MySQL：添加索引的时候出现错误：1114 – The table ‘xxx’ is full
在对一张大表添加字段的时候，出现如题所示的错误，具体如下：

查看文件系统的空间：
|
1 2 3 4 5 6 7 8 9 |
[root@mysql-pdc0023 mysql]# df -h Filesystem Size Used Avail Use% Mounted on devtmpfs 3.9G 0 3.9G 0% /dev tmpfs 3.9G 0 3.9G 0% /dev/shm tmpfs 3.9G 384M 3.5G 10% /run tmpfs 3.9G 0 3.9G 0% /sys/fs/cgroup /dev/sda1 30G 26G 4.7G 85% / tmpfs 783M 0 783M 0% /run/user/1089 [root@mysql-pdc0023 mysql]# |
当前看似乎是足够的。
但是，如果在执行增加字段的命令的过程中查看的话，就会发现问题：
可以看到，确实是因为空间不够的原因，导致了MySQL抛出错误：1114 The Table ‘xxx’ is full
解法：扩容MySQL数据目录所在的挂载点（MountPoint）
