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