Hi,
I'm trying to build lustre(1.6.4.2) version on 2.6.20.15 kernel on an x86 based machine.I'm using Ubuntu 7.10 flavour.
While applying patches to the kernel in the series which_patch file,under the supported kernels, vanilla-2.6.20.15.series is not menioned but vanilla-2.6.18-.series is mentioned.
So, can I proceed applying the series file of 2.6.18 version on a 2.6.20.15 version.
Regards,
Ashok Bharat

Hello,
I successfully build lustre(1.6.4.2) on my system for a patchless client But I dont know how to proceed in configuring the file system.
I'm trying to build all MDS,client and MDT's on a single node.
>From the tutorials I came to know that
First, create an MDT for the "spfs" file system that uses the /dev/sda disk. This MDT also acts as the MGS for the site.
$ mkfs.lustre --fsname spfs --mdt --mgs /dev/sda
But by triggering this command my system crashed in which the whole data is lost and again I need to install the OS.
I want help in proceeding of mounting a lustre file system.
Thanks and Regards,
Ashok Bharat

Hi-
I've had lustre running happily for some time over a single 10g ethernet NIC
per node. After switching to dual 10g and creating a new filesystem
(1.6.4.2), I'm seeing nothing but keep-alive packets with bad checksums.
What is the current "correct" way to do this now? The manual suggest not using
bonding, but several list postings now reccommend it. Without bonding, do I
need to have my 2 switches stacked, or will Lustre recognize the division in
my subnet?
LNET module options I've tried are:
1) networks="tcp0(eth2,eth3)"
2) ip2nets="tcp(eth2,eth3); tcp(eth2) 10.9.[1-4].*; tcp(eth3) 10.9.[5-8].*;"
and many other variations
All other services are functional on both interfaces.
Thanks in advance,

Today we are starting to see obd_change_cbdata errors on our MGS/MDT node.

Ashok,
Could you let us know what are the modules that you have installed on
the system. The linux version on your system. And the steps that you
have done so far.
thanks,

Hi,
the kernel version I used is 2.6.20.15 and the distro is Ubuntu 7.10
The steps so far I have done are:
1)I have downloaded the sources lustre(1.6.4.2) from CFS
2)I tried to build lustre for a patchless client in which i triggered the command,
[lustre]$ ./configure --with-linux=/unpatched/kernel/source
3)then I build it using make and then installed the modules using make install commands
(I'm not sure whether the modules are installed correctly or not.Isn't the modules are installed using make install cmd)
4)Now in /usr/lib there is a lustre folder created.
(Can we setup all MDS,client and OST's on a single system? my system configuration is Intel Pentium 512 MB RAM 1.6 GHz)
Could you please tell me how to mount lustre fs in my laptop.
Thanks and Regards,
Ashok Bharat
