Fastdfs status issues with Storage server

There are typically seven STORAGE server states:
# Fdfs_storage_status:init: Initialization, not yet available source server for synchronizing existing data

# Fdfs_storage_status:wait_sync: Waiting for synchronization, the source server has been synchronized with the existing data

# fdfs_storage_status:syncing: In sync

# fdfs_storage_status:deleted: Deleted, the server is removed from this group

# Fdfs_storage_status:offline: Offline

# Fdfs_storage_status:online: Online, no service available

# fdfs_storage_status:active: Online, can provide service


The normal state must be active if you run the following command:
Fdfs_monitor/etc/fdfs/client.conf

Servers that have the following status are found:
Storage 4:
IP_ADDR = 10.120.151.114 Wait_sync

After a variety of reboots do not solve the problem, we have to delete, and then join
# Removed from the cluster
fdfs_monitor/etc/fdfs/client.conf Delete group1 10.120.151.114

# in 114 server, delete data folder
Rm-rf/home/storage1/fastdfs/data

# Restart 114 node
Fdfs_storaged/etc/fdfs/storage.conf

Re-check Status
Fdfs_monitor/etc/fdfs/client.conf

The state becomes normal.
