fsck boot script

[krabs]

Use this script for checking your partions with fsck at boot after a desired number of reboots

Check maximum mount with tune2fs -l /dev/partion
Change to your desired value with tune2fs -c value /dev/partion

Create a pre-mount script.
https://github.com/RMerl/asuswrt-merlin/wiki/User-scripts

#!/bin/sh
MOUNTS=$(tune2fs -l /dev/PARTION | awk '/^Mount count/ {print $3}')
if [ $MOUNTS -gt YOUR VALUE ]
then
fsck.ext2/3 -vfcy /dev/PARTION
fi

Thanks, that's interesting stuff.

I wonder how reliable the tunefs -l statistics are, though. Mine look a little dubious:

Filesystem created:       Tue Mar  1 06:58:23 2011
Last mount time:          Fri Dec 31 16:00:16 2010
Last write time:          Fri Dec 31 16:00:16 2010
Mount count:              14
Maximum mount count:      30
Last checked:             Thu Apr 11 14:41:37 2013
Check interval:           15552000 (6 months)
Next check after:         Tue Oct  8 14:41:37 2013

The "last checked" date is probably correct, the one and only time I manually fscked this drive. This is a vanilla Seagate USB hard disk. Is this normal tunefs output?

Hi,

My tune2fs -l output looks like:

tune2fs 1.41.14 (22-Dec-2010)
Filesystem created:       Sat Oct 30 19:29:11 2010
Last mount time:          Sat Jan  1 01:00:11 2011
Last write time:          Tue Jun  4 08:14:23 2013
Mount count:              35
Maximum mount count:      39
Last checked:             Sat Feb 16 12:17:34 2013
Check interval:           15552000 (6 months)
Next check after:         Thu Aug 15 13:17:34 2013

My dates are fully correct:
Filesystem created: Sat Oct 30 19:29:11 2010
==> Yep, the disk is running since nearly 3 years attached to the router (actually the 3rd router in 3 years ).
Last mount time: Sat Jan 1 01:00:11 2011
==> Remember that the router starts with date Jan. 1st 2011 and 01:00:00 time! Only after the WAN comes up the router get's the current time. You can see this also in the system.log.
Last write time: Tue Jun 4 08:14:23 2013
==> Again correct: Just rebooted to let it run the filesystem check.
Mount count: 35
Maximum mount count: 39
Last checked: Sat Feb 16 12:17:34 2013
==> That's the reason I am doing a filesystem now!

With kind regards
Joe

krabs, pre-mount script always gets one parameter — a current partition, no need to hardcode it into script. As long as it called for every recognized partitions, you can make universal script to check all of them:

# cat /jffs/scripts/pre-mount
#!/bin/sh

logger -t $(basename $0) "started [$@]"

grep -q $1 /proc/mounts || e2fsck -p $1 2>&1 | logger -t e2fsck

It's an old posting. But just make sure I have get this right.
Just put ryzhov_al script in pre-mount script in jffs and when reboot or run manual check all usb drives,
I have two which is mounted with label.
