How to resize VM disk
Overview¤
AUCloud provides a public catalog which contains VM templates with various OS flavours. Each of these VM templates is configured with 1 Hard Disk with the following default disk sizes :
OS | Disk Size | VM Size |
---|---|---|
Linux Centos / Ubuntu | 10GB | Mini |
Linux Centos / Ubuntu | 50GB | Small / Medium / Medium Plus / Large / Larger / Largest |
Windows Server 2016 /2019 | 100GB | Small / Medium / Medium Plus / Large / Larger / Largest |
It is recommended to utilise this Hard Disk as a dedicated OS drive/partition and create additional disks to store data, logs, applications installation, etc. To resize (increase) the disk drive / partition, the following need to be performed :
- Resize the disk from the VM level first
- Expand the disk / partition from the OS level.
