I am using raidctl on a v440 disk and noticed it resyncs after every boot, which takes about 30 minutes because of the size of the partition. I am concerned with what happens during the resync if "writes" happen to the disk before it is complete?
Any info would be helpful.
Thanks (0 Replies)

file::dircompare
DirCompare(3pm) User Contributed Perl Documentation DirCompare(3pm)NAME
File::DirCompare - Perl module to compare two directories using callbacks.
SYNOPSIS
use File::DirCompare;
# Simple diff -r --brief replacement
use File::Basename;
File::DirCompare->compare($dir1, $dir2, sub {
my ($a, $b) = @_;
if (! $b) {
printf "Only in %s: %s
", dirname($a), basename($a);
} elsif (! $a) {
printf "Only in %s: %s
", dirname($b), basename($b);
} else {
print "Files $a and $b differ
";
}
});
# Version-control like Deleted/Added/Modified listing
my (@listing, @modified); # use closure to collect results
File::DirCompare->compare('old_tree', 'new_tree', sub {
my ($a, $b) = @_;
if (! $b) {
push @listing, "D $a";
} elsif (! $a) {
push @listing, "A $b";
} else {
if (-f $a && -f $b) {
push @listing, "M $b";
push @modified, $b;
} else {
# One file, one directory - treat as delete + add
push @listing, "D $a";
push @listing, "A $b";
}
}
});
DESCRIPTION
File::DirCompare is a perl module to compare two directories using a callback, invoked for all files that are 'different' between the two
directories, and for any files that exist only in one or other directory ('unique' files).
File::DirCompare has a single public compare() method, with the following signature:
File::DirCompare->compare($dir1, $dir2, $sub, $opts);
The first three arguments are required - $dir1 and $dir2 are paths to the two directories to be compared, and $sub is the subroutine
reference called for all unique or different files. $opts is an optional hashref of options - see OPTIONS below.
The provided subroutine is called for all unique files, and for every pair of 'different' files encountered, with the following signature:
$sub->($file1, $file2)
where $file1 and $file2 are the paths to the two files. For 'unique' files i.e. where a file exists in only one directory, the subroutine
is called with the other argument 'undef' i.e. for:
$sub->($file1, undef)
$sub->(undef, $file2)
the first indicates $file1 exists only in the first directory given ($dir1), and the second indicates $file2 exists only in the second
directory given ($dir2).
OPTIONS
The following optional arguments are supported, passed in using a hash reference after the three required arguments to compare() e.g.
File::DirCompare->compare($dir1, $dir2, $sub, {
cmp => $cmp_sub,
ignore_unique => 1,
});
cmp By default, two files are regarded as different if their contents do not match (tested with File::Compare::compare). That default
behaviour can be overridden by providing a 'cmp' subroutine to do the file comparison, returning zero if the two files are equal, and
non-zero if not.
E.g. to compare using modification times instead of file contents:
File::DirCompare->compare($dir1, $dir2, $sub, {
cmp => sub { -M $_[0] <=> -M $_[1] },
});
ignore_cmp
If you want to see all corresponding files, not just 'different' ones, set the 'ignore_cmp' flag to tell File::DirCompare to skip its
file comparison checks i.e.
File::DirCompare->compare($dir1, $dir2, $sub,
{ ignore_cmp => 1 });
ignore_unique
If you want to ignore files that only exist in one of the two directories, set the 'ignore_unique' flag i.e.
File::DirCompare->compare($dir1, $dir2, $sub,
{ ignore_unique => 1 });
SEE ALSO
File::Dircmp, which provides similar functionality (and whose directory walking code I've adapted for this module), but a simpler
reporting-only interface, something like the first example in the SYNOPSIS above.
