kaldi NFS/GlusterFS

NFS

詳細介紹參考《鳥哥的LINUX私房菜-服務器架設篇》第十三章
主要流程

server端配置

1. 安裝兩個軟件：rpcbind和nfs-utils
2. 配置/etc/exports

<DIR> *(rw,no_root_squash)

1. 啓動nfs

/etc/init.d/rpcbind start
/etc/init.d/nfs start
/etc/init.d/nfslock start
chkconfig rpcbind on
chkconfig nfs on
chkconfig nfslock on

1. 如果更新了/etc/exports文件，需要重新掛載

exportfs -arv

client端配置

1. 安裝兩個軟件：rpcbind和nfs-utils
2. 啓動相關服務

/etc/init.d/rpcbind start
/etc/init.d/nfslock start

1. 查看服務器提供了哪些共享目錄

showmount -e hostname

1. 建立掛載點並且掛載

mkdir -p <DIR>
mount -t nfs hostname:<DIR> <DIR>
umount <DIR> #卸載

glusterfs

官方文檔：http://gluster.readthedocs.io/en/latest/

Brick：對應一臺服務器上面的存儲空間
Volume：多個brick組成一個volume，對應於多臺服務器組成的存儲空間
Trusted Storage Pool：多臺服務器組成的服務器集羣

CENTOS安裝

https://wiki.centos.org/SpecialInterestGroup/Storage/gluster-Quickstart
http://gluster.readthedocs.io/en/latest/Quick-Start-Guide/Quickstart/
安裝到以下機器：hpc191、hpc192

#1.install on hpc191/hpc192
yum install centos-release-gluster
yum --enablerepo=centos-gluster*-test install glusterfs-server
service glusterd start
service glusterd status

#2.Configure the trusted pool
gluster peer probe hpc192 #on hpc191
gluster peer probe hpc191 #on hpc192

#3.Set up a GlusterFS volume
mkdir -p /euler/glusterfs/gv1 #on hpc191/hpc192
gluster volume create gv1 hpc191:<DIR>/gv1 hpc192:<DIR>/gv1 #on hpc191
gluster volume start gv1 #on hpc191
gluster volume info #on hpc191

#4.mount
mount -t glusterfs hpc191:/gv1 /glfs #on hpc191
mount -t glusterfs hpc192:/gv1 /glfs #on hpc192

擴展節點

新增加hpc193

#1.在client安裝
yum install centos-release-gluster
yum --enablerepo=centos-gluster*-test install glusterfs-server
service glusterd start
service glusterd status

#2.Configure the trusted pool,在hpc191或者hpc192執行
gluster peer probe hpc193

#3.add brick to volume
gluster volume add-brick gv1 hpc193:<DIR>/gv1
gluster volume status

#4.mount 
mount -t glusterfs hpc193:/gv1 /glfs

#5.rebalance：add/delete brick 以後都需要rebalance
gluster volume rebalance gv1 fix-layout start #第一種方式：不遷移已有的數據
gluster volume rebalance gv1 start            #第二種方式：遷移已有的數據

卸載

#hpc191
gluster volume stop gv1 
gluster volume delete gv1
gluster peer detach hpc192
gluster peer detach hpc193

#hpc191/hpc192/hpc193
service glusferfsd stop
