The farm took a hit

I went to replace what I thought was the loud TR-004 with a new one. After swapping drives around and powering it up the TR-004 decided it had one drive of 54TB and btrfs couldn't mount it as the other drives were missing. This is despite the dip switches on the back being set to JBOD mode. Pressing the Set button on the back didn't help. Changing the dip switches to individual mode didn't help. Swapping everything back into the original TR-004 didn't help either. I ended up wiping the array and reinstalling everything.

I have been filling it up, currently we're up to 320 plots. Using 16TB drives they hold 560 plots with a bit of free space left over. I have it doing a defrag which has been going for 3 days now. It needs enough free space to do the defrag. Its online while doing the defrag meaning the harvester can still access the plots.

You'll notice I said above what I thought was the loud TR-004. It turns out it wasn't the loud one. For a bit of context I have 3 of them in a row sitting on a wire shelving rack, there is barely 10MM between each one. I worked out which one it was and swapped it out. Same problem as above. I need to repopulate it as well so I am down two TR-004's at the moment, although one is mostly filled. 

The solution seems to be press and hold the Set button on the back, it will beep after 3 seconds but continue to hold the the button for another 3 seconds. The manual only mentions press and hold the set button for 3 seconds to set the mode. Why you have to set the mode I am not sure after all the dip switches should be enough for it to know what mode you want.

May 2024 update

As mentioned in my previous post I replaced all the drives in my primary storage server with larger ones. I am still trying to fill it up. Unfortunately the Bladebit plotter seems to lock up regularly and when I notice I have to shut down Chia, delete the temporary files off the SSD and the half-done plot that it was working on when it locked up. Top shows a zombie task and the plotter seems to have lost track of it. The 2nd WD 16TB drive that I returned under warranty has been rejected. They claimed it has a dent on the back of the drive, so likely shipping damage when I got it. I had 12 of these drives, now 11, so no point wasting any more money on the WD drives. I currently have two Qnap TR-004 units that hold 4 drives each, so 8 drives are enough. I need to fill the primary storage server before working on the TR-004's.

March 2025 update

I currently have 2597 plots spread between 4 harvesters. Due to heat I have had the Chia farm off for multiple days which doesn't help with winning blocks or for filling up the 2nd TR-004. Current storage consists of: Main storage is a 10 x 20TB machine running ZFS file system, raidz2 (1460 plots) Secondary storage is 7 x 8TB machine running ZFS file system, raidz1 (397 plots) Pi5 (8GB) + TR004 with 4 x 16TB drives running bftrs file system, raid0 (560 plots) Pi5 (8GB) + TR004 with 4 x 16TB drives running btrfs file system, raid0 (slowly filling - 190 plots) I have a I5-11000 machine as the full node.   The good news is the  Pi5 + TR004 seems quite scalable, that is its fairly easy to add another one and once filled can switch it over to being a harvester. I'm seeing average latency on the Pi5 harvester of 400ms and max of 1.5 seconds, so it seems able to handle the random reads. While one could use a rack mount system with tons of drives I don't think the returns are enoug...

April 2024 update

I bought 10 x 22TB Seagate HDD. Last week I bit the bullet and removed all the 16TB HDD from the primary storage server and put the 22TB drives in. I am now plotting away trying to fill it up. The Bladebit CPU plotter seems to lock up my full-node so I have to check on it once a day. The used 16TB drives are destined to go into a couple of QNAP TR004 units running in JBOD mode plugged into a Raspberry Pi5 running as a harvester. The TR004 can hold 4 drives. If this setup works out I will look at replacing the two Pi4 + external HDD's with Pi5 + TR004 units. I might have 3 of these as it seems a fairly inexpensive way of adding another harvester with 64TB of disk space. Speaking of the 16TB drives, I returned a 2nd WD 16TB HDD and picked up a replacement under warranty for the previous drive that I returned. It had been sitting at the computer shop for almost 3 months before I drove there to pickup the replacement. Thats 2 out of 14 WD drives that have failed so far. The lack of rel...
