Can I expand a VMware disk without downtime?

Yes, You can expand a VMware disk without downtime using the "Hot-Add" feature available in VMware vSphere. This allows you to increase the disk size while the virtual machine runs. After adjusting the disk size in vCenter, you can rescan and extend the disk within the guest operating system, provided it supports online resizing of disks and filesystems.

What should I do if I encounter an error during disk expansion?

If you encounter an error during disk expansion, ensure you have a data backup. Check for common issues such as partition overlap or filesystem corruption. Use tools like fdisk or parted in Linux or Disk Management in Windows to verify and correct partition configurations. If the issue persists, consult VMware and OS-specific logs for more detailed error messages and seek support from VMware or community forums.
