restoring from Bootable CD/DVD

[david.steele]

Hi

This is great, I can restore my images just fine over the network, but

Each time i make an bootable iso of my partitions (/dev/cciss/c0d0p1 - p7) PING asks me where to restore from and lists the partitions on my disks.

I have both a SCSI and IDE DVDROM to choose from (/dev/hda and /dev/sr0) that the CD can boot from, but ... it can't find the devices to restore the images from.

any help much appreciated
David

That is actually a bug in the coding. When PING looks for an image on the CD drive, it looks for SDA and IDE images not cciss. You could edit the rc.ping file to reflect your setup then re-burn a disk. Got to love DVD-RW

[david.steele]

So something like

Code: Select all

LOG("* Looking for a possible CD/DVD...\n");

my $CD_Dev = '';
{
    my $nb = 0;
    foreach my $d ("hda", "hdb", "hdc", "hdd", "sda", "sdb", "sdc", "sr0", "sr1")
    {
        system("umount /mnt/cdrom >/dev/null 2>&1");
        system("mount /dev/$d /mnt/cdrom >/dev/null 2>&1");
        my $nb = `df|grep cdrom|wc -l`;
        if($nb > 0)
   {
            LOG("  Found and mounted a CDRom\n");
            opendir(DIR, "/mnt/cdrom");
            my(@Files) = readdir(DIR);
            closedir(DIR);
            foreach my $F (@Files)
       {
                if(($F =~/^[hs]d[abcde]$/) || ($F =~/^cciss$/) || ($F =~/^ida$/)|| ($F =~/^rd$/) )
      {
                    LOG("  Found a [/mnt/cdrom/$F] image\n");
          $CD_Dev = $d;
                    $SRC = "/mnt/cdrom";
          LOG("  Linking [/dev/cdrom] to [/dev/$d]\n");
          system("rm -f /dev/cdrom; ln -sf /dev/$d /dev/cdrom");
                }
            }
            sleep(5);   # Blink & start up.
            last;
        }
    }
    unless($nb)
    {
        LOG("  No CDRom device or media was found.\n");
    }
}


[Curtis8]

yes, something like that.

I too got into this problem following the directions in the HOW TO. Running Windows XP and trying to make a Restore DVD.

where do I create the rc.ping file? Does the example need to be changed to reflect which Drive I am using for the boot up on DVD.

In my case I have a SATA & IDE DVD-RW.

thanks.

Plz, guys, help! I'm not getting it very well.
Would it be sufficient to put rc.ping file with this code in root directory of DVD to do the trick?

[Curtis8]

Why not just edit the isolinux.cfg with the commands in the APPEND line? It works the same way as the PXE and syslinux counterparts. There is no need to edit the ping.conf file anymore. It is from a time before the kernel arguments were added in and kept only to make it easier for a sys admin to continue doing things 'the old way'.

[theopract]

I'm total newbie. Will it work like this if I'll add it to isolinux.cfg?

{
system("umount /mnt/cdrom >/dev/null 2>&1");
system("mount /dev/$d /mnt/cdrom >/dev/null 2>&1");
my $nb = `df|grep cdrom|wc -l`;
if($nb > 0)
{
LOG(" Found and mounted a CDRom\n");
opendir(DIR, "/mnt/cdrom");
my(@Files) = readdir(DIR);
closedir(DIR);
foreach my $F (@Files)
{
if(($F =~/^[hs]d[abcde]$/) || ($F =~/^cciss$/) || ($F =~/^ida$/)|| ($F =~/^rd$/) )
{
LOG(" Found a [/mnt/cdrom/$F] image\n");
$CD_Dev = $d;
$SRC = "/mnt/cdrom";
LOG(" Linking [/dev/cdrom] to [/dev/$d]\n");
system("rm -f /dev/cdrom; ln -sf /dev/$d /dev/cdrom");
}
}
sleep(5); # Blink & start up.
last;
}
}
unless($nb)
{
LOG(" No CDRom device or media was found.\n");
}

Portion can not be in the isolinux.cfg file. That will not work. That chunk of code goes into the rc.ping file which is compressed into the initrd.gz file. If you are unsure how to update the rc.ping file there are instructions here on the forum. Other than that you have two options I can see:
1) Wait until Natan releases the newer PING with the fix applied
2) Ask someone on the forum to update the initrd.gz file and send it back to you.

Hi there,
I'm not sure everyone here came with the same issue. I'm wishing to release a new version of PING before 2010
What should be added exactly concerning CCISS devices ?
Thanks !!

Hello, Natan!
Nice to see you on this thread =) We all want CCISS devices images to be visible on a bootable CD/DVD.
For now PING could not see/find CCISS images on a bootable CD/DVD.

[Natan]

Thanks ! Fine for me.

[theopract]

Thanks ! Fine for me.

Hello, Natan!

I'v tried new version of PING (3.00.04 2010) and was hoping to be able to see CCISS images on a DVD, but instead I got into a red screen (see attachment).
Could it be cause of configuration of isolinux.cfg? Though previous version loaded with this configuration, but didn't see CCISS.
