<TITLE>RE: [Lustre-discuss] Configuration of lustre FS on single node</TITLE>
</HEAD>
<BODY>
<!-- Converted from text/plain format -->
<P><FONT SIZE=2>hi,<BR>
/dev/sda is a non ext3 FS, that's the reason i think, my system crashed.<BR>
my linux fs is on /dev/sda8 and an ext3 one So should I go with<BR>
<BR>
$ mkfs.lustre --fsname spfs --mdt --mgs /dev/sda8<BR>
<BR>
and proceed?<BR>
<BR>
and Moreover, to run the llmount.sh or local.sh we should have lmc,lconf and lctl utilities, but these are not provided in lustre1.6.4.2, so that's why I'm going in this way.<BR>
<BR>
Thanks and Regards,<BR>
Ashok Bharat<BR>

Just looking at the command you tried :<BR>
> $ mkfs.lustre --fsname spfs --mdt --mgs /dev/sda<BR>
<BR>
You may have wrecked your root file system. Or is /dev/sda some other<BR>
device ?<BR>
<BR>
It may be simpler for you to try llmount.sh to get a simple setup of<BR>
lustre on a single node (with loop back mounts)<BR>
<BR>
thanks,<BR>
