| - | These machines are configured in DHCP to receive ''/var/lib/tftpboot/grub/grub-x86_64.efi'' from the Cobbler host when PXE booting. I had trouble PXEing using BIOS mode on these machines so we're using UEFI. | + | These PXE using Legacy/BIOS mode and can be provisioned via Cobbler normally. |
| - | + | ||
| - | Our usual cephlab_rhel.ks kickstart is not set up to do UEFI so Anaconda will stop and say the Storage Configuration needs editing. | + | |

| - | There is an ansible module that is supposed to allow you to create bonds but it requires NetworkManager-glib which isn't in CentOS8. So I found and used https://github.com/linux-system-roles/network. | + | |

| - | The QFX5200 serving the Officinalis lab goes down on a regular basis. This table will keep track of dates and tickets. | + | |
| - | ^ Date ^ Ticket | Notes | | + | The 100Gb connection is the only uplink for now. The top-of-rack switch in that rack probably has capacity if we need a 1Gb uplink and reserve the 100Gb NIC for backend traffic. |
