我在新服务器上安装了 Ubuntu 18.04，我需要挂载/var/log到单独的分区。我用 创建了一个新分区，手动挂载它可以正常工作。如果我在启动期间通过 挂载，ext4服务器将无法启动。/var/logfstab

/dev/nvme2n1p1将是目标分区。在启动时安装单独分区的正确方法是什么/var/log？
我的fstab：
/dev/md/0 / ext4 noatime 0 1
#/dev/nvme2n1p1 /var/log ext4 noatime 0 2
/dev/md/1 /home ext4 noatime 0 2
/dev/md/2 /tmp ext4 noatime 0 2
/dev/md/3 /var/www ext4 noatime 0 2
/dev/nvme2n1p2 /var/backup ext4 noatime 0 2
proc /proc proc defaults 0 0
答案1
我必须在 fstab 中使用 UUID。如果没有它们，每次启动时，它都会将 nvme1n1p1 与 nvme2n1p1 交换，反之亦然，因此分区总是很忙，无法挂载。我以前从未见过这样的行为。我使用 UUID 进行了无数次重启，现在它运行正常
