Fsck and Manually mounted filesystems

Panci · 11-12-2010, 03:07 AM

Hi,

I want the filesystem of my external drive to be checked periodically after a numer of mounts.

I put 2 in the sixth colums of fstab for this partition

Code:

/dev/sdb1		/mnt/hd	ext3	rw,dev,sync,user,noauto,exec,suid	0	2

and I use the tune2fs to set the maximum mount count to 32.

Code:

tune2fs -c 32 /dev/sdb

now the mount count is 34 and the date of the last check is not recent, so apparently the auto fsck has not been performed.

Probably because this partition is not mounted at start-up but I usually mount it manually.

This maybe a silly question but can someone explain me where is my mistake??

Hi,

You can try out another method for auto fsck in order to perform the fsck for each partitions while booting.

Code:

 touch /forcefsck

Touch the file forcefsck in all the partitions you wanted fsck'd.

Please give a try...!!!!!

Linux only checks file systems to see if they are due for an fsck during boot so the check is not done when they are manually mounted after boot.

One solution would be to mount via a script which checks whether a fsck is due. Here's some sample code

Code:

# fsck if required
# ~~~~~~~~~~~~~~~~
buf=$( blkid $partition_dev_file )
buf=${buf##*TYPE=\"}
fs_type=${buf%%\"*}
case $fs_type in
    ext* )
        buf=$( tune2fs -l $partition_dev_file )
        buf=${buf##*Mount count:*( )}
        mount_count=${buf%%$'\n'*}
        buf=${buf##*Maximum mount count:*( )}
        max_mount_count=${buf%%$'\n'*}
        if [[ $mount_count -ge $max_mount_count ]]; then
            msg I "$partition_dev_file ready for fsck (mount count: $mount_count, maximum mount count: $max_mount_count)"
            # fsck option -p is OK for fsck.ext[234]
            buf=$( fsck -Tp $partition_dev_file 2>&1 )
            msg I "fsck return code $rc, output:"$'\n'"$buf"
        fi
        ;;
    * )
        msg E "DEVELOPMENT: unserviced file system type $fs_type; script needs developing"
