First time user for Centos 7. I have set up a server running a Centos 7 minimal install and set it up to use RAID 1 with the following guide:

According to cat /proc/mdstat my raid 1 is up and running.
If I wanted to do a simple test of something like make and save a .txt document, how would I tell if it was mirrored to sdb from sda?

Simulate a failure on each disk in turn and check if the file is there.

Re: Centos 7 minimal install RAID 1 questions.
Some sidenotes :
When using software raid - you can use raid10 mode with far layout and 2 disks to increase the reading speed -ofcourse the storage will be 50% of a raid1, and the write speed will drop a little.
Regarding your question - the best way is to disconnect a drive (or just simulate it via server's bios) and then check.
