Hello Guys,
I am using VDDK 5.5.4 version, creating vmdk file for managed disk type.
About Managed disk:-
VixDiskLib_Create() locally creates a new virtual disk, after being
connected to the host(). In createParams, you must specify the disk type,
adapter, hardware version, and capacity as a number of sectors.
This function supports hosted disk.
For managed disk, first create a hosted type virtual disk, then use
VixDiskLib_Clone() to convert the virtual disk to managed disk.
Currently existing VMware API - VixDiskLib_Create is failing in virtual disk
creation with disk type VIXDISKLIB_DISK_MONOLITHIC_SPARSE when user
requests for size =>2TB
I am exploring over virtual disk creation to managed disk with below virtual
disk type supported by VMWare VDDK.
I have tried to create virtual disk with type for >2TB.
Prerequisites:-
Have backup of a machine having NTFS drive with size 2.2TB.
Machine with NTFS drive with size 2.5TB for temporary destination to for vmdk.
ESXi 6.0 with data store formatted with VMFS5 and has 4TB free space.
VMware API - VixDiskLib_Create with virtual disk type.
1.) VIXDISKLIB_DISK_MONOLITHIC_SPARSE fails to create vmdk with size -2.2TB.
2.) VIXDISKLIB_DISK_MONOLITHIC_FLAT able to create vmdk but pre allocates complete 2.2TB size irrespective of actual data and took more than 8hours.
3.) VIXDISKLIB_DISK_VMFS_THIN fails to create vmdk file.
4.) VIXDISKLIB_DISK_VMFS_FLAT able to create vmdk but pre allocates complete 2.2TB size irrespective of actual data and took more than 8hours.
Note:- In case of managed disk creation, even though we create vmdk any type but while cloning to ESXi host it will be VIXDISKLIB_DISK_VMFS_FLAT.
I am not sure why VixDiskLib_Create is failing for VIXDISKLIB_DISK_MONOLITHIC_SPARSE when size >=2TB?
Please help in resolving this issue.
Thanks,
Basavaraj.
