How screwed am i?

[TitanNas]

Two days ago i got an email stating that there was an error on one of my spinning drives.  Then i noticed the whole server went down.  It does not seem to be booting and i cannot reach it on the network. 

 

The osd is attached below but i can't really make sense of what it is telling me.  Thank you in advance for any help you can provide.

i would start troubleshooting my unplugging all drives other than your boot drive and see if you can boot into HexOS/TrueNAS

Can get it to boot now as long as one drive that i think was the one that had 1 zfs error but it was online. One drive unfortunately isn't be recognized as being connected. The last two of the four are showing connected. Unfortunately the pool is still offline since i am missing two drives. 

 

I still need to trouble shoot with new cords and power yet. 

 

I'm going to order four new drives as well hoping i can still save it. 

 

What's anyone's recommendations to best recover this pool. 

 

 

 

I also really need to finish my off site back up. I hope i don't loose anything terrible feeling.

The two drives that were part of the 4 drive array are showing as unused drivers.

Very good chance the one drive that is preventing you from booting has gone bad.
I would also try to double check if all the cables are connected to the 2nd drive that is not showing up in hopes that it has not gone bad as well.
