10. Dynamic Planning (3) -- 0-1 backpack problem, 0-1 backpack
In the previous article "9. Dynamic Planning (2) -- Subsets and problems", we talked about Subsets and problems and their implementations. Backpack problems are actually a subset and a type of problem, but the pr

To recover, the offending are removed, and only the mirror of the "The stripe needs to be Resync ' d."The difference between RAID 10 and RAID 0+1RAID 10 and raid0+1 are two completely different implemen
Learning node (2) from 0 to 1 and building an http server
During the course of the previous section, we learned about the connection and differences between different module specifications. In this section, we officially started learning about node. First, we started from setting up an http server and running simple p
and format it into the same file system as RAID 1. ThenWe will simulate a partition failure and use the command
Mdadm -- fail/dev/md1/dev/sda7. The sda7 in md1 is crashed.
Now we need to use the partition just now,Install a good disk and then a bad disk to avoid secondary harm.
Mdadm -- add/dev/md1/dev/sda9 [after installation, it will automatically synchronize with another disk]
Remove a bad Disk:
mdadm --remove /dev/md1 /dev/sda7
Because RAID
Graphic RAID 0, RAID 1, RAID 5, RAID 10
RAID (Redundant Array of Independent Disk Independent Redundant Disk Array) technology was proposed by the University of California at Berkeley in 1987, initially to combine small cheap disks to replace large expensive disks, at the same time, we hope that when the disk fails, data access will not be damaged and a certain l

this time, the third and fourth disks are idle. When B data is written to the third Disk in a certain band, and B data is checked in the fourth disk, in this way, both data a and data B can be read and written at the same time.
VII. Raid 6
Raid 6 adds a verification area on the basis of RAID 5, each of which has two verification areas. They use an unused verification algorithm to improve data reliability.
Next we will introduce several types of combined raid
2-0. Integer four Arithmetic (10), 2-0 integer four arithmetic 10
This topic requires programming to calculate the sum, difference, product, and Quotient of two positive integers and output them. Ensure that all input and output are in the Integer Range.
Input Format:
Input two integers A and B in A row.
Output Format:
bit crazy because it was a simple method and the fault tolerance was good (of course, the fault tolerance here is also a kind of error !)
I firmly believe that there must be other methods, but I haven't thought of them yet!

I had an interview that day. I encountered such a problem: input 0, output 1
