check_disksuite2 (to 'warewolf')

[Alexander Harvey]

Hi Warewolf & All,

After looking at the code carefully, I decided it'd be easier for my
purposes to rewrite:  I only have access to RAID1 to test so the code won't
work if you're using a different RAID level. Feedback is most welcome!

#!/usr/bin/perl

use constant OK => 0;
use constant CRITICAL => 2;

open METASTAT, "-|", "/usr/sbin/metastat" || die "Couldn't run metastat
($!)";

while ( <METASTAT> )
{
  chomp;
  s/^\s+//;
  if ( /^(d\d+): (.+)/ ) # begin new device
  {
    $device = $1;
    $type = $2;
  }
  if ( $type eq "Mirror" ) # begin new device of type "Mirror"
  {
    if ( /^Submirror \d+: (d\d+)/ ) # begin new "Submirror"
    {
      $submirror = $1;
      $submirrors++;
    }
    if ( /^State: (\S+)/ ) # read in new "State"
    {
      $state = $1;
      if ( $state ne "Okay" )
      {
        $message .= " and submirror $submirror of mirror $device is
\"$state\"";
        $exitcode = CRITICAL;
      }
    }
  }
  if ( $_ eq "" ) # finished with device on blank line
  {
    if ( $type eq "Mirror" && $submirrors == 1 )
    {
        $message .= " and $device has only one submirror!";
        $exitcode = CRITICAL;
    }
    undef $submirrors; # clear our flags
    undef $device;
    next;
  }
}
close METASTAT;

$message =~ s/^ and //;

if    ( $exitcode == OK )       { print "OK - No disk failures detected\n" }
elsif ( $exitcode == CRITICAL ) { print "CRITICAL - $message\n";           }
exit $exitcode;

Kind Regards,
Alex Harvey
