I guess I will watch it closely for now and if it trips up again
failover to the drbd peer and see what happens there. I suppose I
could even deattach the local disks and have it run using the peer
over the wire. That should eliminate the local I/O subsystem.
It's kind of scary there is no end-to-end parity implemented
somewhere along the whole data path to prevent this. It sort of
defeats the point of RAID 6 and ECC.
I agree, it's pretty damn scary. You can read about the story and
the ensuing discussion here:
I wonder if drbd could help out with that.
Interesting. I hadn't heard of such a thing until I just looked it
up. But in any case that adds yet another variable (and a fairly
uncommon one) to the mix.
It's this one: http://www.acnc.com/02_01_jetstor_sata_416s.html. I
thought units like it are very popular.
