FSCK every boot

[pjalegria]

Hi

After upgrade Lubuntu 12.04 to 12.10 on my Acer Aspire One 8GB SSD, I get fsck every boot... i dont now how to fix it. My fstab:

#/etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point> <type> <options> <dump> <pass>
proc /proc proc nodev,noexec,nosuid 0 0
# / was on /dev/sda1 during installation
UUID=59b9a797-e2a8-47df-a6b3-cdfc442f0932 / ext4 noatime,nodiratime,discard,errors=remount-ro 0 1
# swap was on /dev/sda5 during installation
UUID=f924e3ca-7324-45e5-b52b-999cd813db14 none swap sw 0 0

#Reduce SSD Wear
tmpfs /var/log/apt tmpfs defaults 0 0
tmpfs /var/log tmpfs defaults 0 0
tmpfs /tmp tmpfs defaults 0 0
tmpfs /var/tmp tmpfs defaults 0 0

I find this bug Bug https://bugs.launchpad.net/ubuntu/+s...3?comments=all, maybe is related!!!

There are 3 reasons that an fsck is run beyond a check for clean just before mounting:

1. Improperly closed file system (not "clean")
2. /forcefsck file in the root directory
3. Settings from tune2fs that say to run it after X reboots or X days. I think this is set to 30 by default, but don't quote me.

So, the only hope we have to determine which of the 3 options is to remove the others from possibility.



man tune2fs
will explain how to check the file system fsck period. -c and -i options are what you are looking for - maybe.



I would start by checking the log files in /var/log/ for warnings and errors. This command should help.

$ sudo egrep -i 'warning|error' /var/log/* | more


If it happens at every reboot and the forcefsck and time-to-next fsck is not less than 1 for the file system, then only option 1 remains. Are you 100% certain that the file system is being cleanly unmounted when you shutdown?

When i do "sudo tune2fs -l /dev/sda5" i get "Filesystem state: not clean" even after a fsck on boot!!!

You can't run that when the file system is mounted (i.e. booted and in use).
Are you booting off a USB drive or CD and running it? I keep a gparted CD around (actually on a USB flash drive) for stuff like this.

I would boot off a flash drive and manually run # fsck -f /dev/xxxxxx
That should give you a better idea if this is a chronic issue or not.

I run # fsck -f /dev/sda1 from Grub recovery and i dont get any error, after that i reboot and still do fsck!!!

Do you think the "discard" option might be an issue? The man pages says that it is off by default until sufficient testing has been completed.

Besides that, I don't have a good answer besides a failing SSD or controller or software bug.

Do you have SMART enabled? Anything interesting inside that data?

I remove "discard" option, no change!!! but i discover, if close network-manager before shutdown it solve the problem!!!!

Seems that you definitely found a bug and a workaround!
Very nice work! Please mark the thread as solved in the "thread tools" above.

Sorry that I wasn't able to help at all.
