I. Node preparation

1. Node configuration

hostname

g0

matada node

g1

matadata node g2

matadata node g3

data node

g4

data node g5

data node

2. Install ntp

yum install ntp -yservice ntpd startsystemctl enable ntpd

Second, install gpfs

1. Set ssh to login without password

salt-ssh -i '*' cp.get_file salt://id_rsa /root/.ssh/id_rsasalt-ssh -i '*' cp.get_file salt://id_rsa.pub /root/.ssh/id_rsa.pubsalt-ssh -i '*' cmd.run 'chmod 600 /root/.ssh/id_rsa'salt-ssh -i '*' cmd.run 'chmod 600 /root/.ssh/id_rsa.pub'

2. Install gpfs

salt-ssh -i 'g*' cmd.run 'cd /root/gpfs && tar xvzf GPFS_4.1_ADV_LSX.tar.gz'salt-ssh -i 'g*' cmd.run 'cd /root/gpfs/gpfs_install-4.1.0-0_x86_64 --silent'salt-ssh -i 'g*' cmd.run 'yum localinstall /usr/lpp/mmfs/4.1/*rpm -y'salt-ssh -i 'g*' cmd.run 'bash /root/gpfs/Spectrum_Scale_Advanced-4.1.1.3-x86_64-Linux-update'salt-ssh -i 'g*' cmd.run 'mv /usr/lpp/mmfs/4.1.1.3/gpfs.hadoop-connector-2.7.0-2.x86_64.rpm /usr/lpp/mmfs/4.1.1.3/gpfs.hadoop-connector-2.7.0-2.x86_64.rpm.orig'salt-ssh -i 'g*' cmd.run 'yum localinstall /usr/lpp/mmfs/4.1.1.3/*rpm -y'

Compile the gpfs kernel module and execute it on one of the nodes

3.1 Compile kernel module

cd /usr/lpp/mmfs/src/yum install kernel-devel cpp gcc gcc-c++make LINUX_DISTRIBUTION=REDHAT_AS_LINUX Autoconfigmake Worldmake InstallImages

3.2 Compile the gpfs kernel module into an rpm package

yum install rpm-buildmake rpm

3.3 Copy the compiled rpm package to other nodes and install it.

4. Set path variable

salt-ssh -i 'g*' file.append /etc/profile 'export PATH=$PATH:/usr/lpp/mmfs/bin/'

Create a gpfs cluster

1. Create a gpfs node

Edit the profile used to create the node

cat /root/gpfs_config/nodefileg0:quorum-managerg1:quorum-managerg2:quorum-managerg3:managerg4:managerg5:managerEOF

Create a gpfs cluster

mmcrcluster -N /root/gpfs_config/nodefile -p g0 -s g1 -C gpfscluster -A -r /usr/bin/ssh -R /usr/bin/scp Parameters: -N indicates the node's configuration file-p indicates the primary node-s indicates the Secondary cluster configuration server-C cluster name-A indicates that the GPFS daemon does not shut down when a node restarts. - R and-R are communication protocols.

2. Authorized license

mmchlicense server --accept -N g0,g1,g2,g3,g4,g5

3. Add NSD

Edit nsdfile.cfg

%pool: pool=system blockSize=512K layoutMap=cluster%pool: pool=datapool blockSize=2M layoutMap=cluster writeAffinityDepth=1 blockGroupFactor=256%nsd: device=/dev/vdb servers=g0 nsd=metansd00 usage=metadataOnly pool=system%nsd: device=/dev/vdb servers=g1 nsd=metansd01 usage=metadataOnly pool=system%nsd: device=/dev/vdb servers=g2 nsd=metansd02 usage=metadataOnly pool=system %nsd: device=/dev/vdb servers=g3 nsd=datansd00 usage=dataOnly pool=datapool%nsd: device=/dev/vdb servers=g4 nsd=datansd01 usage=dataOnly pool=datapool%nsd: device=/dev/vdb servers=g5 nsd=datansd02 usage=dataOnly pool=datapool

Add NSD

mmcrnsd -F nsdfile.cfg

4. Start the cluster

mmstartup -a#View cluster status: mmgetstate -La

5. Create a gpfs file system

# mmcrfs /gpfs gpfs -F nsdfile.cfg -A yes -v nommcrfs gpfs -F nsdfile.cfg -A yes -B 1M -j hcluster -m 2 -r 2 -M 3 -R 3 -T /gpfs --metadata-block-size 256K-v no Parameters: gpfs: Denotes the name of the file system-F: Specifies the NSD configuration file-A: Set this item to yes-B: Specifies the size of the data block, which must be 16k, 64k, 128k, 256k, 512k, 1M, 2M, 4M, 8M, 16M.- j: Specify mapping type-m: Default value for number of metadata copies-M: Maximum value for number of metadata copies-r: Default value for number of data copies-R: Maximum value for number of data copies-T: Mount point--metadata-block-size: Size of metadata node block-v Verify that the disk created already has a file system Yes No mmshutdown -ammchconfig maxblocksize=2048Kmmstartup -ammcrfs gpfs -F nsdfile.cfg -A yes -j hcluster -m 2 -r 2 -M 3 -R 3 -T /gpfs -v no

6. Mount the file system

mmmount gpfs /gpfs -N all
