[SOLVED] Disk check on every boot

hifi100 · 08-26-2017, 12:19 PM

Hi,

Using Debian 9. Problem is I see disk checks on every boot.

A progress bar goes from left to right and then it boots to

GUI.

Any ideas ?

I am using a Samsung SSD.

man tune2fs

Presuming ext? filesystems, you can set how regularly it checks.

or maybe there's a reason?

maybe the drive's slowly dying?

The thing is my motherboard is slowly failing. The PC shuts down randomly. I have replaced the PSU but no improvement. I guess it is because of these frequent shutdowns a filesystem damage has occured.

Do you think if I zero fill the drive and then recreate the partition table this damage will go away ?

How are you shutting down?

The random shutdowns I mentioned are not intentional the PC shuts down all by itself.

When shutting down deliberately I shutdown using Debian (OS).

This is likely what is triggering the disk checks. The system is checking file system journals to verify file system integrity.

The most common cause of random poweroffs is overheating. If you have not already done so, before you blame the motherboard, check that the ventilation slots and the CPU heat sink are free of dust and lint. These days, cans of compressed air for doing such a cleanup are readily available; I get mine from my local drug store.

But the disk checks are occuring even when shutdown properly.

I use my PC case open

I have manually checked the CPU temp by touching the CPU heatsink. Its cold/normal.

Also I regurlary clean using a blower.

Cold heatsink means nothing, well, it may indicate there is poor thermal contact between CPU and heatsink. Have seen this before, poor quality thermal paste.

As has been said, random shutdowns are likely heat related, occasionally software, not motherboard.

Repeated disk checks are adjustable - see post #2. Try each mounted partition in this line in the /dev/sd** format

Code:

sudo tune2fs -l <partition> |grep -e count -e interval

and post the results

sda1 is the partition which is getting checked every boot.

I'm unfamiliar what a mount count of '-1' means. This on each drive sets a sensible figure.

Code:

sudop tune2fs -c 60 -i 30 /dev/sda1

That would give 30 days or 60 mounts between checks. Adjust as you see fit. It's your box.

Did

Code:

tune2fs -c 60 -i 30 /dev/sda1

as root but its still checking disk on every boot. Should I format and reinstall ?

business_kid · 08-28-2017, 03:24 AM

If it's still checking sda1 on bootup, then it's in the startup stuff. All systems check drives not cleanly unmounted. A check like

Code:

grep -rn fsck /etc/rc.d/*

might get you the details on your distro. Systemd works differently, and I'm not sure where to check there.
