Linux磁盘100%已用求解答

注:/home由于挂在另外一个磁盘下,所以可以无视。
那在/dev/mapper/cl-root这块盘下大致就用了(29-23=6G)

[root@localhost mysql]# du -sh /
29G

前面这台机器不归我管,后来出了这个问题让我来弄。
经理说,前面这台机器还好好的,有一天重启了一下,然后就发现mysql启动不了了,查看一下磁盘用了100%了,然后就删了一些日志文件,大概清理了2G,然后重启一下,结果重启完又变成100%,清理出来的2G不见了

已尝试:

1)怀疑过中毒了,但是CPU没有异样,就磁盘有问题

2)主要运行的程序有 tomcat,redis,mosquitto
我已经排除了tomcat日志过大的问题,我重启过tomcat,如果过大的话,重启的时候已经没掉了。
redis占用的内存看了下,也不是很大,才百来兆。

3)losf | grep delete 也已经试过了,没发现有什么占用着
因为重启之后磁盘还是满的,也不太可能是什么进程占用着文件没释放

[root@localhost conf]# lsof | grep deleted

4)磁盘坏了~
如果是这种情况,就莫得办法咯。

求大神帮忙~先谢过了。

3个回答

JKL852qaz
林兴洋 应该不关日志的事,tomcat日志/home那个盘,23G里面就包括了tomcat的日志。
一年多之前 回复

5)另外,关于隐藏文件我也查了,隐藏文件没有占太多空间

home里面占用不正常,检查一下大小,怀疑有进程dump太多垃圾

基于snmp4j取得linux系统的cpu、ram信息

sorry,由于传图片比较麻烦,问题请见:http://bbs.chinaunix.net/forum.php?mod=viewthread&tid=4091102&extra= ps:希望做过snmp的大拿能过来解答一下。 菜鸟通过 cat /proc/meminfo 得到linux系统的内存信息: 大家可以看到MemTotal: 2071272KB MemFree:97972KB 下面菜鸟同snmp4j得到的内存信息: 2013-07-17 16:51 上传下载附件 (35.39 KB) 1.3.6.1.4.1.2021.4.5.0 = 2071272 1.3.6.1.4.1.2021.4.6.0 = 97964 1.3.6.1.4.1.2021.4.11.0 = 4259492 具体的OID信息可以看这里:http://blog.sina.com.cn/s/blog_77c854670100qwso.html 给大家截了一个内存信息的OID: 可以看到:Total RAM Free: .1.3.6.1.4.1.2021.4.11.0 Total RAM used: .1.3.6.1.4.1.2021.4.6.0 菜鸟不知为什么会出现矛盾的地方:通过 “cat /proc/meminfo” 得到 MemFree:97972KB,而通过snmp4j得到Total RAM Free:1.3.6.1.4.1.2021.4.11.0 = 4259492,然而却与Total RAM used: .1.3.6.1.4.1.2021.4.6.0 = 97964 大致相同(肯定会有些许不同),不知道这是为什么? 大拿一定会知道的,望解答! 告诉菜鸟一下snmp4j计算cpu,内存,磁盘利用率等一些问题的方法。 谢谢!

curl的输出作为ffmpeg的输入,通过管道如何实现

linux环境下,我要执行两条命令,一条curl从web服务请求数据,另外一条用ffmpeg对请求来的数据进行转码 。简单的方案是,curl请求的数据写出到磁盘,然后ffmpeg再读取。但这会有磁盘io带来时间开销 所以我想要数据操作都在内存中进行。想到的方案是通过管道,curl请求来的数据不写出 直接送给ffmpeg处理。但不知怎么搞,求解答

怎么控制,不让linux下debug信息输出到Tomcat下log/catalina.out

最近维护服务器的时候,发现上传上去的文件大小全部为0, 一查才知道磁盘已经被占满了,排查下来发现tomcat下log/catalina.out文件 竟然达到惊人的10G,观察里面的信息,几乎全部是项目的debug信息, 而项目log4j的配置输出地址日志信息正常,等于是日志信息正常打印到指定位置之后, 又重复打印到catalina.out。 搜了下这个问题,几乎全是如何分割或清空catalina.out的方法, 没有如何控制catalina.out输出的方法。 我现在通过cronolog让每天产生一个catalina.out不让单个文件过大, 但终究不是好的解决办法,请懂的大神解答下,如何配置,catalina.out 才能不打印debug之类的日志。

pm2报错[PM2] Spawning PM2 daemon with pm2_home=/root/.pm2

安卓内部存储空间具体有多大?

提问原因:所有文章都说应该使用外部存储空间(因为比较大)。 提问:内部存储空间具体有多小? 设备:小米8SE, 机身内存64G。 已知条件: 内部存储路径:理论上是根目录/data/data/包名/。 用AndroidStudio的设备文件管理器查看确实是根目录/data/data/包名/。 用getCacheDir().getAbsolutePath()打印出的路径是/data/user/0/包名/cache。 这里我就挺奇怪的(data变成了user/0),希望能顺便帮我解答一下。 外部存储路径:理论上是根目录/storage/sdcard/Android/data/包名。 用AndroidStudio的设备文件管理器查看是根目录/sdcard/Android/data/包名(跟理论上的不太一样)。 用getExternalCacheDir().getAbsolutePath()打印出的路径是/storage/emulated/0/Android/data/包名/cache。 反正都不太一样,但也差不多,可能不同手机厂家都有差异。 动手实践: 实践1:已经写代码尝试确实可以在内部存储目录下 新建文件夹 和 文件(图片,视频)。 实践2:StatFs可以计算出内存相关的数据,我的数据是block大小:4096,block数目:12882803,总大小:49GB。 这里也挺奇怪,手机参数写着64G,用这个算出来是49G。 可用的block数目::1781435,剩余空间:6GB 疑问:谁能给个具体的数据,内部存储目录下放多少文件APP就不能运行了(内部空间具体有多小)。 个人理解:linux我不知道,但是Windows是CDE盘在最开始就确定了,比如C盘100GB,D盘500GB。 我觉得安卓不像Windos一样分盘,而是只有一个盘,大家(内部和外部存储)一起用,只是大家路径不一样,比如我现在手机还剩6G空间,我往内部存储里放5个G文件也是可以正常使用的(这是猜测,没有实践, 很可能是错的)。 求大佬讲一下正确的姿势(顺便吐槽一下好多文章都没有刨根问底的态度呢)。

elipse插件机制咨询。

一直在eclipse-php中使用esftp插件进行传输文件到linux系统, 早几天由于连续按键同时进行上传文件、编译导致eclipse卡死了一次。 现在我只要一使用这个插件eclipse就卡死了,关闭也无法正常关闭。 几天了,没有找到原因。已经尝试的方法: 0、使用微软的监测工具看使用此插件时读取、写入的文件情况 -- 无可用价值文件 1、换一个磁盘重装原始eclipse -- 无效 2、搜索系统内所有esftp关键字相关的文件并进行删除 -- 无效 3、搜索注册表所有eclipse、esftp相关的项进行删除 -- 无效 4、-clean 启动eclipse -- 无效 5、在其他版本eclipse中使用(非PHP版本,另外用来开发安卓和WEB的eclipse) -- 正常 6、查看eclipse日志 -- 无异常输出 ---------------------------------------------------------------------------------- 这个插件对平时开发很有帮助,在线等大神解答。 ! ![图片说明](https://img-ask.csdn.net/upload/201508/27/1440664930_85410.jpg) [图片说明](https://img-ask.csdn.net/upload/201508/27/1440664706_523368.jpg)

MySQL性能优化(五):为什么查询速度这么慢

【高并发】高并发秒杀系统架构解密,不是所有的秒杀都是秒杀!

网上很多的文章和帖子中在介绍秒杀系统时,说是在下单时使用异步削峰来进行一些限流操作,那都是在扯淡! 因为下单操作在整个秒杀系统的流程中属于比较靠后的操作了,限流操作一定要前置处理,在秒杀业务后面的流程中做限流操作是没啥卵用的。

代码注释如此沙雕,会玩还是你们程序员!

某站后端代码被“开源”,同时刷遍全网的,还有代码里的那些神注释。 我们这才知道,原来程序员个个都是段子手;这么多年来,我们也走过了他们的无数套路… 首先,产品经理,是永远永远吐槽不完的!网友的评论也非常扎心,说看这些代码就像在阅读程序员的日记,每一页都写满了对产品经理的恨。 然后,也要发出直击灵魂的质问:你是尊贵的付费大会员吗? 这不禁让人想起之前某音乐app的穷逼Vip,果然,穷逼在哪里都是...

程序员因没转发公司内容,被领导扣500,辞职后:加了三行代码

现如今,程序员在一二线城市可谓是非常的抢手,毕竟年薪那么多,一般在工作了几年之后,程序员想要攒到一套房子的首付是不成问题的,所以一些大龄的女青年在相亲的时候要把程序员当成了首选。但表面上看起来风光的程序员,背地里也受了非常多的委屈,最近有一名程序员没有转发公司的内容到朋友圈被领导扣了500块,当他辞职了之后,却非常淡定。 从个这个帖子中,我们可以看出这名程序员的情绪还是比较激动的,因为没有转发公司的内容到朋友圈,就要被罚款500块,这是非常不合理,换做是别人也不肯接受,而且三次没有转发就要被劝退,这是什么

为什么中国80%的程序员面试造大炮,工作扭螺丝,复制粘贴代码一把梭?

面试造大炮,工作扭螺丝,复制粘贴代码一把梭! 最近无聊和同事无意间聊天,开个玩笑,说我们写的什么代码最多,一位同事说我大部分都是复制粘贴,写什么代码?“我们都是代码的搬运工,都是在重复的写着不同的代码”,哈哈,当时还没有反应过来。 后面想想,其实也是事实,这个玩笑差点毁了我的三观,下面我们简单聊聊。 首先从源头来说,程序员使用语言开发,大部分语言都是相同的,只要熟悉的语言的语法知识,就能做出相应的功能,而很多的功能都是相似的,大致相同。 比如:去年开发了一个社交类项目,里面有用户...
