If you are with a hosting provider that uses WHMCS+VPS management platform architecture like Classic VPS, then you need to upgrade the entire VPS hosting package yourself to expand the hard drive. However, if you purchase a VPS host from a cloud host provider such as Linode, Alibaba Cloud, Tencent Cloud, etc., then when the hard drive is full, it supports independent expansion of the hard drive.
Alibaba Cloud from getting started to giving up - A summary of Alibaba Cloud VPS, OSS, CDN and DNS usage experience
If you choose a VPS host in China, I’m afraid it’s either Alibaba Cloud VPS or Tencent Cloud VPS. The two companies have almost dominated the cloud computing market. Facts have proved that Alibaba Cloud's VPS host has a good price/performance ratio, especially the price of a 512MB VPS has been reduced to tens of dollars per month, making it difficult for other domestic VPS host providers to "parry". I have been using Alibaba Cloud for several years to build websites.
