查看设备类型ID
cat /proc/devices
可以找到rbd设备类型ID编号为252，记住它后接下来在LVM过滤器配置文件中添加它。
修改LVM过滤器配置文件
vim /etc/lvm/lvm.conf
找到types参数，将rbd和252修改为如下配置:
... # Configuration section devices. # How LVM uses block devices. devices { ... # Configuration option devices/types. # List of additional acceptable block device types. # These are of device type names from /proc/devices, followed by the # maximum number of partitions. # # Example types = [ "rbd", 252 ] # # This configuration option is advanced. # This configuration option does not have a default value defined. ...
7、标准帐户类型的用户允许关机，重启 解决问题：标准帐户类型的用户，默认无法关机、重启，是没有这些按钮的，按如下设置可以解决该问题。 Computer Configuration > Windows Settings > Security Settings > Local Policies > User Rights Assignment > Shutdown the system 添加Users组即可。 工作站默认的组（指windows 10）：Administrators, Backup Operators, Users. 服务器默认的组（指windows server 2019）: Administrators, Backup Operators.

开启备份
默认情况下，Windows Server不启动系统备份，也不会创建系统还原点。如果像我一样Windows绝缘体经常遇到“蓝屏”的话导致系统无法启动等问题还真是很让人崩溃。所以很有必要开启Windows备份，在先前已经安装了Windows Server备份功能，所以搜索 Windows Server 备份应用，即可配置备份设置。

When I install RHEL8.x I cound’t discover my RAID Controller’s devices on Install Storage set-up optional.When I try to google find the resolutions I know a large number of storage controller device’s drivers has been removed from RHEL8,which means the Dell R710/R610 installed H700 RAID controller card won’t be supported RHEL 8.X natively.
Nevertheless you can still install RHEL8 on these machines with use of driver update disk(DUD).
Setup DUD
Using this link below ,you are specifically looking for the megaraid_sas drivers.

If you specific DUD drivers that you need for RHEL8 is below address to download.
Download RHEL8.x media file and burn to usb or dev devices media.
Download DUD drivers in iso format and burn to usb drive.
Boot with both RHEL8 and DUD mounted before booting Install RHEL.
Installer should detect the DUD iso and install the proper drivers.
During booting RHEL8 Installer and When you see a countdown on the screen.At this time interrupt the installer with the TAB key and append the following to your boot options last.
inst.dd=/dev/sdb
On my system, the DUD was /dev/sdb and the RHEL8 install media was /dev/sda.
Soon after you can view the RAID Devices find it out.

超文本传输安全协议(HyperText Transfer Protocol Secure),缩写HTTPS，也常称为：HTTP over TLS、HTTP over SSL 或 HTTP Secure。是一种计算机网络进行安全通信的传输协议。HTTPS经由HTTP协议进行通信，但是利用SSL/TLS来加密之间传输的数据包。HTTPS开发的主要目的是提供对网络服务器的身份认证，保护交换数据的隐私与完整性。这个协议由**网景公司(Netscape)**在1994年首次提出。
