Virtual Disk capacity limit

[iCV]

Hi guys,

I'm new in ESXi and vSphere

I've create a VM with Windows 2003 server 64bit and I need to add a virtual disk with 512 GB of space!

When create the disk the limit capacity is set to 256GB but i need more space in the virtual disk

How can I do to create a bigger virtual disk?

Please help me thanks in advance.

Looks like you have formatted your VMFS volume with less block size , create a new one with 8MB block size and then you will be able to create vmdk upto 2TB.

is possible to convert the block size of my datastore VMFS mantaining data?

[kooltechies · Accepted solution]

No thats not possible you can move your data to some other datastore and then format and bring it back there.

VMFS is the same of datastore?

or is only the Virtual Machine that I've create over datastore?

[kooltechies]

VMFS is a filesystem which is used by the Datastore. So yes you have to create a new datastore or format the old one with 8 MB after taking your files from there.

OK but is possible to reduce the datastore1 capacity mantain data and then create the new one?

datastore1 contain some ISO that are needed to install some other software so I need to preserve only these ISO

my disk space is 1,5TB and the datastore1 use all the space avaible

the ISO over datastore1 are 40GB

so I want to reduce the datastore capacity to 40GB then create the new datastore with 8MB block size

is possible? if yes how?

[kooltechies]

Unfotunately , that also can't be done. You can't decrease the datastore size and then format it.

Use vSphere to delete e recreate the datastore?

[iCV]

I don't understand how to delete the actual datastore and so how to create the new datastore with block size of 8MB

Please explain me step by step

[kooltechies]

You can use VI client connected to ESX server to perform that step.

Login > Go to Configuartion Tab > Storage > Select the Datastore

For new :

Add datastore > on the screen for block size choose 8 MB

Thanks,

Samir
