連線至多個檔案

貢獻者

您可以連線至多個位於磁碟區中的檔案。下列範例說明如何完成此作業。

若要建立受限的FlexClone、您必須在「snapdrive.conf」檔案中設定「shan clone-method=oponust」、或是在不受限制的情況下提供「-clone」、才能連線至多個檔案。此範例顯示您想要連線至多個檔案、例如位於Volume vol1中的snap1、mnt/fs_1和`/mnt/fs_2。

/mnt/fs_1和/mnt/fs_2的配置如下所示:

 # snapdrive storage show -fs /mnt/fs_1 /mnt/fs_2 -capabilities
raw device: /dev/sdc1   mount point: /mnt/fs_1 (persistent) fstype ufs
allowed operations: all

device filename      adapter     path     size    proto   state     clone     lun path           backing snapshot
----------------     -------     ----    ------   -----   -----    -------  ----------------     ----------------
/dev/sdc                -         P       100m    iscsi   online      No    homer:/vol/vol1/lun1        -

raw device: /dev/sdo1   mount point: /mnt/fs_2 (persistent) fstype ufs
allowed operations: all

device filename     adapter path    size     proto   state   clone    lun path               backing snapshot
----------------    ------- ----    ----    -------  -----   -----    --------               ----------------
/dev/sdo               -     P      100m     iscsi   online   No      homer:/vol/vol1/lun2        -

在此、使用者使用Snapshot snap2、其中包含應用程式一致的快照、如「/mnt/fs1」和「/mnt/fs2」、以利SnapConnect。

 # snapdrive snap connect -fs /mnt/fs_1 -fs /mnt/fs_2 -snapname homer:/vol/vol1:snap2 -autorename -clone unrestricted

 connecting /mnt/fs_1:
        creating unrestricted volume clone homer:/vol/Snapdrive_vol1_volume_clone_from_snap2_snapshot ... success

        mapping new lun(s) ... done

 connecting /mnt/fs_2:

        mapping new lun(s) ... done
        discovering new lun(s) ... done
Successfully connected to snapshot homer:/vol/vol1:snap2
        file system: /mnt/fs_1_0
        file system: /mnt/fs_2_0

在這裏SnapDrive 、UNIX版的支援已從Snapshot snap2建立單一不受限制的FlexClone「napdrive_vol1_0_volvole_clone from _snap2_Snapshot」。然後連接到LUN testlun1和testlun2、分別建立複製的主機檔案系統「/mnt/fs1_0」和「/mnt/fs2_0」。

# snapdrive storage show -fs /mnt/fs_1_0 /mnt/fs_2_0 -capabilities
raw device: /dev/sde1   mount point: /mnt/fs_1_0 (persistent) fstype ufs
allowed operations: all

----------------      -------  ----  ----    -----   -----   -----       --------                                                        ----------------
