Pretty much every time I install Gentoo I hit a new minor issue that requires my attention. Sometimes its caused by a new version of a particular package, sometimes I’ve simply forgot to configure something correctly. Either way, here is an on-going list of issues that I’ve faced after a new installation.
Networking Interfaces Renamed
The networking interfaces were renamed from eth0 to enp10s0 and enp09s0. While this did not make any difference as to whether or not they work, it is annoying!
storm ~ # ifconfig enp10s0: flags=4163
mtu 1500 inet 192.168.111.4 netmask 255.255.255.0 broadcast 192.168.111.255 inet6 fe80::223:8cff:fe7b:5f0g prefixlen 64 scopeid 0x20 ether 00:23:8c:7b:5f:0g txqueuelen 1000 (Ethernet) RX packets 2161 bytes 226082 (220.7 KiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 96 bytes 16270 (15.8 KiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 enp9s0: flags=4099 mtu 1500 ether 00:21:7c:7b:60:ff txqueuelen 1000 (Ethernet) RX packets 0 bytes 0 (0.0 B) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 0 bytes 0 (0.0 B) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
To fix, just run the following command (as root) and then reboot.
storm ~ # touch /etc/udev/rules.d/80-net-name-slot.rules
RAID Devices Renamed
The RAID devices work renamed from
/dev/md128. Again they work, but quite annoying!
If you are affected by this issue (and it bothers you), you may need to alter your
/etc/mdadm.conf file to include a map between the UUID and the device name. In which case you first need to make a note of the UUID, which you can find with
mdadm --detail /dev/md126 and then add an entry similar to the below.
Obviously you need to make sure the right UUID matches the right device name!
ARRAY /dev/md0 uuid=bffb1668:11863a10:bf3af795:0aa37b76
ARRAY /dev/md1 uuid=147ec32e:2721ff1a:3769d3d6:285e5546
ARRAY /dev/md2 uuid=0a3417f5:885e6352:c56063cf:7cc765e3
You may also need to edit the
And add the following if needed.
You still need to run the following. Pay close attention to the output to make sure it is picking up and using the
genkernel --lvm --mdadm initramfs grub2-mkconfig -o /boot/grub2/grub.cfg reboot
Hopefully that worked! If you get strange output from
watch cat /proc/mdstat, make sure you give it long enough time to sync.
