访问GlusterFs

 

访问方式

1.      GlusterNative Client

2.      NFSv3 protocol

3.       CIFS

 

 ① GlusterNative Client

 

1.     安装

 

wget -P /etc/yum.repos.d 

 

# yum -y installglusterfs-fuse glusterfs

 

# modprobe fuse

# glusterfs–-version

 

2.     挂载GlusterFs

 

# mount -t glusterfsHOSTNAME-OR-IPADDRESS:/VOLNAME MOUNTDIR

 

Forexample:

# mount.glusterfs g1:/SR-volume /tmp/volume/

 

这样client就可以通过读写/tmp/volume/ 访问GlusterFs了。

 

需要自动挂载时，将下面内容写入文件 /etc/fstab中：

 

g1:/SR-volume /tmp/volume/ glusterfs defaults,_netdev 0 0

 

Mounting Options

 

backupvolfile-server=server-name

       server-name为gluster的节点名字。mount.glusterfs g1:/SR-volume /tmp/volume/ 此时如果g1宕机，则客户端无法访问glusterfs；如果使用该选项指定另外一个server-name，即：

mount.glusterfs -o backupvolfile-server=g2 g1:/SR-volume /tmp/volume/ ，如果g2是在线状态，即便g1宕机，客户端也可以访问glusterfs。可以指定多个server-name。

 

fetch-attempts=N

       尝试连接gluster server的次数，如果超过N次，则认为改节点不可用。

 

log-file=LOG-FILE

              File to use for logging[default:/var/log/glusterfs/glusterfs.log]

 

log-level=LOG-LEVEL

Logging severity. Valid options are TRACE, DEBUG, WARNING, ERROR, CRITICAL INFO and NONE[default: INFO]

ro                     Mount the filesystem read-only

 

volfile-id=KEY

              Volume key or name of the volumefile to be fetched from server

 

transport=TRANSPORT-TYPE

              Transport type to get volume filefrom server [default: tcp]

 

 

volume-name=VOLUME-NAME

Volume name to be used for MOUNT-POINT [default: topmost volume in VOLUME-FILE]

 

direct-io-mode= [enable|disable]

              Use direct I/O mode in fusekernel module

              [default: "off" if bigwrites are supported, else

              "on" for fds not openedwith O_RDONLY]

 

acl                       for enabling posix-ACLs

 

worm            making the mount WORM - Write Once, Read Manytype

 

selinux           enable selinux on GlusterFS mount

 

fopen-keep-cache

              Do not purge the cache on fileopen.

 

Forexample:

# mount.glusterfs -o ro,acl,worm,direct-io-mode=enable,fopen-keep-cacheg1:/SR-volume /tmp/volume/

 

2.1 自动挂载

 

vi /etc/fstab

===========================================================

g1:/SR-volume /tmp/volume/ glusterfs  ro,acl,defaults   0  0

===========================================================

 

 ②NFS

 

1.     安装

yum install –y rpcbind nfs-utils

 

2.     挂载GlusterFs

mount -t nfs g1:/SR-volume /tmp/volume/

 

2.1 自动挂载

 

vi /etc/fstab

===========================================================

g1:/SR-volume /tmp/volume/ nfs      defaults  0  0

===========================================================

 

 ③CIFS

   用于 Mac OS及Windonws系统；以samba服务为基础。
