收到监控的兄弟报CDN有台服务器的squid启动不起来了.
上去看了下日志
Jun 9 22:37:09 WEBCDN squid[21516]: Squid Parent: child process 21709 started

看了下cache-dir的目录权限是正确的，于是看了下操作记录
发现是有人使用了kill将squid干掉了！
Squid在运行时会写一个swap.state文件，如果强制kill掉squid会导致swap.state文件出现错误，那么squid也就没有办法启动了。
同时看了cache.log
2012/06/09 22:51:30| Store logging disabled

FATAL: storeDirOpenTmpSwapLog: Failed to open swap log.
Squid Cache (Version 1.0): Terminated abnormally.
CPU Usage: 0.018 seconds = 0.006 user + 0.012 sys

Page faults with physical i/o: 0
看了下空间存在，但是inode用完了
已经重新格式化（这个盘格的时候可能出现了问题，没有正常格式化完）：
mkfs.ext3 -N 36634624 /dev/sde1
因此，以后squid发生问题看下/var/log/messages和/log/squid/cache.log，不要使用kill来杀squid.
