformat --ost --backfstype=zfs --index=0
--mgsnode=10.10.101.171@o2ib lustre-ost0/ost0 raidz2 /dev/sda /dev/sdc

In theory this should be possible, but we have not tested this for a long time
since it isn't a configuration that is common.
Note that you need to configure the OST on a separate node from the MDT in this
case. We have not implemented the ability to have multiple OSD types on the
same node. I
Is it possible to configure the MDT as ldiskfs and the OSTs with zfs
in lustre 2.4? The server is running a lustre kernel on a Centos 6.4
system, has both lustre-osd-ldiskfs and lustre-osd-zfs rpms installed.
The MDT is up as ldiskfs, but get an error trying to configure the ost:
mkfs.lustre --fsn
