[-- Attachment #1 --] Hi all, In the /boot/defaults/loader.conf are these options for memory disk settings: #mdroot_load="YES" # The "mdroot" prefix is arbitrary. #mdroot_type="md_image" # Create md(4) disk at boot. #mdroot_name="/boot/root.img" # Path to a file containing the image. #rootdev="ufs:/dev/md0" # Set the root filesystem to md(4) device. But - is this example for rootdev option still right? Because “ufs:/dev/md0” works fine on freebsd 12.1, but on freebsd 12.3 this does not work and generates error message: Can’t determine root device When I use this option with value “/dev/md0” or “md0” (even with this option commented out), so the machine boots correctly without any error. — Mira [-- Attachment #2 --] <html><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8"></head><body style="word-wrap: break-word; -webkit-nbsp-mode: space; line-break: after-white-space;" class="">Hi all,<div class=""><br class=""></div><div class="">In the /boot/defaults/loader.conf are these options for memory disk settings:</div><div class=""><br class=""></div><div class=""><div style="margin: 0px; font-stretch: normal; line-height: normal; font-family: "Helvetica Neue";" class="">#mdroot_load="YES" # The "mdroot" prefix is arbitrary.</div><div style="margin: 0px; font-stretch: normal; line-height: normal; font-family: "Helvetica Neue";" class="">#mdroot_type="md_image" # Create md(4) disk at boot.</div><div style="margin: 0px; font-stretch: normal; line-height: normal; font-family: "Helvetica Neue";" class="">#mdroot_name="/boot/root.img" # Path to a file containing the image.</div><div style="margin: 0px; font-stretch: normal; line-height: normal; font-family: "Helvetica Neue";" class="">#rootdev="ufs:/dev/md0" # Set the root filesystem to md(4) device.</div></div><div style="margin: 0px; font-stretch: normal; line-height: normal; font-family: "Helvetica Neue";" class=""><br class=""></div><div style="margin: 0px; font-stretch: normal; line-height: normal; font-family: "Helvetica Neue";" class=""><br class=""></div><div style="margin: 0px; font-stretch: normal; line-height: normal; font-family: "Helvetica Neue";" class="">But - is this example for rootdev option still right?
