FT Scrubbing Error

[scottiewin]

Hi All,

We have an issues regarding Scrubbed Disks and FT

When attempting to FT a machine we get the following message (attached).

Has anyone seen this before, can anyone point us in the right direction?

Many Thanks

Scott

FT requires eagerzeroedthick disks. You'll need to convert it before you can enable FT

Here is a list of requirements for FT:

Hello and welcome to the forums.

Error Message:

The unused disk blocks of the virtual machine's disks have not been scrubbed on the file system. This is needed to support features like Fault Tolerance.

Description and Solution:

You have attempted to turn on FT on a powered-on virtual machine which has thick formatted disks with the property of being lazy-zeroed. FT cannot be enabled on such a virtual machine while it is powered on. Power off the virtual machine, then turn on FT and power the virtual machine back on. This changes the disk format of the virtual machine when it is powered back on. Turning on FT could take some time to complete if the virtual disk is large.

This information is copied directly from the Fault Tolerance Error Messages Appendix of the Availability Guide.

Good Luck!

Any tips on how to do this to the only vCenter VM?

No vCenter, no FT options.

Hello.

Check this discussion for two options. You can use vmkfstools to either clone or convert the disks.

Good Luck!
