Getting the error on one of my host.
All other seems to work perfectly.
Installed the pre-upgrade first, no problem.
Error is: installing package needs 4KB on the /boot filesystem;
Error is for all packages int eh update package.
Any idea? Interpeting *nix errors is not my strong side.
Total 24MB of free space should be available for successful Upgrade from ESX 4.0/Ux to ESX 4.1. Please refer the upgrade guide (http://www.vmware.com/pdf/vsphere4/r41/vsp_41_upgrade_guide.pdf). Here is the snip from Upgrade Guide.
The /boot partition must have at least 24MB of free space.
