我有一台来自 OVH 的服务器，并按照以下步骤在 OVH 服务器上的 FreeBSD10 上设置 ZFShttps://wiki.freebsd.org/RootOnZFS/GPTZFSBoot/Mirror
创建可启动的 ZFS 文件系统
zpool destroy zroot
gpart destroy -F ada0
gpart destroy -F ada1
gpart create -s gpt ada0
gpart create -s gpt ada1
gpart add -b 34 -s 64k -t freebsd-boot ada0
gpart add -s 8G -t freebsd-swap -l swap0 ada0
gpart add -t freebsd-zfs -l disk0 ada0
gpart add -b 34 -s 64k -t freebsd-boot ada1
gpart add -s 8G -t freebsd-swap -l swap1 ada1
gpart add -t freebsd-zfs -l disk1 ada1
gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 ada0
gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 ada1
创建 ZFS 池 zroot
mkdir /tmp/zroot
zpool create -o cachefile=/boot/zfs/zpool.cache -m none -f zroot mirror /dev/gpt/disk0 /dev/gpt/disk1
zpool set bootfs=zroot zroot
zfs set checksum=fletcher4 zroot
zfs set mountpoint=/tmp/zroot zroot
zfs create -o compression=on -o exec=on -o setuid=off zroot/tmp
安装 FreeBSD 到 ZFS 文件系统
zfs create -o compression=on -o exec=on -o setuid=off zroot/tmp
chmod 1777 /tmp/zroot/tmp
zfs create zroot/usr
zfs create zroot/var
zfs create -o compression=lz4 -o exec=off -o setuid=off zroot/var/crash
zfs create -o exec=off -o setuid=off zroot/var/db
zfs create -o compression=lz4 -o exec=on -o setuid=off zroot/var/db/pkg
zfs create -o exec=off -o setuid=off zroot/var/empty
zfs create -o compression=lz4 -o exec=off -o setuid=off zroot/var/log
zfs create -o compression=gzip -o exec=off -o setuid=off zroot/var/mail
zfs create -o exec=off -o setuid=off zroot/var/run
zfs create -o compression=lz4 -o exec=on -o setuid=off zroot/var/tmp
chmod 1777 /tmp/zroot/var/tmp
zpool export zroot
zpool import -o cachefile=/tmp/zpool.cache zroot
cd /tmp/zroot
mkdir fileinstall
cd fileinstall

当我重新启动系统时，我无法访问它，并且 OVH 管理屏幕上出现错误，但由于我没有 KVM 访问权限，因此我无法看到错误。
我在这个过程中是否遗漏了什么？
答案1
好的，我错过了“echo 'defaultrouter="XXX.XXX.XXX.254"”，否则一切正常
