I was flowing this guide.



I'm using Linux Mint but it's Ubuntu based so it shouldn't be too much of a difference. Anyways it all goes well until I needed to chroot and reboot, after I run apt-get to install mdadm inside the install, I get errors saying that it is unavailable but it works fine in the live environment and then if I reboot I get a grub error saying:




vfs unable to mount root fs on unknown-block(5 0)




Any idea of how I can fix this or make a bootable RAID 10?

  • Personally I'd reserve a /boot partition on every disk (consider what happens if your only disk containing /boot is the one that dies. I'd also make the /boot partition at least 100MB rather than your guide's 50MB.

  • Please include in your question the output from fdisk -l showing the partition layout for all four of your disks.

How many registers does an x86_64 CPU actually have?

Image
Clash Royale CLAN TAG #URR8PPP up vote 2 down vote favorite I am currently learning reverse engineering and am studying the flags register. I had in my mind that rflags was just another name for one of the 16 general purpose registers, for example rax or rbx . But it looks like rflags is actually an additional register. So that makes 17 registers in total... how many more could there be? I have spent at least an hour on this and found numerous different answers. The best answer so far is this, which says that there are 40 registers in total. 16 General Purpose Registers 2 Status Registers 6 Code Segment Registers 16 SSE Registers 8 FPU/MMX Registers But if I add that up, I get 48. Could anybody provide an official answer on how many registers an x86_64 CPU has (e.g. an Intel i7). Additionally, I have seen references to 'hardware' and 'architectural' registers. What are those registers and how many are there? register x86-64 share | improve this...
