Centos 6 software raid boot

I will be listing few important ones. Linear mode — Two or more disks are combined into one physical device. But if several users use the device, several users using different disks at same time, you will see a performance gain. No data rescue is possible if a drive fails. RAID 1 — This level has redundancy. If there are spare disks available, and if the system survived the crash, reconstruction of the mirror will immediately begin on one of the spare disks, after detection of the drive fault.

I've never had to do anything like that before? Rebuilt the initramfs file and kernel panic's on startup not being able to find LVM. I'm guessing I need to add lvm into the ramfs somewhere???

But every incantation I've tried gives me an error. What would be the magic command to add lvm and md to initramfs? Post by technoworth » Tue Nov 29, pm For all you folks, I have found a workaround that works for me..

May be this may help you guys.. Here it is: Raid mount disappears because the system is not reading the mdadm.

So far I've found the following ways: 1. I can live with having to do something, whenever there is a kernel update, but of course I'd rather be free How do you normally handle software RAID and booting? Re: Recommended way to setup boot robust RAID1 in CentOS7 Post by TrevorH » Wed Jul 30, am I believe that option 1 in your list is the preferred method but whatever way you choose still has the drawback that the computer's BIOS doesn't know about software RAID so when it boots, it will always attempt to boot from the boot records on the first physical disk or whichever one it has been configured to choose.

If you have just replaced the first disk because of failure then it will be blank and the boot will fail. Use the FAQ Luke. The more "out of the box" you make your OS, the simpler it is to maintain down the road with far few problems then when you wedge it onto something that requires a special setup just to boot. For the 2. The server is for private use only, which unfortunately also limits the budget Otherwise I see that the obvious choice is a real hardware RAID controller.
