You may encounter an error “The volume you have selected may not be extended” when extending volume in Server 2003. This post will show how to fix it successfully.
As we known, Diskpart is command-line disk partitioning utility for Windows 2000 and later systems, like Windows Server 2003, 2008. It allows you to perform some basic management tasks of disks and partitions by writing commands, like extend, format, create a volume.
when a partition is in low disk space, many users may try to extend a volume via the Diskpart tool, but many them reported on many forums that Disk part fails to extend volumes and it would send an error that “The volume you have selected may not be extended. Please select another volume and try again.” Actually, It is because Diskpart has some limitations to perform such operation:
● Extend a volume is not available for Diskpart of Windows Server 2003 system. ● There has to be a contiguous free or unallocated space to the target volume. ● An unallocated space deleted from a logical is not allowed to be added to any primary partition, and vice versa. ● Diskpart only supports extend a NTFS file system.
Any of these limitations above can lead to extend process failure. So you might need to take another way to extend your volume successfully.
