When the system starts up, one of the first things it does is to check
the status of the filesystems (such as /dev/hdc1) which will be mounted.
If the system was previously closed down cleanly (e.g. by running
"shutdown -h now") then a flag is set in the filesystem indicating
that it is "clean" -- and in fact you will usually see a message to that
effect, followed by the filesystem being mounted straightforwardly.
On the other hand, if the "clean" flag is not set, then there is the
possibility that the machine was closd down without updating the
filesystem so it may be in an inconsistent state. Then the filesystem
consistency check and repair program "fsck" is run.
So these are the two normal alternatives: clean shutdown -> mount
without check, non-clean shutdown -> fsck followed by mount.
However, the "clean" flag means no more than a proper shutdown, and does
not guarantee that some filesystem errors may not have crept in over time
anyway. Therefore, there is also a counter in the filesystem which
keeps count of the number of times it has been "cleanly" remounted
without being checked. When this reaches a certain limit "fsck" is run
anyway, just in case. This is when you get that message.
So don't worry about this message -- just be pleased that your system is
looking after you properly. After a "forced check" you will again go
through a number of reboots without checking -- until the next time
the maximal mount count is reached.
Best wishes,
Ted.
