glusterfs分布式文件系统用作文件同步安装配置

rpm包安装

官方站点：http://download.gluster.org/pub/gluster/glusterfs/
yum install centos-release-gluster

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

# mkfs.xfs -i size=512 /dev/sdb1

# mkdir -p /bricks/brick1

# vi /etc/fstab

/dev/sdb1 /bricks/brick1 xfs defaults 1 2

# mount -a && mount

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

yum install xfsprogs

yum --enablerepo=centos-gluster*-test install glusterfs-server

service glusterd start

gluster peer probe gv02

gluster peer status 

mkdir /data/repository

gluster volume create gv0 replica 2 gv01:/data/repository gv02:/data/repository

gluster volume start gv0

gluster volume info

mount -t glusterfs gv01:/gv0 /mnt

mount -t glusterfs gv02:/gv0 /mnt

for i in `seq -w 1 100`; do cp -rp /var/log/messages /mnt/copy-test-$i; done

查看同步情况

ls -lA /mnt | wc -l

ls -lA

创建卷时报错 volume create: gv0: failed: /data/gv0/brick1 or a prefix of it is already part of a volume

A：之前创建卷时，报错，

volume create: gv0: failed

因此，有信息遗留，需要清理。

# cd /data/gv0/brick1

# attr -lq .

glusterfs.volume-id

# setfattr -x trusted.glusterfs.volume-id .

 

或者批量：

# cd /data/gv0

# for i in `ls .`; do setfattr -x trusted.glusterfs.volume-id $i; done
