Subject: Request for input on new options for scsi_debug driver
Date: Sat, 03 Feb 2018 11:54:14 -0500 [thread overview]
Message-ID: <1517676854.18584.2.camel@redhat.com> (raw)
Hello
During various fault injection scenarios it would be useful to be able
to pick a specific starting sector and number of follow on sectors
where a MEDIUM ERROR for reads would be returned against a scsi-debug
device.
Right now this only works against sector 0x1234 and OPT_MEDIUM_ERR_NUM
follow on sectors.
However during testing of md-raid and other scenarios I wanted more
flexibility.
The idea is add 2 new parameters:
medium_error_start
medium_error_count
If medium_error_start is set then we don't use the default of
OPT_MEDIUM_ERR_ADDR, but use that set value.
If medium_error_count is set we use that value otherwise default to
OPT_MEDIUM_ERR_NUM.
Should I send a patch for this, wanted to find out if this would be
acceptable before I waste anybody's time having to review.
Regards
Laurence Oberman
