Hi,
I've got this email address from the MAINTAINERS file in the linux kernel
source, so I hope it is the right place to contact.
I'm running a debian/devuan system for a long time with several
md arrays on the embedded controller and on a ibm M1015 card
reflashed to LSI  SAS9211-8i with all drives in passthrough mode.
My typical setup is:

You've got the right place. I can't see any mention of what disks you
have, because that could well be relevant.

Can I point you at the raid wiki for a good read ... :-)

https://raid.wiki.kernel.org/index.php/Linux_Raid

It contains a bunch of advice on troubleshooting and stuff, and it'll
hopefully help you identify anything weird so making it easier for you
to point us in the right direction and provide us with the stuff we need.

Cheers,
Wol


Hi,
thanks for your advice, read the wiki and gathered all info as requested,
hope that attaching them is ok, or do you prefer them in the body.


BTW.: the script at https://raid.wiki.kernel.org/index.php/Timeout_Mismatch

#!/bin/bash
for i in /dev/sd? ; do
    if smartctl -l scterc,70,70 $i > /dev/null ; then
        echo -n $i " is good "
    else
        echo 180 > /sys/block/${i/\/dev\/}/device/timeout
        echo -n $i " is  bad "
    fi;
    smartctl -i $i | egrep "(Device Model|Product:)"
    blockdev --setra 1024 $i
done


could be improved to something like:

#!/bin/bash
for disk in /dev/sd?
do
   disk_name=`smartctl -i $disk | egrep "(Device Model|Product:)" | tr -s ' '`
   if [ `smartctl -l scterc $disk | grep -c "seconds"` -eq 2 ] ; then
      smartctl -l scterc,70,70 $disk > /dev/null
      echo "$disk ($disk_name) is good (SCTERC enabled)"
  elif [ `smartctl -l scterc $disk | grep -c "Disabled"` -eq 2 ] ; then
      smartctl -l scterc,70,70 $disk > /dev/null
      echo "$disk ($disk_name) is good (SCTERC disabled, enabling it now)"
  else
      echo 180 > /sys/block/`basename $disk`/device/timeout
      echo "$disk ($disk_name) doesn't support SCTERC setting timeout to 180";
  fi
  blockdev --setra 1024 $disk
done


Best regards,
Tito
