“/var/cache/fscache”目录过大

配置文件是/etc/cachefilesd.conf

stop cachefilesd服务

[root@wds020 I03nfs]# service cachefilesd status
cachefilesd (pid  3986) is running...
[root@wds020 I03nfs]# 
[root@wds020 I03nfs]# service cachefilesd stop
Shutting down cachefilesd:                                 [  OK  ]
[root@wds020 I03nfs]# service cachefilesd status
cachefilesd is stopped
[root@wds020 I03nfs]#

目前仅停止了cachefilesd服务，下面暂时未做

# 找一个空间足够的分区，创建一个cache目录
[root@wds020 ~]# cd /local_data
[root@wds020 local_data]# mkdir cache

# 将原来cache目录下的内容拷贝到新建的cache目录中
$ cp -ar /var/cache/fscache/cache/*  /local_data/cache/

# 将原来的cache目录删除
$ cd /var/cache/fscache/
$ rm -rf cache

# 在/var/cache/fscache/目录下创建软连接，指向新建的cache目录
$ ln -s /local_data/cache  /var/cache/fscache/cache

先使用cache下的一个子目录@c4实操测试

[root@wds020 I03nfs]# pwd
