I did not want to blame Drivepool, I've been using it for years and have been a supporter the entire time, but something's going wrong with my servers and I think it's due to the latest beta. I upgraded a while back based on a recommendation, but now I can't keep my servers up. Don't worry, I'm not upset, I can recover from whatever happens, but this is just getting tiring trying to figure out what's going on.
It all started when one of my WD 5TB Red drives starting throwing SMART errors on "server 1", reported by Scanner. Not long after that, I started getting corruption errors. To make matters worse, the STxxx blah blah 3TB drive I use as a dup drive on a second VM also started failing, and throwing errors. Two problems at once. Joy. So, I pulled both drives from "server 2" and replaced them with 4TB HGST NAS drives. OK, so that one has been stable since. But, I'm still fighting issues on "server 1". I bought a 8TB archive drive, since I was running low on space anyway. It took me SEVERAL days to get all the data to the point I could remove the 'failing' WD 5TB drive. But, finally, after hours and hours of chkdsk /f and chkdsk /r and trying to move data, rinse repeat, I finally got that drive to remove. OK, things look good. I go a couple of days and it seems things are stabilized. Oh, I spoke too soon. Data is corrupting not only on the other 5TB drive, but now also data is corrupting like crazy on the new 8TB drive. I can't do a dang thing, I can't breathe in the general direction of the box even, without having data corruption and everything screwed up.
I don't know what logs you need, what ANYTHING you need. You know I've supported Drivepool and Scanner. Maybe I'm wrong and it's not the fault. But I can't think of what else it might be. I haven't jacked around with anything that I know of.
