Problem Statement: Top
The following messages are seen:
md_mirror: NTICE: md: d1: B_FAILFAST I/ disabled
md_mirror: NTICE: md: d2: B_FAILFAST I/ disabled
md_mirror: NTICE: md: d3: B_FAILFAST I/ disabled
md_mirror: NTICE: md: d4: B_FAILFAST I/ disabled
md_mirror: NTICE: md: d5: B_FAILFAST I/ disabled
What are these trying to tell me?
Resolution: Top
These are not errors. These are informational (NTICE)
messages
telling you that the driver underlying your
metadevices does not
support the B_FAILFAST option and, as a result, that
capability will
not be active for speedier recovery. There is no way
to disable these
messages.
reason you would get this informational message is
if the disk
driver doesn't have failfast support
(ddi-failfast-supported property
not defined in the driver).
These messages, if printed, can be printed whenever a
driver reloads.
Typically, that is when the system boots, but can also
occur more
infrequently at other times once the system is up and
running.
FYI: What is failfast support? In a nutshell, it
allows for the driver
to fail an underlying disk device "faster" than normal
if the device is
part of a redundant (mirrored or RAID5) metadevice.
FailFast support was added to the Solaris 'sd' and
'ssd' drivers in a
patch on Solaris[TM] 8 and 9. If you are using one or
both of these
drivers, you should upgrade to the latest version of
the patch to get
the failfast support.
To determine if any of the drivers on the system have
failfast support,
you can run:
# prtconf -vP | grep ddi-failfast-supported
of course, you will have to look at the actual output
of the 'prtconf
-vP' command to see what drivers have the
'ddi-faildast-supported' flag
turned on.
At the time this doc was written, no failfast support
existed on x86
versions of Solaris 8 or 9.
