iPXE stalls during HTTP ISO Boot when accessing an LACP connected server.
Pretty much as the title says:
In my home lab, I have an LACP-Capable switch (HP Procurve J9028B), which has a webserver which has a pair of interfaces configured for LACP. The corresponding switch ports are also configured for LACP. When I SANBoot an ISO larger than about 200MB (which has an embedded ISOLINUX/mboot.c32 boot kernel) I get an odd slowdown, which finally grinds to a halt... a bit of patience revealed this to be a pause of about 90-300 seconds (several times, depending on the image size) during the boot. The boot never fails, but it pauses in the exact same spots each time. The stall occurs during the "append" sequence in the isolinux.cfg file. This slowdown/stall does not occur on a non-LACP Interface, nor from a Virtual running on an LACP-connected Physical Host. Very Curious. Where to begin with troubleshooting this beast? I've even gone so far as to break the LACP Team on the Webserver - the problem goes away when I do. TIA, Matt "Thus far, you have been adrift within the sheltered harbor of my patience..." |
