I ran across this helpful guide for replacing a drive in a RAID setup. An important thing I saw in it was the one step clone partition set-up, which can be really handy if it does what I think it does. Will definitely try it next time I’m adding a hard drive to an array.

This is just a postlet for a) remembering how to do it and b) your information

If something changes about your network, and you run into an offending host key problem because you have enabled strict checking in your SSH’ing, you can use the following sed command to remove that key. Just replace the ‘6’ with the line number given to you and away you go!

# sed -i '6d' ~/.ssh/known_hosts

Happy Hacking!
