raid5/6劝退

个人经验

1.RAID5/6 如同泡水的卫生纸, 出了问题的时候碎得渣, 很难救.

2.仅次于比RAID0安全一点点,安全性低于RAID1

3. RAID5/6掉盘或者迁移主机, 恢复慢导入硬盘慢容易崩.

4.RAID50 RAID60 没用过不评价.

最后总结: 一块盘或者一块以上, 数据无所谓要空间和速度组RAID0就无所谓;

两块盘要安全首选RAID1, 低成本安全储存方案;

只有三块硬盘的时候建议追加一块, 跨入最低门槛用四块硬盘直接组RAID10, 兼顾安全和速度以及一半硬盘的容量,

换阵列卡或者迁移到其他机箱, 导入快rebuild同步快, 掉了一块盘即使跑半年也不用担心坏.

超微和AMI的IPMI web端进行远程操作开关电源的一些数据

首先是超微的一些资料

获取登陆信息的数据

SESSION_ID=$(curl -s "http://${IPMI_HOST}/cgi/login.cgi" --data "name=${IPMI_USER}&pwd=${IPMI_PASS}" -i | awk '/SID=[^;]/ { print $2 }')
TOKEN=`curl -s "https://${IPMI_HOST}/cgi/url_redirect.cgi?url_name=sys_info" -H "Cookie: ${SESSION_ID}" --insecure |grep CSRF_TOKEN  |  cut -d\" -f 4`

#rest bmc
curl "https://${IPMI_HOST}/cgi/BMCReset.cgi?time_stamp=Thu%20Sep%2011%202014%2017%3A07%3A02%20GMT-0500%20(CDT)&_="  -H "CSRF_TOKEN:$TOKEN;"    -H "Cookie: ${SESSION_ID}" --insecure  -I


#电源操作
curl "http://${IPMI_HOST}/cgi/ipmi.cgi" -H "CSRF_TOKEN: $TOKEN" -H "Cookie: $SESSION_ID" -H "Referer: http://${IPMI_HOST}/cgi/url_redirect.cgi?url_name=man_chassis" --data 'GET_POWER_INFO.XML=(0%2C0)' --insecure

#必须要带TOKEN 带 Referer url_name=man_chassis才能操作电源

操作电源选项接口信息 (抓取地址https://xxxxx.xxxx.xxx/cgi/url_redirect.cgi?url_name=man_chassis)

          url    = '../cgi/ipmi.cgi';
            pars   = '?SET_POWER_INFO.XML=(1,0)&time_stamp=' + (new Date ());

xenserver磁盘xva转raw

官方下载没了http://datahack.se/datastore/xvatool/xvatool-1.1.tar.gz ,只能从github上克隆.

 原文出处https://docs.onapp.com/mg/migration-from-xenserver

yum install make git gcc
git clone  https://github.com/mindo/xvatool
cd xvatool
cmake .
make
make install

安装后就可以解压tar后开始合并文件变成raw了.

cd /tmp
mkdir /tmp/VM1
tar -xf vm1.xva -C  /tmp/VM1
chmod -R 755 VM1
xvatool -p disk-export VM1/Ref\:X/ disk.raw 

frpc指定出口IP

由于frp客户端没有指定出口网卡或者ip设置

只能临时解决方案

useradd -s /sbin/nologin  frp
IP=出口IP
UserID=`id -u  frp`
iptables -t mangle -A OUTPUT -m owner --uid-owner $UserID -j MARK --set-mark $UserID
iptables -t nat -A POSTROUTING -m mark --mark $UserID -j SNAT --to-source $IP

用iptables绑定uid指定出口IP

#这里假设frpc配置文件名为xxbb.ini
sed -i 's/User=nobody/User=frp/g'    /usr/lib/systemd/system/[email protected]
 systemctl daemon-reload
 systemctl enable [email protected]
 systemctl restart [email protected]

重启后ps aux|grep frp 查看进程启动用户是frp就成功了

ipxe安装系统踩坑笔记

时间久了怕记不住, 还得写文本

esxi的 boot.cfg要把/斜杠剔除掉, 才能ipxe安装

xenserver安装引导内核没有dns参数, ipxe的源地址只能ip地址不能用域名.

或者xenserver版本信息在iso目录下的 .treeinfo 文件里面

# cat .treeinfo
[platform]
name = XCP
version = 2.4.0

[branding]
name = XenServer
version = 7.3.0

[build]
number = release/inverness/master/15

[keys]
key1 = RPM-GPG-KEY-XS-7-LCM
key2 = RPM-GPG-KEY-XS-7
key3 = RPM-GPG-KEY-Platform-V1

windows识别iso需要wimtools

命令

#wiminfo  sources/install.wim  | grep -vE "Boot|Description"|grep -A2 "Index:"|awk -F: '{print $2 }'|sed 's/[\t ]\+/ /g'
