Problem to build Lustre client 2.7.0 with OFED on CentOS
by David Roman
Hello,
I want compiled Lustre Client 2.7.0 with OFED-3.18-rc3 under Centos 6.6 (2.6.32-504.8.1.el6.x86_64 x86_64)
# rpm -qa | grep kernel

I install OFED-3.18-rc3

Re: [HPDD-discuss] Trying to rebuild all Lustre rpms with zfs 0.6.4.2 -- and failing
by Bob Ball
Hi, Ned,
So, it seems that you are saying, for OSS that utilize zfs, not ldiskfs,
then I can use a stock kernel and just add the Lustre rpms on top? That
is not something that I had ever considered, but then, we've only gone
to zfs since Lustre 2.7.0 came out. I will try to devise a test of this.
It is frustrating though, to follow these Twiki procedures, and end up
with a kernel that does not seem to understand the LVM disks underlying,
even though it was built on that same machine. It just seems wrong.

Re: [HPDD-discuss] Lustre 1.8.9 wc1 for Kernel 2.6.32-504 - again
by Chris Hunter
We apply patch for LU2800 & LU5237 (b2d09eb6,diff?) to git b1_8 branch.
A couple optional patches for LU3067 & LU3596 are available. It has
become difficult to build 1.8 clients with recent redhat kernels (they
tend backport fixes from the 3.10 kernels).
We have not moved to newer client version because of support for legacy
OS and (perceived) client performance issues with 2.1/2.4/2.5 versions.
IMO the b2_5 client issues appear to be resolved so that's likely our
upgrade path.
Note it appears the b1_8 branch was closed last month and all open pull
requests were abandonded.
regards,

Load balancing between routers
by Jose Manuel Martínez
Hello everybody.
I'm configuring two servers as lustre routers (Lustre 2.7) in order to
join TCP and IB networks. The documentation says that many routes can be
configured for LNET with or without priorities.
My question: If I don't specify any priority (both routers will have the
same priority), is there any kind of load balancing between routers?. Or
should I do it 'handmade', specifying different priorities for different
group of clients and servers?.
Thank you everybody.

One of several Clients failing to mount handful OST's
by Kumar, Amit
Dear All,
Is this link(http://wiki.old.lustre.org/manual/LustreManual20_HTML/LustreTroubles... the most up to date list of error messages? I remember looking up a header file that had these defined as well, but can't seem to recall which one it was now?
One of over 1000 clients is being stubborn on mounting a handful OST's(total of 4 out of 77) .
We had a maintenance and this server was forced to shut down, as it wouldn't. Now that rest of them have rebooted successfully I can't figure out why this is stuck. It seems to me that MDS has set these OST's as read only for this specific client because it was forced to shut down, not sure if this is that case?
Below is what I find:
Client Machine> #lfs df -h
.....
OST001b : inactive device
...
OST001d : inactive device
....
OST0027 : inactive device
....
OST002c : inactive device
They mount perfectly on other clients.
I have made sure that these devices are up/active on MDS.
Below are relevant messages when I mount the file system on the client. Below here I am showing message logs from MDS,OSS and Client

[PATCH] staging: lustre: drop redundant check
by Viresh Kumar
There is no need to verify that its an error, as we are anyway going to
match the error value to -ENOENT. Drop the redundant check.

[PATCH 10/15] drivers: staging: Drop unlikely before IS_ERR(_OR_NULL)
by Viresh Kumar
IS_ERR(_OR_NULL) already contain an 'unlikely' compiler flag and there
is no need to do that again from its callers. Drop it.
This also replaces an IS_ERR(x) + (x == NULL) check to IS_ERR_OR_NULL
check.
