每个chain 会分配replica 数量的target，从这个图可以看出，部分target 是不可用的，先检查下所有storage服务是否正常

Similar problem. Nodes show CONNECTED via "list-nodes", but all chains remain UNAVAILABLE - How to diagnose storage servers?
我按照3FS Setup Guide配置，4节点，所以第7步改了参数, num_nodes, num_disks_per_node, node_id_end。
这是我生成chain table的命令。

python 3FS/deploy/data_placement/src/model/data_placement.py \
   -ql -relax -type CR --num_nodes 4 --replication_factor 3 --min_targets_per_disk 6
python 3FS/deploy/data_placement/src/setup/gen_chain_table.py \
   --chain_table_type CR --node_id_begin 10001 --node_id_end 10004 \
   --num_disks_per_node 1 --num_targets_per_disk 6 \
   --target_id_prefix 1 --chain_id_prefix 9 \
   --incidence_matrix_path output/DataPlacementModel-v_4-b_8-r_6-k_3-λ_2-lb_2-ub_2/incidence_matrix.pickle

mgmtd_main-err.log, storage_main-err.log里没有错误日志，请问应该怎么检查服务是否正常呢。
