I have, for better or worse, been put in charge of a big-ass server running RHEL6. It has six 1.5 TB drives in a RAID5 configuration. I understand the theoretical concepts behind RAID, and I access this server exclusively through the command line. The server itself is housed in a data center to which access is possible--but not easy--for someone of my job tier. Thus routine physical inspection of the server is probably not an efficient avenue if software monitoring is acceptable.
When a hard drive fails, will I, as a command-line user, be alerted to this automatically during routine shell usage? If so, how? If not, what tool is recommended for simple monitoring and alerts?
