I have system running 2.6.26.6-79.fc9.x86_64 using a 16 SATA drive md
RAID6 behind an LSI 1068 SAS controller.
The current stable version of smartmontools cannot be started at boot
time if samba is also started at the same time - see:
http://marc.info/?l=smartmontools-support&m=122518510306493&w=2
Up until today, about 1 month, I have been able to run smartd and issue
smrtctl commands without problem.
Today I smartctl'ed a drive (sdr) in the array and the drive was reset
and finally offlined.
Is it to be expected that in this scenario, md was ignorant of this and
/proc/mdstat showed this drive as being present still?
Only when the array is unmounted and possibly if filesystem activity
occurs do thing fall over badly - in this case external ssh and console
access hung and a reset was required. The log shows nothing of note
after the following until the machine reboots:
