HCIA-Cloud Computing V4.0 Lab Guide

Question: After a VM is restored using a snapshot, will a snapshot created after the snapshot be affected? 

Step 12  After the VM is restored using the snapshot, run the df –Th command to check the disk attachment status on the Linux_01 VM.

The preceding information indicates that  /dev/vd  /dev/vdb1 b1  and  /dev/vdc1  are detached after the restoration.

Step 13  Log in to the Linux_02 VM as the root user by referring to Step to  Step 8. Run 8. Run the following command to change the content of the test file test3.file under  /tmp/Test3  /tmp/T est3 from this this is test test file to this is new file:

Step 14  Restore the Linux_02 VM using snapshot Snap_01. For details, see Step see  Step 10.  10.  Step 15  After the restoration, check the disk attachment status of the Linux_02 VM.

 

 

HCIA-Cloud Computing V4.0 Lab Guide

If the preceding information is displayed,  /dev/vdc1  is also detached after the restoration

Conclusion: After restoration, the disk Disk_02 (slave), disk Disk_01 (independent & persistent), and disk Disk_02 (independent & nonpersistent) are detached.

Step 16  Run the mount command to attach attac h the Disk_01 disk to the Linux_ Linux_01 01 VM and check whether the modified file exists in the /tmp/Test1 directory. mount /dev/vdb1 /tmp/Test1 cd /tmp/Test1 ll cat test1.file

If the preceding information is displayed, the modified file still exists in Disk_01  (independent & persistent) after the restoration. Data changes are immediately written to the disk.

Step 17  Run the following command to attach Disk_03 to Linux_02. mount /dev/vdc1 /tmp/Test3

The system displays a message indicating that  /dev/vdc1 does not exist and cannot be attached again. After the restoration, the disk Disk_03  (independent & nonpersistent) needs to be attached and formatted again, and the data in the disk will be lost.

Summary:  When a VM snapshot is created, snapshots are not created for Disk_01  (independent & persistent) or Disk_03 (independent & nonpersistent), and disk data cannot be restored. After the VM restoration, Disk_01 is detached, and after af ter the VM is

 

 

HCIA-Cloud Computing V4.0 Lab Guide

attached again, its data is not lost. Disk_03 (independent & nonpersistent n onpersistent)) is detached and cannot be attached again. In addition, the disk needs to be attached and formatted again, and data in the disk will be lost.

Step 18  After the preceding steps are performed, migrate Linux_01 to the original host CNA01 and detach the shared disk Disk_01 from Linux_01 and Linux_02. In the VM disk list, locate the row that contains the target disk, and click Detach. In the dialog box that is displayed, click Confirm.
