抓哪个进程干坏事前要先停掉syslog /etc/init.d/rsyslog stop echo 1 > /proc/sys/vm/block_dump dmesg | egrep “READ|WRITE|dirtied” | egrep -o ‘([a-zA-Z]*)’ | sort | uniq -c | sort -rn | head 1423 kjournald 1075 pdflush 209 indexer 3 cronolog 1 rnald 1 mysqld 不要忘记在抓完之后关掉block_dump和启动syslog echo 0 > /proc/sys/vm/block_dump /etc/init.d/rsyslog start (责任编辑：IT) |
