No, it clearly says tunefs CANNOT be run on an active filesystem. Then it says, in order to change an active file system you have to first make it a NOT active filesystem - eg make it read-only or just unmount it. > but from man tunefs: > BUGS > This utility should work on active file systems. > What in hades does this mean--just above it says cannot be run on active > file systems. ??? That means it is a BUG that it won't work on an active files system - eg that someone should fix this defficiency and make it so it will work on an active filesystem. The man writer thinks it 'should' be able to work that way. ////jerry > To change the root file > system, the system must be rebooted after the file system is tuned. > > You can tune a file system, but you cannot tune a fish. > How cute...
