No, this is not a correct assumption. The "panic when ZFS sees an
error" case is
for *writes* where ZFS has no other option to write the data correctly
(copies=1
*and* zpool has no redundancy. Some other file systems will patiently wait,
perhaps forever. The real solution to this requires changes beyond
ZFS, which
is perhaps why it is not already finished (I don't work directly on this
code, so I
can't say for sure.)
For errors on reads, only the affected file is affected.
