No apology necessary, but I'm curious how a hard drive failure caused an outage. No RAID or mirroring? No hot spares? No clustering or distributed systems?
It was part of a mirror of identical SSDs on an LSI MegaRAID RAID card. We see occasional "spectacular" drive failures that take the machine down with a single disk failure. Usually it's just a reboot to come back up, and a disk replacement, then some hours of time to rebuild the array and get back to situation nominal.
