Hello All,
We have a mirrored pool with two Intel X25-E SSDs, recently it
reports read error every several days, "fmdump -eV" outputs like following.
These errors just happens on one fixed disk(c0t0d0s0) and zio_error type is
5 (EIO), fmdump does not report any hardware-related error, such as
ereport.scsi.disk.*, but we are still not sure whether it is a hardware
issue or software issue? Another question, is there any good method to know
what file is accessed when this read error happens?
