    VMDK move aborted by power loss - flat file and vmdk lost - large delta files remain

    entirenet Novice

      Hello forum,

       

      i had bad luck trying to move a VM on an old ESXi 5.5 to a NFS Storage to consolidate the VMs to another server.

       

      While i was working on the cables i accidently powered off the VM host. The "move" process was disrupted. I thought no problem - the files remain on the datasore1 as long as the file was not copied by 100%. Seems it got removed from datastore even when it was not moved by 100% to the NFS storage.

       

      Of course i would not write here if i had a backup... shame on me.

       

      Well i did some repair attempt on my own but it did not work out well.

       

      What i have is a 21 GB flat.vmdk file which i copied back from NFS storage to the VMware host. The VM had originally a 250 GB provisioned harddisk. Now vSphere tells me it is thick provisioned eager zeroed.

       

      Before i tried to move the vm folder i made a snapshot but it seems on try and error i removed the snapshot in the vSphere client - tho i still have 3 delta files, one which is quiet old and big with 54 GB in size. So maybe there is a chance to get a flat file restored out of all 3 delta files? If so, what are the steps?

       

      Thanks in advance.

       

      Regards.

          To get an overview, please post a complete list of files in the VM's folder, i.e. the output of ls -lisa from the command line.

          If there are still some vmware.log files from the time when the VM was still healthy, please attach them to a reply post.

            1. Identify the size of the flat file in bytes. 
            2. Create a new blank virtual disk that is the same size as the original. This serves as a baseline example that is modified in later steps.
            3. Rename the descriptor file (also referred to as a header file) of the newly-created disk to match the name of the original virtual disk. 
            4. Modify the contents of the renamed descriptor file to reference the flat file. 
            5. Remove the leftover temporary flat file of the newly-created disk, as it is not required.

              Unfortunately the logs have been overwritten with all of my own attempts to repair / restore the disk descriptor and flat file while firing up the VM again. My bad - should have made a fulll backup before playing around. *sigh*

                Thank you Buddhlka01 and Himadri.

                 

                I tried that but the VM was not booting. Tho as it was controller type pvscsi originally, i will try now to do it as lsilogic controller type.

                 

                Well, was not booting is not correct at all - the VM did boot but the Linux bootloader Grub only reported "grub-rescue: error: out of disk." and it seems the MBR and partition table and so on seems missing - which is no wonder as the flat file i copied back from NFS storage is broken.

                 

                My hope is that with the delta files some data can be recovered even if the whole disk can't be restored.

                 

                Regards,

                  Hint: You may use e.g. WinSCP to download these files from the datasatore.

                   

                  Am I right in assuming that you've only created/modified the "Nuvola Cloud VPS.vmdk" so far?

                    Hi a.p. ,

                     

                    you are right, i recreated Nuvola Cloud VPS.vmdk as that file was missing along with the .flat file.

                     

                    But guess what. I only used the vSphere datastore browser to retain the .flat file from the NFS Storage. Now i found via WinSCP there ist the original "Nuvola Cloud VPS.vmdk" left on the NFS folder. Thats the content:

                     

                    # Disk DescriptorFile

                    version=1

                    encoding="UTF-8"

                    CID=7b450b10

                    parentCID=ffffffff

                    isNativeSnapshot="no"

                    createType="vmfs"

                     

                    # Extent description

                    RW 524288000 VMFS "Nuvola Cloud VPS-flat.vmdk"

                     

                    # The Disk Data Base

                    #DDB

                     

                    ddb.virtualHWVersion = "8"

                    ddb.longContentID = "80a8fb400cbdcb5686a385397b450b10"

                    ddb.uuid = "60 00 C2 92 60 a3 ff bb-c9 c0 78 31 87 e0 6b 77"

                    ddb.geometry.cylinders = "32635"

                    ddb.geometry.heads = "255"

                    ddb.geometry.sectors = "63"

                    ddb.adapterType = "lsilogic"

                    ddb.toolsVersion = "9221"

                     

                    Maybe that original disk descriptor helps us.

                     

                    I attached the requested files in a zip file.

                     

                    Thank you sofar for the support.

                      What should work is to copy the original .vmdk file over to the VM's folder (i.e. overwrite the manually created one), and also edit the configuration (.vmx) file!!!

                      It looks like you've tried to attach the virtual disk from the GUI, which added the base disk instead of the current snapshot.

                      Please change the virtual disk's file name in the .vmx file to:

                      scsi0:0.fileName = "Nuvola Cloud VPS-000003.vmdk"

                      then reload the VM, to make the host aware of the change. Follow steps 2 and 3 from https://kb.vmware.com/kb/1026043

                       

                      Once done, I'd recommend that you create a new, temporary snapshot before you power on the VM. This way the current .vmdk files won't get modified, and you'll have a way back in case it's necessary.

                        Okay, i copied the original saved .vmdk into the vm folder and did overwrite the one i created.

                         

                        I edited the vmx and change the file nam,e to the 00003.vmdk and reloaded the vm using vim-cmd.

                        THen i created an offline snapshot and fired up the vm after that.

                         

                        Now i get the error message:

                         

                        "Cannot open the disk '/vmfs/volumes/53daa82a-ce8997b8-ddd9-0015c5f16c2c/Nuvola_Cloud_VPS/Nuvola Cloud VPS-000004.vmdk' or one of the snapshot disks it depends on.

                        I checked wether the disk chain is consitent and get:

                        So, i guess the whole chain backwards is fine - just the reference from 000001.vmdk to the broken/truncated flat file is the issue - right?

                          I'm afraid you're right regarding the flat file corruption.

                          Rather than trying other things which may make things worse, try to contact continuum. He's a specialist when it comes to data recovery. Maybe he can extract missing data from the VMFS volume.

                            From what i understand is that a process is locking the 1st delta file so the chain is inconsitent. How can i fix that to try a bit more?

                              After a reboot of the server the chain is now clean/consisten - tho the VM boots but the bootloader is not able to start the Linux system as it is missing files.

                                Since the base/flat disk seems to be incomplete (250GB provisioned, ~21GB remaining), I'd think the best you can do is to boot the VM from a Live Linux ISO image, and try to extract/backup important data. Attempts to reinstall, or fix the guest OS may overwrite data. However, since you've created a new snapshot, you can basically try different things, and revert to that snapshot if needed.

                                  Currently i have created a new flat file with the exact 250 GB and placed it into the delta chain. I was able to boot with a live linux iso and currently a sh*t ton of unattached inodes are processed by fsk and i assume tons of files are going to be dumped into the lost and found folder. Ah, yes - prior testdisk tool from GPartes Live iso repaired the partition table and other stuff.

                                   

                                  Since i run here with an empty / blank flat file and the deltas, i expect to miss a lot of files.

                                   

                                  I wonder if i should run the same procedurte with that "rescued" 21 GB truncated flat file. Not sure if i can do something like linux dd to copy the content of my 21 GB file into/over that newly created 250 Gb flat file. Would that work?
