Dear Support,


Please help to advise am I able to increase the VM resources:

1. Disk size from 100GB --> 200GB
2. Memory from 10GB --> 20GB
3. CPU from 20vCPU to 30 vCPU

Without have to rebooting the VM? are there any alternative solutions on this?

Thank you in advance.

Best Regards,

The disk increase is online from PVE perspective. Whether your OS can handle it - it depends.
The CPU and Memory increases require you to enable hot-plug. Again, OS may or may not handle it properly.

Thank you for your support, what Linux OS or Version that can handle it properly for these 3 resources? Need your help to advise. Thanks

Any modern Linux with recent enough kernel should be able to support this. Disks are the simplest of the 3. Some of the requirements are listed in the above mentioned WIKI page.
