ESXi - change to thin - virtual disk filesize is the same
- by sven
running ESXi 5.5 here with a datastore on a single SSD. Now, I thought about changing to thin disks from thick and found that I could use a tool on the ESXi host to do that. However, the file size of the new created virtual disk is not changing. I run:
vmkfstools -i loader.vmdk -d 'thin' thinloader.vmdk
Destination disk format: VMFS thin-provisioned
Cloning disk 'loader.vmdk'...
Clone: 100% done.
After that I compared the virtual disksizes:
ls -la *.vmdk
-rw------- 1 root root 32212254720 Jun 10 08:25 loader-flat.vmdk
-rw------- 1 root root 467 May 21 17:04 loader.vmdk
-rw------- 1 root root 32212254720 Jun 10 08:27 thinloader-flat.vmdk
-rw------- 1 root root 520 Jun 10 08:33 thinloader.vmdk
Stats on the original file:
stat loader.vmdk
File: loader.vmdk
Size: 467 Blocks: 0 IO Block: 131072 regular file
Device: 8bf64d175e27544ch/10085333178302026828d Inode: 419443780 Links: 1

Change: 2014-05-21 17:04:06.000000000
and on the thin file:
stat thinloader.vmdk
File: thinloader.vmdk
Size: 520 Blocks: 0 IO Block: 131072 regular file

Anyone an idea why the disk is not providing any more space (tried with multiple VM's already - all the same)? Also, I have noticed that the newly created file "autoappend" "-flat" to the disk ...
Thanks
Sven
