I think I have somehow lost almost 4TB of data and I don't even know how. Let me give you a little information.
I am 100% completely new to unraid, linux, servers, all of this. I have always been a windows guy and have been running a Nas for quite some time, I'm very techy but have never dabbled into this field. Recently I got some extra computer hardware and decided to build a little server box that could replace my NAS and maybe do a little Server work for me as well (Plex, games, the like). I have spent the last few days slowly transferring files over this Unraid box. 1 drive at a time because I did not have enough drives to do 1 big transfer. I transfer a drive over, check to make sure everything is good, format the "Old" (Less then 1 year old ironwolf drives) then install into the unraid server and start transferring another drives worth of files over. I finally got all of this completed this morning and then I went ahead and installed a 1tb M.2 SSD and another 4TB Ironwolf drive and set them up as my cache drive and parity drive and then I let the box sit there for the majority of today and work on building the parity drive. I get back home tonight and check on it and the parity drive is complete, I take a look at my array and I notice that it now says 5TB used not the 8TBs it was showing this morning. I look through my shares and sure enough an entire drives worth of data is missing.......... The other thing I noticed is that I lost my Krusader file explorer docker as well ( which is what I was having do the file transfers through a smb share). Looking at the shares and folders I believe I lost the entire first drive I had installed in there worth of data. This was a brand new drive that I just bought..............
What do I do now?
I honestly don't even know what has happened, I have been so careful about moving things over in a very organized manner double and triple checking everything. I was so happy everything moved over correctly and relieved that I could get the parity drive built finally and now it seems I have lost so much stuff that will take me months to get back if I ever even do manage to get it all back.
Is there someway for me to check and see what happened? Logs somewhere? A recycling bin of file histories or some other way of looking at these now seemingly empty drives and seeing if there was something on them? Like I said other than installing a cache drive and a parity drive and allowing parity to build today I have done nothing else, no files transfers or anything else yet...
I'm sooo bummed I honestly just feel like trashing this whole server and going back to my crap nas all of my excitement about this whole project and all of its potential is gone.
Any help would be greatly appreciated. I'll be here being depressed if you need me.
