晚上在作一个实验克隆硬盘时报错

[jean@jeantoe Web.Mysql.Slave]$ VBoxManage clonehd Web.Mysql.Slave.vdi ~/vm/Cspace/

解决方法为

粗心，proftp和vsftp同时启动”不报错”

由partprobe引发的错误

admin — Mon, 13 Apr 2009 12:40:18 +0000

下午做磁盘的配额的时候报错
quotaon /usr/data6

quotaon: Cannot find quota file on / [/dev/sdc1] to turn quotas on/off.

检查后发现用户配置文件存放在sdc1中。
首先想到的是刚才格式化硬盘后直接用partprobe（实际上我已经都是这么干），莫非是以前运气超好从来不报错？然后重做了一遍，这次不敢partprobe了，老老实实重启。
后来再quotaon时就没问题了。
总结一句话生产系统上最好别用partprobe，不然出了莫名巧妙的错误可有的受了……
