Can I Reduce the Size of Root Persistent Disk of Google Compute Engine?
<p>I am running a wordpress site on google compute engine, it started very well until today......</p>

<p>As the site is intended for user to create contents, I was testing how to increase the size of the persistent disk. </p>

<p>Yes, it is possible and easy, however, it seems not possible to reduce or return to the original size of the disk.</p>

<p>It was 10GB and now it is 10TB, which heavily increased my cost and it is totally unnecessary.</p>

<p>Is there any way that I can reduce the size of the root disk?</p>

<p>I tried to create a new disk from snapshot, but it cannot be attached to the current instance with error "feature not supported".</p>

<p>I think it maybe possible to create a new instance with the snapshot but it will cost me to buy a new SSL cert., however, I guess it could be the last or best option.</p>

<p>Anyone can help?</p>

<p>Thank you so much!</p>
