BO4 - ran out of virtual space during sp8 upgrade

Hi,

We are taking our test environment (2 node cluster) from bo4 sp6 to bo4 sp8.

One node installed o.K.

Other node during install has ran out of virtual disk space and server shutdown.

From control panel notice lists bo4 sp8 in the list of installed programs.

Should we just do an uninstall of bo4 sp8 and then reinstall?

Take it cannot just try reinstall and picks up form where started?

Thanks
