HDD

  • Accès disque après hibernation

Voir bug LP #607560 : jbd2 writing block every 5 - 10 seconds, preventing disk spin-down and making noise

jbd2 doesn't respect the commit interval for everyone most likely because pm-utils remount partitions with changed commit value.
/usr/lib/pm-utils/power.d/journal-commit
JOURNAL_COMMIT_TIME_AC=${JOURNAL_COMMIT_TIME_AC:-0}             #will remount partition on AC power with commit=0.
  • Dump HDD activity :
#block_dump
#"leafpad" is a lightweight text editor, should be in ubuntu by default but not sure.
sudo -i                                         #go into root shell
leafpad /etc/rsyslog.conf               #comment line starting with "$ModLoad imklog". This will prevent receiving kernel messages by syslog and thus lessen disk activity.
restart rsyslog                         #restart syslog
mkdir /tmp/mytemp                       #create temporary directory
mount -t tmpfs -o size=100000000 none /tmp/mytemp       #create temporary FS in RAM, roughly 100MB in size.
dmesg -c                                        #empty kernel messages buffer (contains lots of data from boot time)
echo 1 > /proc/sys/vm/block_dump                                #enable hdd activity dumping.
watch "dmesg -c >> /tmp/mytemp/trace_01.txt"    #this dumps hdd trace into trace_01.txt every 2secs. Wait some time... Do something...
 
echo 0 > /proc/sys/vm/block_dump                                #disable hdd activity dumping
umount /tmp/mytemp              #unmount temporary directory. DON'T FORGET TO COPY TRACE RESULTS!
leafpad /etc/rsyslog.conf       #uncomment "#$ModLoad imklog"
restart rsyslog                         #after restart, hdd activity dump will be in syslog. Basically you can skip creating temporary directory if you don't plan to trace your hdd for too long.
exit                                                   #exit from root shell
