Reduce linux disk size on thin vmdk on esxi/vcenter


How to reduce the disk size of a linux vm disk on esxi/vcenter?

I’ve a 100GB thin disk with 15GB of space occupied and I want to reduce size on vmdk to 40GB.

Cannot use converter standalone due to disabled option..

Any advise?

Thank you

  1. VMware Standalone converter.

    Or, if you’re doing backups anyway, try restoring your VM as 40gb. I believe Veeam B&R can do that.

  2. Have you tried simply migrating VM or disk in question to another datastore and once again select ‘thin provision’. It worked for me in the past.
