It seems like it would be easier to just restore the image to a client, but I had to find a way.

All of this is done on Debian 7 and like Wayne I would not advise you doing this on your production server.

Breakdown:
Install ntfs-3g, partclone, and pigz
Decompress image and restore to a file
Mount image

apt-get install ntfs-3g partclone pigz
cd /images/SecurityE420s/
cat d1p2.img | pigz -d -c | partclone.restore -C -s - -O d1p3.img
mount -t ntfs-3g d1p3.img /mnt

The only way I could find to clear it was through the database.

You could use the event scheduler to automatically clear the table.

Here’s what I came up with to remove completed tasks older than a month.

USE fog;
CREATE EVENT clear_snapinTasks
ON SCHEDULE AT CURRENT_TIMESTAMP + INTERVAL 1 MONTH
DO
DELETE FROM fog.snapinTasks WHERE stCompleteDate < DATE_SUB(NOW(), INTERVAL 1 MONTH);

If you add this to your PXE configuration it should work.

Change x.x.x.x to the FOG IP Address.

MENU COLOR TITLE        1;36;44    #ffffffff #00000000 std

Found this thread on the iPXE forums.

No idea if this will help but all files were built with debugging enabled and latest commit as of today. It will also drop you into the shell on dhcp failure.

tftpboot.tar.gz

The ISO in this thread should still work: https://forums.fogproject.org/topic/4782/help-usb-boot-fog/27

You can write it to your USB drive with dd if=ipxe.iso of=/dev/sdb bs=4M Just replace sdb with your drive.

@maveriick

The package is subversion on Debian.

sudo apt-get update && sudo apt-get install subversion

Do you have other E6540s that work?

I have had this issue with some Lenovos in the past. Updating the BIOS and resetting to defaults usually fixes it, but when it doesn’t we’ve had to replace the NIC.

cml

No idea if this is the best way, but it seems to be working. I’ll let y’all know when it finishes compressing.

for f in *.img; do mv "$f" "${f%.img}-bak.img"; done
for f in *bak.img; do pigz -d -c $f | pigz -9 > "${f%-bak.img}.img"; done

Here is the ipxe files built with debugging, it also exits to shell instead of rebooting.

What about something like this?

Showing I have duplicate values.

mysql> select * from globalSettings where settingKey="FOG_TFTP_PXE_KERNEL";

Dropping duplicates.

mysql> ALTER TABLE globalSettings DROP INDEX SettingKey;

Showing the duplicate is now gone.

ipxe.iso

I got it working with this iso.

ipxescript:

#!ipxe
echo -n Please enter tftp server: && read next-server && goto netboot
:netstart
dhcp && goto netboot || goto netstart
:netboot
ping -c 1 ${next-server} || goto netstart
chain tftp://${next-server}/default.ipxe || shell

cml

One thing you can try is sending the packet from the command line with wakeonlan

wakeonlan 28:D2:44:0C:D9:9B
Sending magic packet to 255.255.255.255:9 with 28:D2:44:0C:D9:9B

Do you have wireshark? If so set the filter to wol and see if you get a packet, if not your switches may be blocking it.

Here were the relevent Cisco commands I had to set on our 4500:

***fogserver vlan***
interface Vlan2					
 ip helper-address 10.2.255.255
!
***high network vlan***
interface Vlan1					
 ip helper-address 10.1.0.119
 ip directed-broadcast 101
!
ip forward-protocol udp echo
ip forward-protocol udp discard

access-list 101 permit udp host 10.1.0.119 any eq echo
access-list 101 permit udp host 10.1.0.119 any eq discard

Could you try this in mysql?

SELECT taskID,taskName FROM tasks WHERE taskStateID=1;

@Sebastian-Roth

Good catch, the post has been modified.

I have built the ipxe files with debug options turned on. This may give more insight into what is going on.

tftpboot.tar.gz

No idea if this helps, but this undionly.kpxe will point to 192.168.1.20. If this works it would seem that your default gateway is being set as next-server.

@Wayne-Workman

It looks like portmap switched to RPC for Ubuntu.

RPC status:
sudo service rpcbind status

Restart RPC:
sudo service rpcbind restart

Enable RPC on boot:
update-rc.d rpcbind defaults

Is there anything in the apache error log?

Debian/Ubuntu: /var/log/apache2/error.log
Red Hat/Centos/Fedora: /var/log/httpd/error_log

I have a similar issue with one model of Dell laptops and solved it using this undionly.kpxe

Debug is enabled on dhcp and tftp and the script drops to a shell if it fails to tftp, for further troubleshooting.

The only modification is with the ipxescript:

#!ipxe
:netstart
dhcp && goto netboot || goto netstart
:netboot
ping -c 1 ${next-server} || goto netstart
chain tftp://${next-server}/default.ipxe || shell

And here are all to pxe files created with that script. pxe-files.tar.gz

–EDIT–

Forgot to include my issue that this solves.

We have Dell Inspiron 11z laptops that fail to get a DHCP address the first time iPXE issues the command. If the DHCP command is sent right after if succeeds and everything works normally.
