Re: [lustre-discuss] MDS Config Help: Are the lustre modules loaded?

2016-06-22 Thread Sangeetha Banavathi Srinivasa

I checked the output of dmesg and found
lnet: Unknown parameter `#’

The error was caused due to a comment that was inserted in 
/etc/modprobe.d/lustre.conf

Thanks a lot for your time and your help.

Re: [lustre-discuss] MDS Config Help: Are the lustre modules loaded?

2016-06-22 Thread Patrick Farrell

OK, that's not the error we started with. You were having a problem
loading modules, but aren't now. (probably)

The error output from that command is bad. It asks if the modules are
loaded, but that doesn't mean they aren't.

"No such device" is probably the key here. I'd look at the arguments to
the mount command. Does /dev/vg00/mdt1 exist and is it set up
correctly? How about the mount point, /mdt?

That needs to match the kernel version in the Lustre RPMs. (The

In fact, it looks like you've got Lustre server RPMs, given the
_lustre in the name of the kernel. That means you need to
install the associated kernel.

So, compare your kernel version and your Lustre RPMs.

Hm. It sounds like your RPMs are not installed correctly, but I vaguely
recall something about a packaging issue with the Lustre 2.8 release RPMs.

Perhaps someone else on the list can help further.

The kernel version is found with uname -r or cat /proc/version.

That needs to match the kernel version in the Lustre RPMs.  (The version 
string is the 2.6.32-573.12.1.el6_lustre) part.


In fact, it looks like you've got Lustre server RPMs, given the _lustre 
in the name of the kernel.  That means you need to install the 
associated kernel.

Well, it says to check dmesg...  Though that will just list the 
symbols.  In general, this usually means you've got a mismatch 
between the version of the kernel (or OFED) Lustre is built against 
and your version of either the kernel or OFED.  Given the number and 
locations of the mismatches, I'm guessing it's the kernel.


So, compare your kernel version and your Lustre RPMs.

Re: [lustre-discuss] MDS Config Help: Are the lustre modules loaded?

2016-06-22 Thread Sangeetha Banavathi Srinivasa

Patrick,

The CentOS version on the machines is 6.8

[lustre@hulk2 ~]$ cat /etc/redhat-release 
CentOS release 6.8 (Final)


The kernel version that I have installed is what I found along with the lustre 
RPMs
[lustre@amaranth3 ~]$ uname -r
2.6.32-573.12.1.el6_lustre.x86_64


And I am trying to install lustre 2.8.

Should the CentOS release version be 2.7??
