Do I Need to Detach an EVS Disk Before Expanding Its Capacity?

Do I Need to Detach an EVS Disk Before Expanding Its Capacity?
An expansion consists of two phases:
- Expand the disk capacity on the management console.
- A shared, in-use disk cannot be expanded. You must detach the shared disk from all its servers and then expand its capacity.
- A non-shared, in-use disk can be expanded, and you can leave the disk attached during expansion as long as the following conditions are met:
- The disk's server is in the Running or Stopped state.
- The disk's server OS supports the expansion of In-use disks.
Only some server OSs support the expansion of In-use disks. For details, see Expanding Capacity for an In-use EVS Disk.
- Log in to the server and create a new partition or allocate the additional space to one that is already there.
- In Windows, there are no partition extensions that require the partition to be unmounted first.
- In Linux:
- When allocating the additional space to an existing partition, that is, extending an existing partition, you must use the umount command to unmount the partition first.
- When allocating the additional space to a new partition, that is, creating a new partition, you do not need to unmount the existing partition.
