为什么不能建数据库

Question

出现错误：

SQL 语句 :  

CREATE DATABASE `aaa`

MySQL 返回：

Can't create database 'aaa'. (errno: 2

是不是哪里设置出现错误？？？

Answer 1

谁能帮我解释一下这篇：

Problem:
Getting error:

fatal lock manager error: Semop failed, errno=28 [-no space left on device]

Solution:
This error is due to running out of semaphores or shared memory.

To resolve this problem increase the InterBase parameters:

version 3:
        SHMSIZE: size of shared memory segments
        SEMCOUNT: number of semaphores InterBase can use (max 12

version 4:
        V4_LOCK_MEM_SIZE: size of shared memory segments
        V4_LOCK_SEM_COUNT: number of semaphores

make sure kernel parameters are high enough:

    SEMMNS: number of semaphores in system (SEMCOUNT+16)
    SEMMNU: number of semaphore undo structures (>;= NPROC)
    SHMMAX: max size of share memory segment (>;=SHMSIZE)

Hi!

(/tmp) perror 28
No space left on device

This means that you are out of disk space.
