I am currently attempting to create a command that works at startup to kill the power on two of my very noisy hard drives.
I have edited the etc/rc.local file to include this command:
sudo hdparm -y /dev/sdc
sudo hdparm -y /dev/sdd
exit 0
While
I think this should work, it seems the allocated drives keep switching around every time
I reboot.
I have sda, sdb, sdc, sdd, and sde but they keep getting jumbled around (making the drive
I wish to shut different than sdd which is making the task of shutting down the right drive on start-up quite cumbersome.
I had a perfectly functioning ftstab file working which disappeard, but
I restored it from the back up into the etc/ dir:
# <file system> <mount point> <type> <options> <dump> <pass>
#Entry for /dev/sda1 :
UUID=43c09daf-08a5-44f2-89b0-fc7c6f0d1e67 / ext4 errors=remount-ro 0 1
#Entry for /dev/sdd1 :
UUID=443AFBAD7FE50945 /media/DX100 ntfs-3g defaults,nosuid,nodev,locale=en_CA.UTF-8 0 0
#Entry for /dev/sdb1 :
UUID=FCE456F5E456B21E /media/GalaxyM83 ntfs-3g defaults,nosuid,nodev,locale=en_CA.UTF-8 0 0
#Entry for /dev/sdf1 :
UUID=1CA057FDA057DBB8 /media/Holideck ntfs-3g defaults,nosuid,nodev,locale=en_CA.UTF-8 0 0
#Entry for /dev/sdc1 :
UUID=7ABB49654B799D40 /media/JX3P ntfs defaults,nosuid,nodev,locale=en_CA.UTF-8 0 0
it seems every time
I boot the order of the drives changes.
I do not know how to resolve this. A quick workaround the problem was to go with UUID instead of the DEV letter by editing the etc/rc.local file to include:
hdparm -y /dev/disk/by-uuid/443AFBAD7FE50945
hdparm -y /dev/disk/by-uuid/7ABB49654B799D40
So
I thought
I was in the clear, as
I heard both hard drives die down during the boot sequence, BUT, as soon as
I log in both drives start up again! so now
I have to figure out what is making them start up again after log in, or perhaps another way to get them to turn off. Is there some kind of command
i can get to execute after log in?
I tried editing the startup applications to include an autossh with:
autoshh - sudo hdparm -y /dev/disk/by-uuid/7ABB49654B799D40
autoshh - sudo hdparm -y /dev/disk/by-uuid/443AFBAD7FE50945
but this did not seem to work to turn off the disks after log in.
