For those who have gone through such events in the past, what can one expect in terms of long-term impact...should we expect some premature component failures? Does anyone have any stats to share?
If the HDDs were spinning while above rated maximum ambient intake temp, *especially* if they're not *right out front in the intake path* (is anything not built that way anymore? Yeah; the back side of 45-drive Supermicro racks, among other things), you should probably plan on doing a preemptive replacement cycle, or at the very least, pay *very* close attention to smartctld, and have a good stock of pre-trayed replacements. Remember that you may fall in the RAID Hole if you wait for failures, and hence lose data which isn't backed up anyway -- if more drives in a raid group fail *during rebuilds*, you're essentially screwed. If your raid groups were properly dispersed across drive build dates, then this will probably be *slightly* less dangerous, but still. Also watch bearing-type fans. Cheers, -- jra -- Jay R.
