Are you sure that IP Virtual Server is built in the kernel or as module?

在docker 镜像中跑lvs时会有这个提示,找遍了百度都没找到答案,直到我想运行systemctl时提示我 :Failed to get D-Bus connection: Operation not permitted

原因是docker run 的时候后面没有跟 /usr/sbin/init 服务,然后惊讶的发现我lvs也能起来了。。。。。。

### Dell R530 Server with PERC H810 or H830 Controller Setup RAID 1 Configuration Guide #### Preparation Before Setting Up RAID 1 Before configuring RAID 1 on a Dell R530 server using the PERC H810 or H830 controller, ensure that all necessary hardware components are properly installed and connected. Verify BIOS settings to allow booting from the intended storage device. #### Entering RAID Configuration Utility To enter the RAID configuration utility during system startup, press `Ctrl+R` when prompted after restarting the server[^1]. This action will bring up the RAID configuration interface where various operations can be performed including creating new RAID arrays like RAID 1. #### Creating RAID 1 Array Once inside the RAID configuration menu: - Select two physical disks of equal size. - Choose "Create Virtual Disk". - Specify RAID level as RAID 1 (mirroring). - Confirm selections; this process may vary slightly depending upon specific versions but generally follows these steps closely[^5]. After setting up RAID 1 successfully, initialization might start automatically or require manual initiation by selecting an option similar to “Initialization” followed by confirming it through actions such as pressing F2 key then choosing star init command which starts initializing newly created RAID volume. #### Verifying Installation Upon completion of RAID creation and initialization processes, verify installation correctness via checking within operating systems’ disk management tools ensuring mirrored volumes appear correctly without errors present. For Linux distributions specifically, make sure kernel includes support for relevant RAID controllers found under directory path linux-\drivers\scsi\megaraid containing driver source codes along with Kconfig files listing supported models[^3]. ```bash lsmod | grep megaraid_sas ``` This command checks whether the required module is loaded into memory indicating proper recognition at OS-level. #### Best Practices Post-Configuration Maintain regular backups even though data redundancy exists due to mirroring nature provided by RAID 1 setup. Monitor health status periodically utilizing built-in utilities offered either directly from manufacturer software suites or third-party monitoring applications designed explicitly towards managing enterprise-grade storages efficiently over extended periods reliably safeguarding critical business information assets effectively against potential failures while maintaining optimal performance levels throughout operational lifecycles continuously. --related questions-- 1. How does one check if the correct drivers for PERC H810/H830 are included in custom-built kernels? 2. What precautions should be taken before performing any changes related to RAID configurations on production servers? 3. Can you provide detailed instructions on how to monitor RAID array statuses post-setup? 4. Is there any difference between setting up RAID 1 on older versus newer generations of Dell PowerEdge series servers? 5. In what scenarios would switching existing non-redundant setups to RAID 1 offer significant advantages?
