It was mentioned in an earlier post:

@george1421 said in Wiping HD:

@lostitguy We you will need to make up your own fog ipxe menu to specifically call the wipe function.

I am not 100% sure I have the stanza right but it should look like this

Menu Item: fog.wipeit
Description: FOG builtin Disk Eraser Tool
Parameters:
kernel tftp://${fog-ip}/bzImage
initrd tftp://${fog-ip}/init.xz
imagargs bzImage initrd=init.xz root=/dev/ram0 rw ramdisk_size=256000 ip=dhcp web=${fog-ip}/fog/ consoleblank=0 loglevel=4 mode=wipe wipemode=full
imgfetch init.xz
boot ||
goto MENU
Menu Show with: All Hosts

I was trying this today. As things likely changed since this was posted I found that I needed to change:

kernel tftp://${fog-ip}/bzImage
initrd tftp://${fog-ip}/init.xz

With :

kernel http://${fog-ip}/fog/service/ipxe/bzImage
initrd http://${fog-ip}/fog/service/ipxe/init.xz

Also there was a ram error so needed to increase size of the ramdisk to something larger such as 512000

I also omitted imgfetch init.xz and it still worked to my understandimg. Can someone please confirm that this line is redundant?

I get a database failed to update after the wipe. I am assuming this is because the wipe was initiated without being tasked?

Also I was surprised that the full wipe on the nvme SSD took less than a minute. Shouldn’t it take much long to write zeros or does FOG wipe perform some other type of erasure? If so what kind of erase method does FOG use for wipemode=full ?
