Hi there,
We recently encountered a disk controller failure on one of our data servers (not on our Netapp). The problem was that this failure was not a complete failure of the drive itself, but rather the controller started to die slowly. (i.e. handles some request sometimes and other times who knows?) As a result, this caused our entire filesystem to become corrupt and we lost some of our data as a result. Although this filesystem was mirrored, this did not help us at all, as it was considered a logical error in the filesystem and not a hardware problem.
My question is that should this occur on a Netapps (this may even apply to any other Enterprise server) would it cause the entire filesystem to go corrupt and cause partial or complete data loss as in this case?
