Re : Multicast randomly hangs

Hi,

Thanks to Felipe Solari

We managed to deploy a multi partition image with multicast.
We just add a sleep 5 to the fog.download at the line 440.

• unzip init.xz (the same goes for init32.xz) with xz -d init.xz
• mount the init file in a loop device with: mount -o loop init sometempdir/
• go to sometempdir/bin with cd
• edit fog.download
• save your file, and back to the init file dir.
• zip it with xz -C crc32 init

 elif [ "$imgType" == "mps" ]; then
                        dots "Checking Hard Disks";
                        runPartprobe $hd &> /dev/null;
                        echo "Done";
                        parts=`fogpartinfo --list-parts $hd 2>/dev/null`;
                        diskLength=`expr length $hd`;
                        for part in $parts; do
                                partNum=${part:$diskLength};
                                echo " * Processing Partition: $part ($partNum)";
                                imgpart="$imagePath/d1p${partNum}.img*";
                                sleep 2;
                                if [ ! -f $imgpart ]; then
                                    echo " * Partition File Missing: $imgpart";
                                    # Add a sleep here
                                    sleep 5;
                                else
                                    writeImage "$imgpart" $part;
                                fi
                                resetFlag $part;
                        done

Hope this help.
Thanks for Fog It’s a great soft.

@marcolefo I am not sure if I get what you are up to with this. You posted a supposed fix for FOG version 1.2.0 which is years old in the bug reports section of this forum. Please don’t get me wrong, I don’t want to offend you for posting this. I just don’t understand it - partly because there are two sleeps in the code you posted, one sleep 2 which might solve the issue your talk about and another sleep 5 which is in the “wrong” if-branch and won’t help in getting multicast right from my point of view.

Would you mind correcting the code and/or your comment so that other people still using FOG 1.2.0 can profit from this?

Moving this to Tutorials section of the forum…

No problem. Excuse me for the wrong forum ;).

Adding the sleep 5 solved our problem. The sleep 2 was already here unless I am mistaken.

@marcolefo The sleep 5 you’ve added will only happen if the $imgpart is not found. This seems rather pointless if you ask me. (Again following along @Sebastian-Roth I’m not intending to offend, but why does having sleep 5 in a spot where no code is run to begin with “help” a user with multi partition imaging via multicast?
