Hello everyone. This is my first post and I hope to get to know everyone a little better. I do hope that my forum behavior is acceptable as I don't often post in forums. :)
I have been a long time user of FreeNAS, since about 2013. I have loved using it and for the most part it has always, well, worked. Never had any problem with it that was not my own doing (Usually configs). But being a lurker, I have been able to solve most if not all of my issues with the plethera of information that is posted on these forums. That is until this morning...
Let me lay out the story and I will post all the information that I have. Let me know if I need to gather more information and I will be happy to get it.
So I logged onto my workstation and found that my SMB shares was missing folders, not disconnected, just missing a ton of folders. Thats odd, so I log into the GUI to find that the directory is basically empty other than a few files my wife uploaded earlier. So I have seen issues in the past that are easily resolved with a simple reboot. OK, power cycle the system and it comes up with a error while booting. "error 32 LBA something...". Okay, so I get a bootable usb drive, just to check if it the port, the usb drive or something on the usb drive. Well it boots. So i do some searching and it appears that I may have a toast USB drive. Fine, I have a backup config from earlier in the week. Easee-peezee. Except that someone wiped my backup configs. Darn! So here is where I fall back on why I love FreeNAS and zfs so much because I can just import the pool again and sure I'll have to fix all my configs, but the data will be there.
So I install a fresh copy of 11.2-RELEASE-U1 from the website. No biggie and things are going along quickly. Now its time to import the pools. I import pool "Dump" which is exactly that and it appears it has some bad sectors, no biggie, it was a, well, dumping ground and I dont take backups for that pool. But when I import the pool, all the datasets are missing. Thinking this might have something to do with the bad sectors, I move onto my second pool "MainStorage". I have never in the 3-4 migrations that I have done with this pool ever had a problem with it. I do the same thing and import the pool and same issue. Datasets are missing. About 4.2TB worth of it missing.
Now I dont think the datasets are missing, i just dont know how to get them to show up exactly. I have scoured the forums to see if there is anything and everyone that I have seen either has SOMETHING no their pool or nothing at all. And this with nothing at all appear to end up restoring or never respond to the thread again.
So, that leads me here. I will post all the information that I have gather based on information requests from others in past threads.
The pool that I care the most about is the MainStorage pool so you will only see Dump show up in list that are part of the global lists. What I am basically hoping for is to not do a full recovery on this pool. I can if needed, but I'd rather not if this is something rather simple.
Thanks Again!
