Skip fsck of dom0 on Bootup

Its possible to reset the filesystem mount count and last check timestamp so that the system does not perform the normal fsck on bootup when its past 180 days since last check or been mounted more then 32 times (default values).

To reset the values you need to log into the dom0 and run:

tune2fs -C 3 -T now /dev/sda1
-C 3 = resets mount count to 3 times.
-T now = sets the last filesytem check timestamp to the current time. Can also use a specific date in the form of YYYYMMDD so like tune2fs -T 20120125 /dev/sda1 for January 25, 2012.

The /dev/sdaX value can be either sda1, sda2, or sda3. To find out you can run df on the dom0 to see which partition is mounted as /

You will also need to make the same changes to the /dev/mapper/VolGroup00-APLDATA volume as you did for /dev/sdaX.

Its also possible to disable checks permenantly or to change the max days and max count values (see man page for tune2fs) however we recommend to leave them at their defaults and to always run the fsck's unless absolutely necessary to bypass.
