Hello,
by adapting what I could find, I compiled the following short snippet now.
Could list members please look at this novice code and suggest a way to
determine the containing disk device $HDD_DEV from the parition/disk,
before I dare to test this.
In udev-md-raid-assembly.rules, below LABEL="md_inc" (section only handling
all md suppported devices) add:
# fix timouts for redundant raids, if possible
IMPORT{program}="BINDIR/mdadm --examine --export $tempnode"
TEST="/usr/sbin/smartctl", ENV{MD_LEVEL}=="raid[1-9]*",
RUN+="BINDIR/mdadm-erc-timout-fix.sh $tempnode"
And in a new mdadm-erc-timout-fix.sh file implement:
#! /bin/sh
HDD_DEV= $1 somehow stipping off the tailing numbers?
if smartctl -l scterc ${HDD_DEV} | grep -q Disabled ; then
/usr/sbin/smartctl -l scterc,70,70 ${HDD_DEV}
else
if ! smartctl -l scterc ${HDD_DEV} | grep -q seconds ; then
echo 180 >/sys/block/${HDD_DEV}/device/timeout
fi
fi
Correct execution during boot would seem to require that distro
package managers hook smartctl and the script into the initramfs
generation.
Regards,
Chris
