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

Jun 9 22:37:09 WEBCDN squid[21709]: storeDirOpenTmpSwapLog: Failed to open swap log.

Jun 9 22:37:16 WEBCDN squid[21872]: storeDirOpenTmpSwapLog: Failed to open swap log.

Jun 9 22:37:16 WEBCDN squid[21516]: Squid Parent: child process 21872 exited due to signal 6

Jun 9 22:37:16 WEBCDN squid[21516]: Exiting due to repeated, frequent failures

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

2012/06/09 22:51:30| Rebuilding storage in /data/squid/cache (DIRTY)

2012/06/09 22:51:30| Rebuilding storage in /data1/squid/cache (DIRTY)

2012/06/09 22:51:30| Rebuilding storage in /data2/squid/cache (DIRTY)

2012/06/09 22:51:30| /data3/squid/cache/swap.state.new: (28) No space left on device

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

Maximum Resident Size: 0 KB

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.
