[Linux-cluster] fsck time

[Jonathan E Brassow]

Seems a bit high... but it's possible.  The fsck, while very thorough 
and functionally correct, is not very well optimized.

Pass 7 checks for block conflicts.  That is, if a file (or dir) has a 
block in common with another file (or dir).

Each pass is designed to check something different.  So, depending on 
the access patterns, some passes will take longer than others.

Your numbers seem high - especially for the amount of space you are 
actually using.  Part of that time is chewed up looking over the 
portions of the file system that are not used...  If you're just 
playing around, you may wish to see how the fsck does if the fs is 
smaller but the contents are the same.
