Lustre 1.6 Operations Manual

8. 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 mdsnode@tcp0:/datafs /mnt/datafs
6.1.2.3 Configuring Lustre with a CSV File
A new utility (script) - /usr/sbin/lustre_config can be used to configure
Lustre 1.6. This script enables you to automate formatting and setup of disks on
multiple nodes.
Describe your entire installation in a Comma Separated Values (CSV) file and pass it
to the script. The script contacts multiple Lustre targets simultaneously, formats the
drives, updates modprobe.conf, and produces HA configuration files using
definitions in the CSV file. (The lustre_config -h option shows several samples
of CSV files.)
Note – The CSV file format is a file type that stores tabular data. Many popular
spreadsheet programs, such as Microsoft Excel, can read from/write to CSV files.
How lustre_config Works
The lustre_config script parses each line in the CSV file and executes remote
commands, like mkfs.lustre, to format each Lustre target in the Lustre cluster.
Optionally, the lustre_config script can also:
■
■
■
■
■
Verify network connectivity and hostnames in the cluster
Configure Linux MD/LVM devices
Modify /etc/modprobe.conf to add Lustre networking information
Add the Lustre server information to /etc/fstab
Produce configurations for Heartbeat or CluManager
