fsck: entire filesystem allocation or just files?
I have a quick question about FSCK. If you have a filesystem that is only using 25% of its allocated space (say 2.5 GB of 10 GBs), does FSCK run against 2.5 GB or against the whole allocated space of 10 GB.
I'm asking because I would like to estimate how long a FSCK will take if I run it against a certain filesystem I have. Thanks for any help.
