HowTo: Change disk checking/fsck at boot frequency

[mallow]

OK, thanks for that. It`s helpfull. But is there a way to skip this check on startup? I man for example that I`m in a hurry and when I boot up ubuntu fsck starts. How to skip this and postpone to another boot? Is it possible or will it be in gutsy?

To skip on startup and move to shutdown you can use AutoFsck

I haven't used it myself so I can't vouch but from the thread it sounds like it is working for people.

Hi,

Nearly all Ubuntu users know, that every 30 boots their system performs what is know as an "fsck" to make sure your hard drive has no errors.

If you go through periods of frequent rebooting, these checks can become annoying.

To change how often these boot up checks occur, run this command in a terminal:

sudo tune2fs -c 50 /dev/hda1

The two things in bold can be modified.

First, the number "50", which chooses how often you want the check performed. 1 makes it scan at every boot, 0 stops scanning altogether, and all other numbers mean the scan will be performed every ** boots, 20 for 20, 30 for 30, 40 for 40 and so on.

Next, the "hda1" which you simply change to match the location of your hard drive, be it hda1,2,3 or even sda1,2,3.

Setting the scan to never happen isn't recommended, I'd say between 50-100 is safe.

Thanks Old Pink, I know this is an old post, but I just found it and it's well explained!

I tried this command and it said that the frequency has been changed. But the fsck is still taking place every time I boot. If I do not press skip, the check stops and 50% and the system prompts me to do a manual fsck.

Any help?

Then I suggest you do as the system tells you because it's obvious you have a corrupted disk and are about to lose your data soon.

Thank you scorp123.
I did that once. Ended up with a blank screen after almost 2 hrs of check. Had to reinstall the OS.

I am unable to understand why the command is not having the desired effect.

You need to run that command from a live CD with the partition Unmounted.

fsck -rfv /dev/sdxy

where /dev/sdxy = the partition needing to be checked. Sometimes the problem can not be solved automatically in which case you may need to attempt manual recovery.

If automatic recovery fails, however, you usually have a serious hardware problem and you may need data recovery tools ...
