Yes, it appears that you replaced the right drive. Sorry for this, but having to walz around pages of the thread looking at screenshots does not help.
If the data is lost its lost, like I said in the thread this is my backup I use in DFS so I still have all my data. Might be easier just to replace the other disk too and start over.. ugh
Well, if you have all your data you should just destroy the pool, replace the dead drive and then recreate the pool (consider going raidz2).
Also make sure to set proper smart test scheduling (as well as scrub) and check those results with regularity,
especially if you use raidz1!
Also, for all that's computing please use something that makes you able to copy paste the outputs of the commands (like putty). That's a plea I do on behalf of the community to everyone who ask for help.
