連線至多個檔案

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 jfs2 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 jfs2 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 jfs2 allowed operations: all device filename adapter path size proto state clone lun path backing snapshot ---------------- ------- ---- ---- ----- ----- ----- -------- ---------------- /dev/sde - P 100m iscsi online flex-clone homer:/vol/Snapdrive_vol1_volume_clone_from_snap2_snapshot/lun1 vol1:snap2 raw device: /dev/sdac1 mount point: /mnt/fs_2_0 (persistent) fstype jfs2 allowed operations: all device filename adapter path size proto state clone lun path backing snapshot ---------------- ------- ---- ---- ----- ----- ----- -------- ---------------- /dev/sdac - P 100m iscsi online flex-clone homer:/vol/Snapdrive_vol1_volume_clone_from_snap2_snapshot/lun2 vol1:snap2
