Function Documentation

PVFS_error PVFS_mgmt_count_servers (  PVFS_fs_id  fs_id, PVFS_credentials *  credentials, int  server_type, int *  count )

Counts the number of servers of a given type present in a file system. Parameters: count  pointer to address where output count is stored Returns: 0 on success, -PVFS_error on failure.

PVFS_error PVFS_mgmt_get_server_array (  PVFS_fs_id  fs_id, PVFS_credentials *  credentials, int  server_type, PVFS_BMI_addr_t *  addr_array, int *  inout_count_p )

Obtains a list of all servers of a given type in a specific file system. Returns: 0 on success, -PVFS_error on failure.

const char* PVFS_mgmt_map_addr (  PVFS_fs_id  fs_id, PVFS_credentials *  credentials, PVFS_BMI_addr_t  addr, int *  server_type )

Maps a given opaque server address back to a string address. Also fills in server type. Returns: Pointer to string on success, NULL on failure.

PVFS_error PVFS_mgmt_setparam_all (  PVFS_fs_id  fs_id, PVFS_credentials *  credentials, enum PVFS_server_param  param, struct PVFS_mgmt_setparam_value *  value, PVFS_error_details *  details, PVFS_hint  hints )

Set a single run-time parameter on all servers in a given file system. Returns: 0 on success, -PVFS_error on failure.

PVFS_error PVFS_mgmt_setparam_single (  PVFS_fs_id  fs_id, PVFS_credentials *  credentials, enum PVFS_server_param  param, struct PVFS_mgmt_setparam_value *  value, char *  server_addr_str, PVFS_error_details *  details, PVFS_hint  hints )

Sets a single run-time parameter on a specific server.

Here is the call graph for this function:

PVFS_error PVFS_mgmt_statfs_all (  PVFS_fs_id  fs_id, PVFS_credentials *  credentials, struct PVFS_mgmt_server_stat *  stat_array, int *  inout_count_p, PVFS_error_details *  details, PVFS_hint  hints )

Obtains file system statistics from all servers in a given file system. Returns: 0 on success, -PVFS_error on failure.
