I’m having a problem with some of my FOG nodes. I’ve updated my custom CA certificate and wanted to issue it to my storage nodes, which have been working without any problems for around a year now, after changing the required files, restarting the apache2 service, and recompiling the iPXE binaries it suddenly stopped working.

I am able to boot with UEFI, but BIOS hangs on “… free base memory after PXE unload”. Tried various files (undionly.kpxe, .kkpxe, ipxe.kpxe), but no luck.

Screenshots from two different storage nodes, the latter of which has not been updated (and works). Same VM, nothing apart from the VLAN tag changed in between:

Thank you for all the help in advance.

@george1421 thanks for the answer

Is there a way to upload an image created by CZ into FOG?

it does not work when I unicast to it either

@george1421 yes, the target computer is on a different subnet than the FOG server however it works if it doesn’t go through this one specific switch (it has multicast configured properly)

forgot to include the photo

Hello, I have a T2600G-28MPS 4.0 switch with multiple VLANs and multicast setup. However, when I try to download an image through it the program terminates at mounting NFS and throwing connection timed out, it only fails this specific thing, all other info is being transferred correctly. It works fine on other switches (MikroTik & Cisco) and I really have no idea what to do

@jas777 nevermind, turned out to be a TP-Link switch not multicasting properly for some reason, everything works now!

@george1421 so I’ve done everythinf that you’ve said would help and I’m faced with a connection timed out on mounting the images. The /proc/cmdline shows that the storage is set to my.servers.ip.addr:/zfs/images/dev

@george1421 thanks for the tip

@jas777 nevermind, the installer just crashed on restarting VSFTPD cause I have it in standalone mode, it created the exports correctly. Will let you know if it works on monday!

@george1421

I’m not sure if it should look like that

@george1421 okay, and is there any way to have the images in a subdirectory of /zfs (/zfs/images) or do I have to dedicate a whole partition/device to it?

Hello,

I wanted to move my /images directory to /zfs/images and unfortunately, I didn’t think much about it and just moved the files manually and changed the path in the default storage unit.

Now it’s throwing that it cannot mount /images/dev on /zfs/images because of some permissions missing. Is there any way to fix it?

Thanks in advance!
