【AIX 學習】檔案系統--監視

/etc/filesystems 存放這許多檔案系統的所有資訊，許多元護檔案系統的指令都是從這個檔案中擷取的檔案系統的預設屬性。此檔案的格式是stanza 格式的。包含檔案系統的名字和屬性。

        dev             = /dev/hd4   --檔案對應的邏輯裝置，邏輯卷

                                        2 true  用mount all 指令安裝，用unmount all 解除安裝檔案，系統初始化時自動執行  mount all。

                                        3 false 檔案系統不會自動安裝，必須手動安裝(用mount 指令單獨安裝)

                                        4 readonly 檔案系統以隻讀的方式安裝
