gluster副本三配置down两个可写

需求

默认做了控制，副本三down两个就阻止写了，这个可以通过参数控制

参数调整

副本三，关闭两个可写

gluster volume set testvolume cluster.quorum-type fixed
gluster volume set testvolume cluster.quorum-count 1
gluster volume set testvolume cluster.quorum-reads yes
gluster volume set  testvolume network.ping-timeout 10

副本二，关闭一个可写

gluster volume set testvolume cluster.quorum-count 1
gluster volume set testvolume cluster.quorum-reads yes
gluster volume set  testvolume network.ping-timeout 10

上面的区别是，副本3默认把cluster.quorum-type设置为auto了
