Lustre installation (multi node)
I had earlier posted a demo of installation of lustre on a single node.
But most, if not all production installations of lustre are on multiple nodes - tens of Object Storage Servers (OSS) and thousands of clients.
Here is a demo of a multi node setup - though on a much lesser scale - one Meta Data Server (MDS), two OSS and a single client. And I show this on VMWare. I take three virtual machines on which lustre 1.6 packages are installed. (See earlier post on how to do this.
Lustre Installation
Here is what the demo does:
MDS (nodename: lin1)
--------------------
mkfs.lustre --reformat --device-size=300000 --fsname lustre --mdt --mgs /tmp/lustre-mdt
mkdir -p /mnt/mds
mount -t lustre -o loop /tmp/lustre-mdt /mnt/mds
df -h
OSS 1 (nodename: lin2)
-----------------------
mkfs.lustre --reformat --device-size=1000000 --fsname lustre --ost --mgsnode=lin1@tcp0 /tmp/lustre-ost1
mkdir -p /mnt/ost1
mount -t lustre -o loop /tmp/lustre-ost1 /mnt/ost1
OSS 2 (nodename: lin3)
-----------------------
mkfs.lustre --reformat --device-size=1000000 --fsname lustre --ost --mgsnode=lin1@tcp0 /tmp/lustre-ost2
mkdir -p /mnt/ost2
mount -t lustre -o loop /tmp/lustre-ost2/mnt/ost2
Client (nodename: lin3)
-----------------------
mkdir -p /mnt/lustre
mount -t lustre lin1@tcp0:/lustre /mnt/lustre
dd if=/dev/zero of=/mnt/lustre/foo bs=1024k count=100
lfs getstripe /mnt/lustre/*
Can I ask and share a few of my queries and certain errors with you, regarding Lustre and its installation
Cheers,

Bibu,
You can ask questions at lustre-discuss@lustre.org. You must subscribe to the list first though.
