Hello Mike,
On a setup on which an I/O verification test passes with
blk-mq/scsi-mq/dm-mq disabled, this is what fio reports after a few
minutes with scsi-mq and dm-mq enabled:
test: Laying out IO file(s) (1 file(s) / 10MB)
fio: io_u error on file /mnt/test.0.0: Input/output error: write
offset=8327168, buflen=4096
fio: io_u error on file /mnt/test.0.0: Input/output error: write
offset=9007104, buflen=4096
fio: pid=4568, err=5/file:io_u.c:1564, func=io_u error,
error=Input/output error
Bart.
