somewhere in the BIOS you could have option 'boot external RAID BIOS first' or similar. Or your RAID BIOS (if existing) might have option to force it to be the boot device. If you don't, as a workaround, you could install grub on SATA drive too: grub-install --recheck /dev/sdX (where /dev/sdX is your SATA drive). Then no matter which drive was first, grub ...

This message is telling you that if you turn the disk to dynamic, you'll only be able to boot that Windows installation. If you don't have other OS installed on your computer, don't worry about it. More: with a dynamic disk you'll be able to do software RAID 1, but no RAID 0 to a Windows installation volume. You can get RAID 0 with a hardware controller o ...

then why isn't it possible to say it: relax, everything already identical, As you will notice in the man page (man mdadm) --assume-clean Tell mdadm that the array pre-existed and is known to be clean. It can be useful when trying to recover from a major failure as you can be sure that no data will be affected unless you actually write to the ...

It is generally true that you need a separate /boot unless you want to boot the system on a single of the two RAID1 disks and then remount as md after the system is running or set up an appropriate initramfs. From mdadm wiki: Since support for MD is found in the kernel, there is an issue with using it before the kernel is running. Specifically it ...

RAID operates below the file system level. So it has no idea that the partitions are "empty". It is simply copying everything from one partition to the other. Assuming that the 3.9 tera-block number is the size of each partition, also the number of blocks in the final array, then you have two partitions of 2 TB each... this means it is copying 2 TB. 2 TB / ...

You won't be told unless there's a utility/facility to alert you, and it's configured. Additionally if the RAID controller is hardware based it may display a warning ELD on the adapter. If it integrates fully with your chassis, you may get a warning light on the chassis (usually only server-grade stuff does this). Otherwise you'll have to check its status ...

I can understand cache protection being required for stripping. But is it required for mirroring? Technically it is not required for either. It just increases performance and risk. If you want to be 100% sure then you: Do not use writing caching on the RAID card or use a BBU/flashbackups/ZMCP. Turn off write caching in the drives itself. But RAID ...
