磁盘挂载问题，求大神指导。。。。（很急啊）
山漫水痕发布于
&&字号: &&&&(网友评论&0&条)&
一个新装的系统，总共有8块盘。sda用来装系统，其他的盘挂载在home分区下面。但是有一块盘老实挂载不上，提示如下错误：
[ ~]# mount -a
mount: wrong fs type, bad option, bad superblock on /dev/sdg1,
or too many mounted file systems
然后我尝试着重新分区并格式化硬盘，用parted命令，然后mkfs.ext4
/dev/sdg1,也还是不行。因为是菜鸟，所以不大会排查错误，dmesg和message里面的信息如下：
[ ~]# dmesg |grep error

如上面dmesg里面的信息显示的，是不是说明sdg出现了比较严重的错误，需要演艺吗？

问题补充：怕大神看不清，来个清楚的。
电脑是11年配的，那会预算有限，整体的配置就是上图这样。现在想把电脑升级一下，想升级一下显卡，但是又不了解现在这个行情。主要是不知道按我现在这个电脑的配置应该升级成什么样的显卡合适，毕竟CPU和主板都是三年前的东西了，怕不兼容，或者说是整体效果对不起这个新换的显卡。而且花很多钱还不能有很好的实际效果，这不是一个悲剧么。现在请求大神帮忙看看，指导一下，我是应该适合怎样选择。是重新配一个机子比较合适呢？还是只升级硬件就可以？我也不知道还有多大的空间可以升级。配机子的预算在3500以下。配显卡的预算.....0-1000元可以接受。元的话如果更值得的话也可以接受。还有就是有什么散热好的机箱推荐一下，我当初选的这个机箱的时候不懂事，只为了好看，现在越用越觉的散热效果很不好，尤其是夏天。。。。真想把机箱放到冰箱里。我平时玩游戏。。。怎么说呢...CF现在是真的玩的很不愉快了，机子刚配好的时候FPS在140左右。现在不到100了。玩LOL有时候也会卡一下，不过不是像CF那么致命的难过。玩梦三也会卡。街头篮球卡我不知道为什么。偶尔玩玩wow，很少玩哪些纯靠显卡的单机游戏。看电影的时候看高清貌似还行，就是拖拽会卡，是不是因为硬盘读取？我现在这个机子已经很对不起我家的网速了。可能我说的这些游戏别人会说对显卡的要求都不是很高。（具体的要求高于不高我也说不清楚，就是我去实体店问的时候哪些店员问我玩什么，我说CF，‘就以CF为例。’他们会那样的看着我，说你至于配那么好的么...额，我就无语了）但是按我现在的实际情况，玩起来就是让你很不爽。比如说ping在20的时候对枪，你已经躲起来了，然后死了。阿西吧。。还有就是，你没看到人，你死了，然后人出来了。。。。不知道这个心态大神们有没有人能理解...我的鼠标、键盘、鼠标垫、耳机之前全是为了玩CF配的。（因为之前很着迷那个游戏）而且现在还有很好的网速。但是现在却成了你没办法驾驭的东西。。。反正这个实际实用状态让我很不爽。以上这个心态的形容我就用CF这个游戏来描述了，因为就是这个游戏给我不好的体验效果最明显。说这么多就是希望大神能明白我这个心情，我就是想合理升级后可以让自己愉快的玩耍。而且我平时用电脑应该说不乱折腾的人。而且比较干净，机箱内基本没有灰，从夏天到现在盖子一直是开着的。我想升级后能用的时间也要有点保证，最起码再玩个几年吧。呃。。想说的大概就是这么多，写了这么多全是走心的言语，希望大神们看到后能理解我这个心情，并给予优秀的指点。在此谢过。
已有1条答案
& & 你的机子可以先使用一两年后再购买新的，处理器推荐上X4 955，二手价格在三四百，显卡可以上GTX750ti，如果预算充足的话再加上SSD就很不错的，这样的性能主流的游戏都没有问题。
追问：GTX750ti？
SSD是什么？
要是换新机子的话我想用下英特尔的CPU呢。主要对这个还是不太懂，不知道那个更合适。
追问：我现在换这个显卡的话怎么样？

电路分析基础题目求大神指导 追加100分 求电路的平均功率P,无功功率Q,视在功率S,功率因数λ

先求总阻抗,和初中电路一样算,只不过用了复数运算Z=（4+j4）//(-j4)+2+(-2j)=6-j6 Ω=6√2∠-45° ΩU=6∠0° VI=U/Z=1/√2∠45° AφU-φI=-45°P=UIcos(-45°)=3 （W） （此式以下式中U,I含义是U,I的模大小,前面U,I是向量,书写时候上面应该加点以区别）Q=UIsin(-45°)=-3 （var）S=UI=3√2=4.243（V*A）λ=cos(-45°)=√2/2=0.707注意P的单位是W,Q单位是var,S单位通常写作V*A
其他类似问题
P叫有功功率，平均功率啥玩意儿看不懂对于原电路进行等效变换后得：j4电感和4Ω电阻串联后与-j4电容并联，并联后再与2Ω，j2电容串联。故总阻抗表示为：Z = 2-j2+[-j4//(j4+4)] = 24/17 - j54/17
（数字有点妖） = √[(24/17)^2 + (54/17)^2] ∠[arctg (4/9...
先求总阻抗：Z=（4+j4）//(-j4)+2+(-2j)
ΩU=6∠0°
V所以电流相量I=U/Z=（1+j)/2复功率S=UI*=6(1-j)/2=3-3j=P+jQ平均功率P等于3W，无功功率Q为-3var,视在功率S=3√2VA；功率因率λ=P/S=0.707
