Linux Disk Occupation 100% workaround

The/OPT partition is full of web logs, causing some services to not function properly, so rm-fr off these logs (nearly 11GB), but the service is still not back to normal, with DF-HT, the partition occupies or 100%:

[[email protected] opt]# df-ht file system type capacity used available% mount point/dev/sda9 ext3 996M 228M 717M 25%//dev/sd  A10 ext3 27G 12G 14G 47%/var/dev/sda8 ext3 996M 34M 911M 4%/home/dev/sda7 ext3 2.0G 36M     1.9G 2%/temp/dev/sda6 ext3 3.0G 2.6G 228M 92%/usr/dev/sda3 ext3 19G 19G 0 100%/opt/dev/sda1 Ext3 99M 12M 83M 12%/boottmpfs tmpfs 2.0G 0 2.0G 0%/dev/shm

But with the du-sh/opt command, see:

[email protected]/]# du-sh/opt/8.3g/opt/

These files should be deleted, but the space is not released, of course, the restart can be resolved, but will cause all the business disruption on the server, you can use the following command to view the deletion of file occupancy:

[[email protected] opt]# lsof |grep deletemysqld_sa 11317      root  cwd       DI R        8,6          0     102107/usr/local/mysql (deleted) mysqld _sa 11317      root  255r      reg        8,6      1 3620     102182/usr/local/mysql/bin/mysqld_safe (deleted) mysqld    11353     MySQL  t XT       REG        8,6   29382763     102138/usr/local/mysql/bin/mysql D (deleted) mysqld    11353     MySQL    5u      reg       &NBS p;8,9          0      58761/TMP/IBPFBHSA (deleted) mysqld    11353 &nbsp ;   MySQL    6u      reg        8,9          0 &N Bsp    58771 /tmp/ibqomnag (Deleted) mysqld    11353     MySQL    7u      reg   &NBSP ;    8,9          0      58772/TMP/IBN4C4RL (deleted) mysqld     11353     MySQL    8u      reg        8,9       &NBS P  0      58781/TMP/IBKWP8ZR (deleted) mysqld    11353     MySQL   12u   & nbsp  reg        8,9          0      58782/TMP/IBNQRZSX (dele Ted) Java      16961      root    1w      reg       & nbsp;8,3 5822263296     457562/opt/tomcat/logs/catalina.out (deleted) Java      16961   &NB Sp  root    2w      reg        8,3 5822263296     457562/opt/tom Cat/logs/cAtalina.out (Deleted) Java      16961      root   12w      reg   &NB Sp    8,3 5469261824     197191/opt/tomcat/logs/catalina.2013-01-02.log (deleted) Java     & nbsp;16961      root   13w      reg        8,3    2166784     197192/opt/tomcat/logs/localhost.2013-01-02.log (deleted) Java      16961     &NB Sp;root   14w      reg        8,3          0   &NBSP ; 391681/opt/tomcat/logs/manager.2013-01-02.log (Deleted) Java      16961      root   15w      reg        8,3          0     391682/OPT/T Omcat/logs/host-manager.2013-01-02.log (Deleted)

You can see that these files are deleted, but still occupy space, and now just kill the processes:

[[email protected]/]# kill-9 16961[[email protected]/]# df-ht file system type capacity used available% mount point/dev/sda9 ext3 996M 228M 717M 25%//dev/sda10 ext3 27G 12G 14G 47%/var/dev/sda8 ext3 996M 34M 911M 4%/ho     ME/DEV/SDA7 ext3 2.0G 36M 1.9G 2%/temp/dev/sda6 ext3 3.0G 2.6G 228M 92%/usr/dev/sda3 ext3 19G 8.4G 9.6G 47%/opt/dev/sda1 ext3 99M 12M 83M 12%/boottmpfs tmpfs 2.0G 0 2.0G 0%/dev /shm

Problem solved, the service also resumed finishing ...
