I’m upgrading moaxcp/gentoo64 and these are my notes.
emerge --sync and
emerge -avuND @world I found that gentoo release a new kernel (4.0.5). I followed this to upgrade making sure to use –lvm. I added a new script /root/buildkernel.sh which will build the kernel with the correct options. I made sure to remove the old kernel to save space.
There is a script cleanup_diskspace.sh which will remove some files and make the .box file smaller when it is built.
When I originally created the vm I used lvm and made the root partition 7GB. Now is the time to resize it to something more useful. I changed the disk size to 120GB using
VBoxManage modifyhd gentoo-vagrant.vdi --resize 122880
LVM was not installed on the system even though the modules are in the kernel. When installing lvm there was an error related to this thread. The advice on the thread is to remove parallel compilation by setting MAKEOPTS="-j1". After this change boost still did not compile. I added the ~amd64 keyword for dev-libs/boost to pick up a newer package. Even then I still had errors.
The problem with parallel compilation is the amount of memory used. I increased the memory and got a different error. This time the error is No space left on device.
df -h Filesystem Size Used Avail Use% Mounted on udev 10M 4.0K 10M 1% /dev /dev/mapper/vg0-root 6.8G 4.5G 2.0G 70% / tmpfs 201M 388K 201M 1% /run shm 1005M 0 1005M 0% /dev/shm cgroup_root 10M 0 10M 0% /sys/fs/cgroup
This shows root as only 70% full but checking the inode count I get
df -i Filesystem Inodes IUsed IFree IUse% Mounted on udev 256513 409 256104 1% /dev /dev/mapper/vg0-root 458752 458745 7 100% / tmpfs 257103 355 256748 1% /run shm 257103 1 257102 1% /dev/shm cgroup_root 257103 4 257099 1% /sys/fs/cgroup
This makes me want to rethink the entire gentoo64 build. I shouldn’t have to use lvm and I’m not sure why I installed it. I think I’m going to rebuild the whole system without lvm and make a larger hard drive.
