[Resolved] Supposedly "dynamic" vmdk file does not resize.

[socratis]

I'll try it here with a test-clone and see what's going on...

And I did. Win7-32, initial 80 GB, resized to 100 GB:

Option 1: Native
Run your Win7 VM, go to Administrative tools » Computer Management » Disk Management. I have a 100 "System Partition", a 79.90 GB "C:\" partition, and a 20 GB unallocated space. Right-click on the "C:\" partition » Extend Volume... » the default remaining 20480 comes up as pre-selected. Finish the wizard, my "C:\" partition became 99.90 GB. As expected...

Option 2: GParted
Upon starting GParted (gparted-live-0.28.1-1-i686.iso) shows the following partitions:

[quote]Partition      File System    Label              Size          Used         Unused       Flags
/dev/sda1      ntfs           System Reserved    100.00 MiB    24.36 MiB    75.64 MiB    boot
/dev/sda2      ntfs                               79.90 GiB    14.59 GiB    65.31 GiB
unallocated    unallocated                        20.00 GiB           --           --
[/quote]

Right-click on /dev/sda2 » Resize/Move » drag till the end, until you have:

• Free space preceding (MiB): 0,
• New size (MiB): 102299,
• Free space following (MiB): 0.

Hit "Resize/Move", "Apply", "Apply", done. After that, this is what you get:

[quote]Partition      File System    Label              Size          Used         Unused       Flags
/dev/sda1      ntfs           System Reserved    100.00 MiB    24.36 MiB    75.64 MiB    boot
/dev/sda2      ntfs                               99.90 GiB    14.59 GiB    85.31 GiB

I don't really like the message that your "ntfs-3g" is not loaded. No kidding it can't read your NTFS partition, that part is missing, I don't know why. What did you download? From where?

I'll be damned. "Disk Management" worked. When I tried it yesterday, I couldn't even see the extra 30GB. Now the thing is enlarged, as I wanted.

Don't know what happened but it's good now.

Glad you got it going finally...
