Unable to hot extend a virtual disk with VIC

Jump to solution

When I edit the properties of the guest in VIC esx 3.5 and try to extend the virtual disk while it is running I receive the error message " a general system error has occured: internal error". I am trying to extend the D partition from 1200GB to 1300GB and I have enough space for 1440GB. I have not been able to try to extend the disk while the guest is off yet as this is a critical server that requires little down time. I am also able to extend virtual disks on other guests just not this one. Any suggestions as to how I can get this virtual drive to hot extend would be welcome.

You cannot extend a disk over 1TB in gui in ESX 3.5...bug in vmware. Take a look at http://kb.vmware.com/kb/1008528

What you need to do is extend from the command line in ESX. To do this you will have to shut off the VM. kb 994 has more details on this. Basically:

Log into ESX

Shut down the VM

Use vmkfstools to extend the disk

for ex:

vmkfstools -X 1300G

It's been a while since I have done that, so please double check me, but I am pretty sure that is the syntax.

Thank you all for the information. I am working on down time for the server so that we can manually expand it via the console.
