其中上半部分展示的是Dbspaces 數據庫表空間信息。

number為表空間唯一標示號

pagesize數據庫空間的頁大小

flag?列信息：

Position?1:M鏡像

N未鏡像

Position?2:X新鏡像

DDown，不可用chunk

P物理恢復完成，等待邏輯恢復

L正在邏輯恢復

R正在恢復

Position?3:BBLOB空間

P物理日志空間

S智能大對象空間

T臨時空間

U臨時智能大對象空間

WSDS主節點的臨時空間，只在SDS備節點顯示

Position?4:B空間可包含大于2G的chunk

Position?5:A空間自動擴展

下半部分展示的上Chuncks信息，通過chunk/dbs列展示的chunk號/表空間號來對應chunk所屬表空間，及chunk文件的物理位置

flags

Position?1:P主chunk

M鏡像chunk

Position?2:O可用

D不可用

I不一致狀態，高可用環境下備機顯示該狀態

R正在恢復

X新鏡像chunk

N重命名chunk

Position?3:-標準數據空間

BBLOB空間

S智能大對象空間

Position?4:B大于2G的chunk

Position?5:E可擴展chunk

-不可擴展chunk

Position?6:-文件chunk未開啟直接I/O或同步I/O
