        One major advantage of ddrescue is the option to restart a copy-process.
        So if you keep the outputfile and the copy-log you can abort at any time.
        Then reconfigure your network and restart with the same command.

          Ddrescue finished today.

           

          2018-08-30_19-31-55.png

           

          There are no read errors, etc..

           

          The strange thing is that it had 3h remaining time and suddenly finished on 94,22%. What does it mean - that it was not able to rescue all?

           

           

          It does not seems to be complete.

           

          Here is the output from its log file:

          # Mapfile. Created by GNU ddrescue version 1.22

          # Command line: ddrescue /vmfs-in/Flawless Server/Flawless Server-flat.vmdk /vmfs-out/Flawless Server/Flawless Server-flat.vmdk /vmfs-out/Flawless Server/copy1.log

          # Start time:   2018-08-30 19:31:48

          # Current time: 2018-08-30 19:31:51

          # Finished

          # current_pos  current_status  current_pass

          0x1B495790000     +               1

          #      pos        size  status

          0x00000000  0x1B495790000  +

           

          Regardless to this I have moved the remaining portion of files, renamed the previous folder (old datastore) and registered the VM.


          The problem I face now is that it refuses to start and requires me to connect another vmdk on another hard drive (another data store):

          Cannot open the disk '/vmfs/volumes/5b81bebc-162ed5e6-79ce-6805ca128dcc/Flawless Server/Flawless Server.vmdk' or one of the snapshot disks it depends on.

           

          I have not moved the other volume anywhere and its still present with the same name, so that is why I do not get what is wrong and what needs to be done to fix it.

            Here is the vmware log file:

            https://paste.ee/p/1aRhm

             

            018-08-30T17:51:16.521Z| vmx| I125+ Power on failure messages: The file specified is not a virtual disk

            I have removed the second hard drive from the VM settings and added it again. The problem still persists.

              The important part in the log file is:

              2018-08-30T17:51:16.501Z| worker-2115541| I125: DISKLIB-VMFS  : VmfsExtentCommonOpen: possible extent truncation (?) realSize is 3662331008, size in descriptor 3886945402.

              2018-08-30T17:51:16.501Z| worker-2115541| I125: DISKLIB-VMFS  : "/vmfs/volumes/5b81bebc-162ed5e6-79ce-6805ca128dcc/Flawless Server/Flawless Server-flat.vmdk" : failed to open (The file specified is not a virtual disk): Size of extent in descriptor file larger than real size. Type 3

              So it seems that the copy job didn't complete, and 224,614,394 blocks (approximately 112 GB) are missing.

                When I have tried to run the command again it reported "finished".

                 

                As mentioned above I also do not think that it is complete. I have decided to give up on ESXi and ddrescue, started the VM from the old datastore and will soon make a switch to another virtual and manually copy the data (rsync or cp).

                  Before you really decide to give up I would like to have a closer look.
