我在独立模式下运行一个动物园管理员实例又称IA,试图升级到仲裁模式,然后我准备了另外2个带有空快照目录的动物园管理员实例(IB和IC),首先在3个实例中正确修改了zoo.cfg,分别创建了myid,首先重启独立实例IA,然后启动另一个实例。
IB和IC发生了什么,他们有数据,但根目录不存在:
IB和IC:
[zk: localhost:2181(CONNECTED) 14] ls /
Node does not exist: /
[zk: localhost:2181(CONNECTED) 15] ls /zookeeper
[quota]
[zk: localhost:2181(CONNECTED) 16]
此外,IB中存在数据丢失:
[zk: localhost:2181(CONNECTED) 16] get /demo/version
cZxid = 0x30000006c
ctime = Thu Dec 22 17:49:13 CST 2016
mZxid = 0x30000006c
mtime = Thu Dec 22 17:49:13 CST 2016
pZxid = 0x6003792a0
cversion = 12764622
dataVersion = 0
aclVersion = 0
ephemeralOwner = 0x0
dataLength = 0
numChildren = 135794
[zk: localhost:2181(CONNECTED) 17]
IA看起来像:
[zk: localhost:2181(CONNECTED) 10] get /demo/version
cZxid = 0x30000006c
ctime = Thu Dec 22 17:49:13 CST 2016
mZxid = 0x30000006c
mtime = Thu Dec 22 17:49:13 CST 2016
pZxid = 0x6003792a0
cversion = 12312921
dataVersion = 0
aclVersion = 0
ephemeralOwner = 0x0
dataLength = 0
numChildren = 587495
[zk: localhost:2181(CONNECTED) 11]
IC看起来像:
[zk: localhost:2181(CONNECTED) 10] get /demo/version
cZxid = 0x30000006c
ctime = Thu Dec 22 17:49:13 CST 2016
mZxid = 0x30000006c
mtime = Thu Dec 22 17:49:13 CST 2016
pZxid = 0x6003792a0
cversion = 12312921
dataVersion = 0
aclVersion = 0
ephemeralOwner = 0x0
dataLength = 0
numChildren = 587495
[zk: localhost:2181(CONNECTED) 11]
不过,状态还不错:
IA:
[shell@kernel /data/zookeeper/zookeeper-3.4.8/bin]# ./zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /data/zookeeper/zookeeper-3.4.8/bin/../conf/zoo.cfg
Mode: follower
IB:
[shell@kernel /data/zookeeper/zookeeper-3.4.8/bin]# ./zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /data/zookeeper/zookeeper-3.4.8/bin/../conf/zoo.cfg
Mode: follower
IC:
[shell@kernel /data/zookeeper/zookeeper-3.4.8/bin]# ./zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /data/zookeeper/zookeeper-3.4.8/bin/../conf/zoo.cfg
Mode: leader
如上所示,版本是
3.4.8
提前谢谢
答案 0 :(得分:0)
我设法通过将initLimit
和syncLimit
分别更改为100
和50
来解决此问题,将tickTime
保留为2000
,然后从独立模式迁移到仲裁模式,等一下,一切都很顺利。
