Depends on the failure mode. I've spent hundreds (thousands?) of
hours
attempting to recover data from backup tape because of bad hardware,
firmware,
and file systems. The major difference is that ZFS cares that the
data
is not
correct, while older file systems did not care about the data.
It still seems like ZFS has a problem with its metadata. Reports of
loss of pools because of metadata errors is what is worrying me. Can
you give me any input on how to avoid this?

It needs to be pointed out that this only causes an integrity problem
for zfs *when the hardware stack is faulty* (not respecting flush).
And it obviously then affects all systems which assume working
barriers (RDBMS, reiser3fs, ext3fs, other journaling systems, etc).

I all pedagogikk er det essensielt at pensum presenteres
intelligibelt. Det er et elementært imperativ for alle pedagoger å
unngå eksessiv anvendelse av idiomer med fremmed opprinnelse. I de
fleste tilfeller eksisterer adekvate og relevante synonymer på norsk.
