Re: [lustre-discuss] Using lctl lfsck syntax issues

[Andreas Dilger]

The lctl commands need to be run on the MDS.

Re: [lustre-discuss] lustre vs. lustre-client

[Brian Andrus]

IIRC, that is so, when you install the lustre server package, it also 
covers the dependency on lustre-client that other packages may have.  If 
you look further down in the spec file, you see that:


%if %{with servers}
Requires: lustre-osd
Requires: lustre-osd-mount
Provides: lustre-client = %{version}-%{fullrelease}
%endif

Are there sites that build both with and without servers, and need to keep

[lustre-discuss] Using lctl lfsck syntax issues

[Ms. Megan Larko]

Howdy List!

I am checking Lustre-2.10.4 (kernel 3.10.0-693 on CentOS 7.3.1611).
I am having trouble using lctl lfsck.  I believe I am not using the proper
syntax.  The manual page, "man 8 lctl-lfsck-start" (or query in place of
start) is not providing me the info I seek (or rather I just am not
'getting' it).

All of my queries (shown below) have the same response.
> lctl lfsck_query -t namespace --device meg1-MDT
Fail to query LFSCK: Invalid argument
> lctl lfsck_query --device meg1-MDT
Fail to query LFSCK: Invalid argument
> lctl lfsck_query -M meg1-MDT
Fail
> lctl lfsck_query -M 4# lctl dl shows MDT as device num. 4
Fail 

I am running this on the Lustre client.  The lctl command is from:
> rpm -qf /usr/sbin/lctl
lustre-2.10.4-1.el7.centos.x86_64

I would like to test the lsfck_query|start|stop function.

P.S.  Can an actual--non-dryrun--lfsck be run on a mounted active Lustre
File System?

Cheers,

[lustre-discuss] ksym errors on kmod-lustre RPM after 2.10.4 build against MOFED 4.3

[Ms. Megan Larko]

Hi!

I concur with Gin Tan.

I built my successful Lustre-2.10.4 on an older linux-3.10.0-693.[ 2.2..x
or 17.1 ].
After booting into the 693 kernel, I then built MLNX_OFED_LINUX-4.3-1.0.1.0
via command:
"./mlnxofedinstall --skip-distro-check --add-kernel-support"

Then I start that version of mlnx (/etc/init.d/openibd start).

Then I build spl and zfs if the box is a Lustre server.
I go right to building Lustre if the goal is to install a client.

Lustre Client:
./configure --disable-server --disable-ldiskfs
--with-o2ib=/usr/src/ofa_kernel/default
--with-linux=/usr/src/kernels/3.10.0-693.17.1.el7.x86_64

Then the usual and customary "make" and "make rpms".
I do have a kmod-lustre-* rpm.   I have no symbol errors and my test bed of
Lustre-2.10.4 is behaving nicely.

I have found that order matters.  I seem to need to do the kernel first,
then Mellanox on that kernel and build the Lustre part on the kernel with
the new MLNX active.

Cheers,
megan

Hi Eli,

It looks like video links for the first day are up here:

http://opensfs.org/lug-2018-agenda/

I know that Kevin Harms has been working hard with Ken Rawlings to get these 
video recordings edited and online.  I would expect to see more video links 
there soon.

Re: [lustre-discuss] lustre-discuss Digest, Vol 149, Issue 5

[Gin Tan]

Had the same issue, it was because I still had the kernel modules loaded
while building the RPMs.

Uninstalled kmod-lustre and re-compiled fixed the ksym issues.

Also, there's a page allocation issue with MoFED 4.3, use MoFED 4.4.
