我在我的服务器上使用 ubuntu，并且只能通过 SSH 进行访问。
我需要添加新磁盘，但无论我怎么尝试都无法做到。希望得到您的帮助：
输出：fdisk -l

因此，正如您所看到的，我有一个 53 GB 的磁盘 xvdb，但如果我写入：
df -h我在那里看不到他：
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/TEST--AudaHistory--vg-root 5.6G 5.0G 274M 95% /
udev 972M 4.0K 972M 1% /dev
tmpfs 399M 204K 399M 1% /run
none 5.0M 0 5.0M 0% /run/lock
none 997M 0 997M 0% /run/shm
/dev/xvda1 236M 32M 192M 14% /boot
我尝试了诸如 mount -l /dev/xvdb1 /var/www 之类的操作，但总是没有任何反应，我只得到了帮助的响应，或者我得到了写入文件系统的响应，如果我使用 ext4 或 ntfs，我只得到自动帮助的响应
有人能帮我吗？PS：我看到到处都有人忘记用这个名字创建目录，我的目录肯定是 /var/www，所以问题出在其他地方 :(
答案1
如果您不是以 root 用户身份执行此操作（我假设您不是），则需要使用 sudo。
它应该很简单sudo mount /dev/xvdb1 /var/www
