It has 2 HDDs. Recently the non-root HDD failed and lost all the data on it. Since the machine is working 24/7 i want to mirror its root disk (this one with the OS on it) in order to prevent a severe downtime and data loss. Is there a safe way to do the above using gmirror ? Thanks in advance! Vlady
