Lustre 1.6 Operations Manual

6.1.1.2 Configuration Generation and Application
1. Install the Lustre RPMS (per Installing Lustre) on all nodes that are going to be
part of the Lustre filesystem. Boot the nodes in Lustre kernel, including the
clients.
2. Change modprobe.conf by adding the following line to it.
options lnet networks=tcp
3. Configuring Lustre on MGS and MDT node.
$ mkfs.lustre --fsname datafs --mdt --mgs /dev/sda
4. Make a mount point on MDT/MGS for the filesystem and mount it.
$ mkdir -p /mnt/data/mdt
$ mount -t lustre /dev/sda /mnt/data/mdt
5. Configuring Lustre on all four OSTs.
mkfs.lustre --fsname datafs --ost --mgsnode=mds16@tcp0 /dev/sda
mkfs.lustre --fsname datafs --ost --mgsnode=mds16@tcp0 /dev/sdd
mkfs.lustre --fsname datafs --ost --mgsnode=mds16@tcp0 /dev/sda1
mkfs.lustre --fsname datafs --ost --mgsnode=mds16@tcp0 /dev/sdb
Note – While creating the filesystem, make sure you are not using disk with the
operating system.
6. Make a mount point on all the OSTs for the filesystem and mount it.
$ mkdir -p /mnt/data/ost0
$ mount -t lustre /dev/sda /mnt/data/ost0
$ mkdir -p /mnt/data/ost1
$ mount -t lustre /dev/sdd /mnt/data/ost1
$ mkdir -p /mnt/data/ost2
$ mount -t lustre /dev/sda1 /mnt/data/ost2
$ mkdir -p /mnt/data/ost3
$ mount -t lustre /dev/sdb /mnt/data/ost3
$ mount -t lustre mdt16@tcp0:/datafs /mnt/datafs
