[Lustre-discuss] Difficulties with initial install of Lustre

Adam,

I suspect that your network settings are misconfigured.

Do you have a line like:

options lnet networks=tcp0(ethX)

in your /etc/modprobe.conf, where ethX is the Ethernet device associated
with your hostname of cf2?

Also, make sure, if this is a redhat system, that your hostname is not
associated with the localhost entry in /etc/hosts...

I suggest this because I see 127.0.0.1 related connection attempt
messages in the logs you sent.

Fergal.

Subject: [Lustre-discuss] Difficulties with initial install of Lustre

Greetings all,

I''ve read through the documentation and the email list archive for the
last 
few months but I am still having trouble getting Lustre running on a
single 
system - for test purposes only.

I have installed the RHEL 2.6.9-22.0.2 i686 kernel and associated
modules 
for Lustre 1.4.6.  I have created an xml file based on the Single Node 
Client, MDS and Two OSTs in the docs.  I could not find the utilities
for 
''lwizard'' or the lustre-lite-utils with a matching version
number.
(1.4.6)

Situation:
When I execute ''lconf --reformat cf2.xml'', all seems to go
well until
the 
first NETWORK: line.  The line before it in the example shows a
''llite''
modules being loaded, I do not show that module as being loaded - I
assume 
it is part of the Lustre-lite utilities which, I hope, are not necessary

and that is why I couldn''t locate them.

On the NETWORK line itself, mine differs from that shown in the 
documentation at the end of the line:
Docs: ''NETWORK: NET_host_tcp NET_host_tcp _UUID tcp host 988''
Mine: ''NETWORK: NET_cf2_tcp NET_cf2_tcp_UUID tcp cf2''

The next few lines in the docs show OSD and OST message before showing a

MDSDEV: line.  I do not have those in my output and suspect that this is
a 
major clue as to my troubles.  I include the console error output below
as 
well as my lmc commands that I used to make my xml file.

Note: lconf does not finish, it keeps running and generating console
errors 
- I assume because it cannot complete the connection it is attempting.

All help and suggestions are appreciated.

[Lustre-discuss] Difficulties with initial install of Lustre

Thank you, Fergal.

I have made the following changes to my system and all seems to work now:

Added line to /etc/hosts
192.168.1.20 	cftest #IP address for eth0

Changed XML file, replacing all instances of ''cf2'' with
''cftest'' and saved
as cftest.xml

Added ''options lnet networks=tcp0(eth0)'' to /etc/modprobe.conf

Executed ''lconf -d --node cf2 cf2.xml''

Executed ''lconf --reformat --node cftest --verbose cftest.xml

Much more output, I now see the OST and OSD lines and it formatted and 
mounted the cluster.

I have run some of the tests and they are returning proper results.  I 
shall now proceed to set up a multiple machine cluster for more thorough 
testing.

Thank you again for your assistance.

Adam

[Lustre-discuss] Difficulties with initial install of Lustre

Greetings all,

I''ve read through the documentation and the email list archive for the
last
few months but I am still having trouble getting Lustre running on a single 
system - for test purposes only.

I have installed the RHEL 2.6.9-22.0.2 i686 kernel and associated modules 
for Lustre 1.4.6.  I have created an xml file based on the Single Node 
Client, MDS and Two OSTs in the docs.  I could not find the utilities for 
''lwizard'' or the lustre-lite-utils with a matching version
number. (1.4.6)

Situation:
When I execute ''lconf --reformat cf2.xml'', all seems to go
well until the
first NETWORK: line.  The line before it in the example shows a
''llite''
modules being loaded, I do not show that module as being loaded - I assume 
it is part of the Lustre-lite utilities which, I hope, are not necessary 
and that is why I couldn''t locate them.

On the NETWORK line itself, mine differs from that shown in the

Docs: ''NETWORK: NET_host_tcp NET_host_tcp _UUID tcp host 988''
Mine: ''NETWORK: NET_cf2_tcp NET_cf2_tcp_UUID tcp cf2''

The next few lines in the docs show OSD and OST message before showing a 
MDSDEV: line.  I do not have those in my output and suspect that this is a 
major clue as to my troubles.  I include the console error output below as 
well as my lmc commands that I used to make my xml file.

Note: lconf does not finish, it keeps running and generating console errors 
- I assume because it cannot complete the connection it is attempting.

All help and suggestions are appreciated.
