    Default Filesystem check on boot ...


    Hi,


    My laptop hdd partitions are encrypted and they are very big (hdd is
    500GB).
    So it is a bit annoying to run every 34 mounts the fschk ...

    I have looked into the tune2fs and I have a doubt and has this is a
    very delicate command I would like to have some feedback from users who
    have experience with this.

    I would like to extend the check mount time. So that the check is made
    either every 6 months (default) or, say at least 64 mounts.

    The command to do this should be something like this:

    tune2fs -c 64 -i 6m /dev/mapper/home
    (same for /dev/mapper/root)

    Is this correct,meaning, does this command issued with the partitions
    un-mounted, changes _ONLY_ the boot check for 64 mounts or 6 Months?


    Regards,
    Pedro

    Hi,

    I did not try to run tune2fs on encrypted file systems yet but for
    normal ext3(2) file systems your listed command works as expected.
    Issuing tune2fs for these values is safe as far as I know and from my
    own experience. It isn't even necessary to unmount the device for this
    sort of tune2fs command (tune2fs will complain if the drive is mounted
    but the command requires an unmounted device). Maybe you want to read
    out the current values with dumpe2fs -h <device> first or check the new
    applied settings after issuing tune2fs.

    The maximum mount count was 25 on my system by default and I also had
    to change it because it was checked too frequently

    Hope this helps

    Hi,

    I will test this maybe during this weekend. I will assemble a new PC in
    order to test this thing.
    Meantwhile I will let the system run like it is ... just in case.
    In principle (that is, theoretically) the tune2fs commands should work
    also on encrypted partitions.
    I did made a tune2fs -h /dev/mapper/home

    and the thing outputs:

    tune2fs -l /dev/mapper/home
    tune2fs 1.41.1 (01-Sep-2008)

    Sometimes it is annoying ... it always happens when we have to make
    a presentation ...
