6.1- GPFS Implementation sample based on version 2.3.0.28

a) Increase /var size in all nodes (recovery area) (> 400MB)
b) Resize /tmp for more than 200MB (gpfs dump area)
c) Configure ntp
d) Setup etherchannel
e) Network tunning
no -r -o ipqmaxlen=512 ( we also recommend to verify at least RCF1323, tcp_recvspace and tcp_sendspace )

f) Setup FCs to fastfail
g) Setup ssh keys in all hosts
h) Add hosts in /etc/hosts
i) Verify if /usr/bin/ssh and /usr/bin/scp exist. If not, make soft links
j) Add this line in /etc/ssh/ssh_config ( sshd restart is not needed )
StrictHostKeyChecking no

k) Install the gpfs package and patches
l) Add path in /.profile-> PATH=$PATH:/usr/lpp/mmfs/bin
m) Assign necessary disks
1 or 3 disks for tiebreaker and others for data

n) Assign PVID for the disks
o) create /var/mmfs/etc/node.list like example below

server-a:quorum
server-b:quorum
server-c
server-d
server-e
server-f

p) create the gpfs cluster
mmcrcluster -p server-a -s server-b -n /var/mmfs/etc/node.list -r /usr/bin/ssh -R /usr/bin/scp -C cluster-name -A

q) check gpfs cluster
mmlscluster
mmlsconfig

r) Create the file to setup NSD ( /tmp/nsd.txt)

vpath5:::descOnly:-1:gpfsnsd01
vpath6:::dataAndMetadata:-1:gpfsnsd02
vpath7:::dataAndMetadata:-1:gpfsnsd03
vpath8:::dataAndMetadata:-1:gpfsnsd04
vpath9:::dataAndMetadata:-1:gpfsnsd05
vpath10:::dataAndMetadata:-1:gpfsnsd06
vpath11:::dataAndMetadata:-1:gpfsnsd08
vpath12:::dataAndMetadata:-1:gpfsnsd09
vpath13:::dataAndMetadata:-1:gpfsnsd10

mmcrnsd -F /tmp/nsd.txt -v yes

s) Add a tie breaker disk
mmchconfig tiebreakerDisks=gpfsnsd01

t) Start gpfs cluster
mmstartup -C cluster-name

u) create a gpfs fs
create a file named /tmp/nodes.fs.nsd

gpfsnsd02:::dataAndMetadata:-1
gpfsnsd03:::dataAndMetadata:-1
gpfsnsd04:::dataAndMetadata:-1
gpfsnsd05:::dataAndMetadata:-1
gpfsnsd06:::dataAndMetadata:-1
gpfsnsd08:::dataAndMetadata:-1
gpfsnsd09:::dataAndMetadata:-1
gpfsnsd10:::dataAndMetadata:-1

mmcrfs /new_share /dev/gpfs_dev -F /tmp/nodes.fs.nsd -B 64K -A yes
mount /new_share

v) mount on other nodes:
ssh node_name mount mount /new_share

If it is a new node in the cluster:

ssh node_name cfgmgr
mmstartup -w node_name
ssh node_name mount mount /new_share

x) - If you want to add more nodes:
mmaddnode node_name
ssh node_name cfgmgr
mmstartup -w node_name
ssh node_name mount /new_share
