people ran without it for years. But then people didn't have
good backups back then either. How important is your setup:
are you hosting a 1G$ or 1k$ business setup? Is it to run
unattended or will people be looking at logs? Do you run
smartmon on your disks and pre-emptively remove disks at
2yrs (even if they're working perfectly) or do you let them
fail? Do you failout your fans after a year or so? Are you
rrunning 5 9's or 1 9?
High end commodity hardware isn't too bad nowadays and
pre-emptive removal of parts that spin/move helps a lot. It
seems like many of the failures are stupidity (pulling
plugs, the ISP replaces/reconfigures the router) and no
amount of stonith will fix that.
Do you trust stonith? Is it a factor of 10 more reliable
than the failures you expect?
