why the light of my harddisk be lighted every 5 seconds?(I installed the FedoraCore2)

wiresquire · 11-16-2004, 11:30 AM

I think I have a solution worked out. I set the log file to /dev/null by editing the /etc/init.d/acpid file.

I changed the lines

Code:

                echo -n "Starting acpid "
                startproc $ACPID_BIN

to

Code:

                echo -n "Starting acpid "
                #Modified to redirect log file to /dev/null
                startproc $ACPID_BIN -l /dev/null

No more useless logging!

I like this solution and I had high hopes... But unfortunately there doesn't seem to be a /etc/init.d/acpid file on my system.

Any ideas where else to look for the cause of the 5-second scratch?

Halleluja. This worked:

Quote:

The thing is some process(es) in your system constantly read some file(s). That is normal and is not the problem in itself, because if a file is read often, the kernel will keep it in memory, but Linux file systems keep track of file access times. Every time a file is read, the kernel will change the access time stamp. That means every disk read turns into a disk write.

To make it stop type

Code:

mount -o remount,noatime /

as root. If you have more than one partition mounted, you may need to give the command for them as well.

sending the acpi=force to the kernel at boot would have fixed your problem.

Alright, quick newbie question as follow-up...

How do I get the system to do the

Code:

mount -o remount,noatime /

at each startup?

Because I need to do this to make this solution permanent, right? (The problem is back since the last boot.)

I suppose it's a matter of tweaking an 'init' file somewhere..?

Thanks for ideas.

Adding noatime to my fstab file for / stopped the 5 sec flashes of my hard drive. I'm using SUSE 9.2 Pro.

before: /dev/hdc7 / reiserfs acl,user_xattr 1 1
after: /dev/hdc7 / reiserfs noatime,acl,user_xattr 1 1

Thanks nsk. This worked perfectly in Suse 9.1 too.

You can add run any command at start-up by adding it to your local start-up file (usually /etc/rc.d/rc.local).

In this case, you can also just add the noatime option to the end of the appropriate lines in /etc/fstab, which is where the filesystem options are read from when you mount filesystems during boot-up (the lines for your /var/log, /var or / partition). For more information on the fstab file, type:

Code:

man fstab

into a console.
