问题描述

LUN在SnapLock后没有元数据：

::> lun show -instance -vserver iscsi_svm_snaplock -path /vol/snaplock_mir_SQL_data_vol/lun.dat

Vserver Name: iscsi_svm_snaplock LUN Path: /vol/snaplock_mir_SQL_data_vol/lun.dat Volume Name: snaplock_mir_SQL_data_vol Qtree Name: "" LUN Name: lun.dat LUN Size: - OS Type: - Space Reservation: - Serial Number: - Serial Number (Hex): - Comment: - Space Reservations Honored: - Space Allocation: - State: - LUN UUID: - Mapped: unmapped

卷正常，并且类型为 DP：

::> volume show -instance -vserver iscsi_svm_snaplock -volume snaplock_mir_SQL_data_vol

Vserver Name: iscsi_svm_snaplock Volume Name: snaplock_mir_SQL_data_vol Aggregate Name: cluster1_04_aggr2_sata_snaplock List of Aggregates for FlexGroup Constituents: cluster1_04_sata_snaplock Encryption Type: none List of Nodes Hosting the Volume: cluster1_04 Volume Size: 811.8GB Volume Data Set ID: 5944 Volume Master Data Set ID: 2154731386 Volume State: online Volume Style: flex Extended Volume Style: flexvol FlexCache Endpoint Type: none Is Cluster-Mode Volume: true Is Constituent Volume: false Number of Constituent Volumes: - Export Policy: default User ID: 0 Group ID: 0 Security Style: unix UNIX Permissions: ---rwxr-xr-x Junction Path: - Junction Path Source: - Junction Active: - Junction Parent Volume: - Comment: Available Size: 150.0GB Filesystem Size: 811.8GB Total User-Visible Size: 811.8GB Used Size: 661.8GB Used Percentage: 81% Volume Nearly Full Threshold Percent: 95% Volume Full Threshold Percent: 98% Maximum Autosize: 100TB Minimum Autosize: 322.5GB Autosize Grow Threshold Percentage: 85% Autosize Shrink Threshold Percentage: 70% Autosize Mode: grow_shrink Total Files (for user-visible data): 21251126 Files Used (for user-visible data): 101 Space Guarantee in Effect: true Space SLO in Effect: true Space SLO: none Space Guarantee Style: none Fractional Reserve: 0% Volume Type: DP

LUN文件包含在卷快照中：

::> set advanced

Warning: These advanced commands are potentially dangerous; use them only when directed to do so by NetApp personnel. Do you want to continue? {y|n}: y

::*> system node run -node cluster1-04 -command "ls /vol/snaplock_mir_SQL_data_vol/.snapshot/SP_2_399842_1711652461" . .. lun.dat

尝试使用还原快照时 snapmirror restore，生成的LUN也没有状态，并且无法联线以恢复数据：

::> lun online -vserver iscsi_svm -path /vol/temp_SQL_data_vol/lun.dat Error: command failed: Error while looking up LUN "/vol/temp_SQL_data_vol/lun.dat". Reason: Invalid argument.

SnapMirror关系：

::> snapmirror show -instance -source-path iscsi_svm:mir_SQL_data_vol -destination-path iscsi_svm_snaplock:snaplock_mir_SQL_data_vol

Source Path: iscsi_svm:mir_SQL_data_vol Source Cluster: - Source Vserver: iscsi_svm Source Volume: mir_SQL_data_vol Destination Path: iscsi_svm_snaplock:snaplock_mir_SQL_data_vol Destination Cluster: - Destination Vserver: iscsi_svm_snaplock Destination Volume: snaplock_mir_SQL_data_vol Relationship Type: XDP

SnapLock之前的源LUN具有预期的元数据：

::> lun show -instance -vserver iscsi_svm -path /vol/mir_SQL_data_vol/lun.dat

Vserver Name: iscsi_svm LUN Path: /vol/mir_SQL_data_vol/lun.dat Volume Name: mir_SQL_data_vol Qtree Name: "" LUN Name: lun.dat LUN Size: 500GB OS Type: windows Space Reservation: disabled Serial Number: 802Ks$Fn0v3f Serial Number (Hex): 3830324b7324466e30763366 Comment: Space Reservations Honored: false Space Allocation: disabled State: online LUN UUID: 07498d86-41c1-4d05-b87b-ac666774de10 Mapped: unmapped

仅列出源LUN，而不列出SnapLock LUN lun show：
