Exchange mounted directories between 2 file systems

I have these two directories mounted on their respective file systems:



/dev/sda5 300G 18G 283G 6% /opt
/dev/sda6 58G 76M 58G 1% /srv


The situation is: /srv needs more disk space than /opt. Thus, I want to mount /srv on sda5 and mount /opt on sda6. Just an exchange between file systems.



Is it possible? How can I do this?






filesystems mount suse

  • Yes but they would need to be unmounted. You would need to boot off a live media, copy the data over to "independent" media using dd, and then copy them back in reverse. Finally the mount points would need to be changed in /etc/fstab

  • Understood. But I think this will not be possible. I think that a better approach is to resize sda5 and sda6. Thanks for your answer.

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...
