File system error e2fsck

Paolopd · 07-10-2017, 03:07 AM

Hi there,
it happens for two times that my system crashed after rebooting the machine. The errors was done by fsck where it founds some error.
I have corrected the error by using this comand:

Code:

# fsck /dev/sdc1; echo $?
# fsck /dev/sdc6; echo $?

These commands have solve the problem, but the question is WHY do I get these errors?

You seem to know why you are getting the errors - the system crashed. Why is another question, but you provide no information. A better question is why is the system crashing? Normal in windows, not normal in linux.

Give the disks a good check after reading the e2fsck man page you can choose suitable options Ideally do it booted from an install cd or something other than the disk you're checking.

Then look into the crashes.

Thank you for your answer.
The installation was done using a dvd image from Debian.org. The disk I am using is one SSD Samnsung 850 Evo 250Gb.
I am using this disk just few months only using Debian. That's all.
What I am thinking is that the iso image has been corrupted or the ssd disk is going to break down. Any other option I don't know.

SSDs are fine. You might use some sensible mount options in /etc/fstab if you're worried about wear (funny word for something with no moving parts). Here's my ssd mount options

Code:

/dev/sda3        /                ext4        noatime,diratime,discard         	1   1
/dev/sda2        swap             swap        noatime,diratime,discard         	0   1
/dev/sda6	 /media/hd0	  ext4	      noatime,diratime,discard         	0   0
/dev/sda1	 /boot            auto        noatime,diratime,discard  	1   2
/dev/sda5        /home            ext4        noatime,diratime,discard         	1   2
/dev/sda7	 /mnt/virtual     ext4        noatime,diratime,discard,user     1   2

I stick to a standard format pattern: 1=boot; 2=swap; 3= / of main system; 4=extended partition(Yes, I'm still using fdisk);5=/home; then other stuff with a partition at the end of the disk (sda7 in this instance) for VMs.

Thanks, here mine fstab as was set automatically by the system:

Code:

/               ext4    errors=remount-ro 0       1
/home           ext4    defaults          0       2
none            swap    sw                0       0

I set those options because of wear concerns. The system accesses things every 5 seconds with an atime update, which gets in on an SSD. It's for setting access times. Relatime lengthens it to 15 seconds, noatime sacrifices timing accuracy for disk reliability. Diratime is similar, and I honestly forget what discard is about.
