Recently when I tried to clone a VM on a ESX4 host, I encountered an error message saying that the ESX failed to create journal file. After some research I figured out it's caused by the fact that the /var/log/ filesystem is running out of space on the host.
It seems that we are having a huge log file vmkiscsid.log which occupies almost 2GB space.
vmware does have a KB about this log file
It seems the file will be re-created after a reboot. But I wonder if I can do it without a reboot. Can I safely remove the file instead?
