rockly linux /dev/mapper/rl-root 100% 已满

Question

我一整天都遇到随机故障，一些 php 脚本说没有足够的空间。我有 1 TB 驱动器，已使用约 200 GB，所以我有足够的空间。我检查了日志和目录似乎一切正常。我该怎么做才能确保这种情况不再发生？

[(01:44 PM)] [(~)] $ df -h
Filesystem           Size  Used Avail Use% Mounted on
devtmpfs              63G     0   63G   0% /dev
tmpfs                 63G  120K   63G   1% /dev/shm
tmpfs                 63G  106M   63G   1% /run
tmpfs                 63G     0   63G   0% /sys/fs/cgroup
/dev/mapper/rl-root   70G   70G  668M 100% /
/dev/mapper/rl-home  856G  121G  736G  15% /home
/dev/nvme0n1p2      1014M  294M  721M  29% /boot
/dev/nvme0n1p1       599M  5.8M  594M   1% /boot/efi
tmpfs                 13G     0   13G   0% /run/user/0

然后当我测试 php 脚本时，这就是我得到的

[(12:14 PM)] [(/home/virtual/sites/)] $ php test.php
Fatal error: Uncaught mysqli_sql_exception: Error writing file '/tmp/MLfd=71' (OS errno 28 - No space left on device) 

这是一些包含最多数据的目录大小
