删除一个storage组

jcrunner

fastdfs 如何删除一个storage 组，网上找都是删除组里的一个storage

1. fdfs_monitor /etc/fdfs/client.conf delete storegroup1 192.168.1.202

复制代码

我的storagegroup1组内只有一个storage, 删除storage提示成功了，现在该删除组了

1. fdfs_monitor /etc/fdfs/client.conf delete storegroup1

复制代码

但是当我删除组时，提示

1. [2017-06-30 20:08:36] ERROR - file: tracker_proto.c, line: 48, server: 192.168.1.201:22122, response status 16 != 0
   
2. [2017-06-30 20:08:36] ERROR - file: ../client/tracker_client.c, line: 1334, fdfs_recv_response fail, result: 16
   
3. delete group: storegroup1 fail, error no: 16, error info: Device or resource busy

复制代码

查了一下tracker的代码是

1. int tracker_mem_delete_group(const char *group_name)
   
2. {
   
3.     FDFSGroupInfo *pGroup;
   
4.     int result;
   
5. 
   
6.     pGroup = tracker_mem_get_group(group_name);
   
7. 
   
8.     pGroup = tracker_mem_get_group(group_name);
   
9.     if (pGroup == NULL)
   
10.     {
    
11.         return ENOENT;
    
12.     }
    
13. 
    
14.     if (pGroup->count != 0)
    
15.     {
    
16.         return EBUSY;
    
17.     }
    
18. 
    
19.         pthread_mutex_lock(&mem_thread_lock);
    
20.     if (pGroup->count != 0)
    
21.     {
    
22.         result = EBUSY;
    
23.     }
    
24.     else
    
25.     {
    
26.     result = tracker_mem_remove_group(g_groups.groups, pGroup);
    
27.     if (result == 0)
    
28.     {
    
29.         result = tracker_mem_remove_group(g_groups.sorted_groups, pGroup);
    
30.     }
    
31.     }

复制代码

pGroup->count != 0   pGroup->count 还是等于1，所以直接返回了EBUSY
这个count 是组内stoage的个数，那我要怎么删除组？？
跪求啊 求大牛啊

fdfs_monitor /etc/fdfs/client.conf delete storegroup1 192.168.1.202这个命令有storage_id参数,

所以调用的是tracker_mem_delete_storage.

5.10的代码里:

    if (pStorageServer->status == FDFS_STORAGE_STATUS_ONLINE || \
        pStorageServer->status == FDFS_STORAGE_STATUS_ACTIVE || \
        pStorageServer->status == FDFS_STORAGE_STATUS_RECOVERY)
    {
        return EBUSY;
    }

所以删除之前需要把这个storegroup1 192.168.1.202置为以上三种之外的状态, 例如可以把192.168.1.202的storage停掉, 让状态变为OFFLINE后即可执行删除.
