Estou executando o Ubuntu 14.04 em um servidor remoto. É o único sistema operacional instalado. Eu preciso ser super cauteloso antes de reinicializar a máquina, já que o acesso do KVM ao servidor é bastante complicado.
Durante uma atualização do GRUB, perguntam onde instalar o GRUB. Há Raid1 nos discos. Eu não tenho certeza onde eu deveria.
Aqui está a tabela de montagem:
# mount
/dev/md2 on / type ext4 (rw)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw,noexec,nosuid,nodev)
none on /sys/fs/cgroup type tmpfs (rw)
none on /sys/fs/fuse/connections type fusectl (rw)
none on /sys/kernel/debug type debugfs (rw)
none on /sys/kernel/security type securityfs (rw)
udev on /dev type devtmpfs (rw,mode=0755)
devpts on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=0620)
tmpfs on /run type tmpfs (rw,noexec,nosuid,size=10%,mode=0755)
none on /run/lock type tmpfs (rw,noexec,nosuid,nodev,size=5242880)
none on /run/shm type tmpfs (rw,nosuid,nodev)
none on /run/user type tmpfs (rw,noexec,nosuid,nodev,size=104857600,mode=0755)
none on /sys/fs/pstore type pstore (rw)
/dev/md1 on /boot type ext3 (rw)
/dev/md126 on /home type ext4 (rw,noexec,nosuid,nodev)
/dev/md127 on /backup type ext4 (rw,noexec,nosuid,nodev)
systemd on /sys/fs/cgroup/systemd type cgroup (rw,noexec,nosuid,nodev,none,name=systemd)
E aqui está a saída do fdisk:
