What's my raid configuration?

[hytga]

Hi folks. New to Freenas and very rusty on linux. So i was hoping to get a few answers about my raid configuration on the freenas.

I have two 1TB HDDs on the freenas box, WD Red 1 TB Internal HD ‑ SATA ‑ 4" ‑ WD10EFRX

Since i have barely 1TB available on the box, i'm assuming freenas configured it as a mirror or whatever the equivalent of Raid 1 is. If i understand it correctly... when either of the drives fail, i can just change the failed drive without loosing data?

Here're some commands i was able to put together from reading the forums. A confirmation of my "assumptions" would be appreciated.

Code:

[root@freenas ~]# camcontrol devlist                                         
<WDC WD10EFRX-68FYTN0 82.00A82>    at scbus0 target 0 lun 0 (pass0,ada0)     
<WDC WD10EFRX-68FYTN0 82.00A82>    at scbus1 target 0 lun 0 (pass1,ada1)     
<ADATA USB Flash Drive 0.00>       at scbus3 target 0 lun 0 (pass2,da0)

Also. I have weekly snapshots, but i'm unsure if those are actually taking place.

I have snapshots that have Used: 0, Refer: 96kb


But i'm pretty sure that ALOT more data is bing changed weekly than just 96kb. Is there something wrong with my snapshot setup?

Yes, and yes ;)

If you have to replace a drive in the future - please follow the directions in the documentation.

We often have users who think they can just yank a drive and replace it. Please RTFM first.

lol of course.... may be new to freenas, but not that dumb :D

but thanks for the manual pdf link. Would def come in handy.

It's also quite helpful if you place the output of the commands you ran in code tags to make easier to read.

If there's a week where nothing changed, that would be reasonable. Do other snapshots show space used?
