Welcome to the Community,

from a first look at the logfile it seems as if the file is truncated by approximately a half MB.

As a first step, and to see what can be done,

• open a terminal window, and go to the VM's .vmwarevm folder
• run: ls -l > filelist.txt (to create a file listing, which contains all of the VM's files with their file names, sizes, time stamps, ...)
• run: dd if="Virtual Disk.vmdk" of="Metadata-1536.bin" bs=1536 count=1

then compress/zip filelist.txt, an Metadata-1536.bin, and attach the .zip archive to a reply post.

Based on the results, I will then provide you with another dd command, to extract all metadata (no userdata) from the .vmdk file.

Thank you!

Attached .zip archive for review.

According to the .vmdk file's header data, the metadata occupies 25.728 blocks (512 Bytes each).

Please run:

dd if="Virtual Disk.vmdk" of="Metadata-full.bin" bs=512 count=25728

to extract the metadata, then compress/zip it and attach the .zip archive to your next reply.

Please see the attachment named Metadata-full.bin.zip, Thank you!

The file contains one mismatch in its grain tables, and is ~512MB too large, i.e. none of the grains point to the additional space.

To fix this, run the following commands:

printf '\x00' | dd of="Virtual Disk.vmdk" bs=1 seek=72 count=1 conv=notrunc

printf '\x80' | dd of="Virtual Disk.vmdk" bs=1 seek=8114408 count=1 conv=notrunc
printf '\x2B' | dd of="Virtual Disk.vmdk" bs=1 seek=8114409 count=1 conv=notrunc
printf '\xF1' | dd of="Virtual Disk.vmdk" bs=1 seek=8114410 count=1 conv=notrunc
printf '\x01' | dd of="Virtual Disk.vmdk" bs=1 seek=8114411 count=1 conv=notrunc

dd if=/dev/null of="Virtual Disk.vmdk" bs=1 seek=23543873536 count=1

Line 1 will reset the "uncleanShutdown" flag
Lines 2-5 will fix the grain table mismatch
Line 6 will truncate the .vmdk file to the expected size

Since the root cause of this corruption isn't known, I strongly recommend that you backup the .vmdk file before making the modifications. There's also a chance of file system corruption within the guest OS.
