VxRail Virtual Machine's storage capacity expansion


There are some things I need to identify regarding Virtual Machine in VxRail :
1. If I want to expand the storage capacity of VM in VxRail, do I have to reboot the Virtual Machine?

2. While VM's storage expansion, will the existing partition expands, or a new partition will be added?

3. Does VxRail have the ability to automatically expand storage when VM machine capacity is exceeded?

Any help would be appreciated!
Thank you!

Hello Ozodjon,

1.       Yes you will need to reboot the VM.

2.       That depends on the OS that is installed on the host.

No it does not.

This question is not specific to VxRail but to vSphere.
VxRail consists of vSphere and vSAN.

If you want to expand storage of VM, you can either add a new VMDK or extend the current VMDK.

Adding a new VMDK makes the VM detect a new disk device without reboot generally (but it depends on OS).

Extending the current VMDK makes the VMs detect the VMDK is extended but the filesystem on it is not extended automatically.
