  1. Update from this morning: I checked the status of my balance this morning after waking up, and can see that my drives are back to syncing at 10-20MB/s. I dug through and found the files that were even being transferred at that moment (they were shown as .copytemp files), and they were 50GB+ movies, which should definitely be maxing out that 200MB/s transfer speed these drives can do when working with files like that. So, back to square one. 😞
  2. Hi all, thanks for the input and advice so far. @VapechiK, I took your advice and reset drivepool settings and configured my balance settings to more or less the same as before. Basically, I turn off everything but disk space equalizer (by % used) and prevent drive overfill, and leave the automatic balancing settings alone. I've since started rebalancing again, and it's been plodding along at 50-80MB/s for the last 20 mins. It would start at those speeds before dropping to 10-20MB/s in the past, so fingers crossed speeds stay high. Regarding the drives reporting weird storage numbers, that's likely due to files that have been allotted disk space but aren't using that space yet, such as torrents and other files mid-download. Below is a pic of one such file. When considering all those files on a particular disk (often a lot, I tend to queue downloads all at once and drivepools puts them all on the same disk), it totals to more than the actual available disk space. Now that I'm expanding my pool it's not a huge deal, was only really a problem when all my drives were getting close to 95%+ full. @Shane, I did additional tests on S3D1 and S2D1 including a closer look at what has been moved to the .poolpart folders by drivepool. When transferring many small files, performance was expectedly slow, 5-20MB/s depending on file size, while large files were around 200MB/s. When I took a look at what had been balanced to those drives however, it was all large media files (not a surprise as that's 95% of my pool) so I don't believe that's what's responsible for slow balancing performance. As noted above my performance is a bit better since resetting settings but I will revisit this with an update after a couple of days. --- On a side note, this balancing behaviour seems a bit sub-optimal to me, and I'm curious if y'all have any input. At present, basically all of my drives need to balance in some way, either by filling up or emptying. However, only one of the empty drives has any balacing activity, and it's only pulling data from one other drive in the pool. It would definitely balance faster if it were filling both of the empty drives at the same time from multiple drives that are full. Is this a logic or file system limitation? TIA!
  3. Hi all, I've been using drivepool in conjunction with snapraid for a few years without issue, but have ran into a weird issue when adding two empty drives to my pool. For context, my current setup is an ITX PC (4x8TB drives) + Mediasonic probox (8+10+10tb) + mediasonic probox (3x14tb). Proboxes are connected via USB 3.0 and have had no issues maxing out their bandwidth when syncing with snapraid or balancing in the past. I consistently check SMART data and have confirmed many times that all these drives are able to hit their rated speeds via file transfers, both in and out of the pool. S2D2 is SMR, but it hasn't come into play during this issue yet and it's speeds aren't that far behind the other drives anyways. All other drives are CMR. I added 2x14TB drives to the pool, one in each of the proboxes. After re-measuring the pool, it calculated new balance targets and started balancing. It was taking an incredibly long time, only 5% after 24 hours, so I checked drive performance in Task Manager and one of the new drives (S2D1) was only doing 10-15MB/s while the other wasn't filling at all. I also found it odd that it was only balancing files from a single drive instead of multiple, but that could just be normal behaviour that I'm not familiar with. Note: I've disabled any scheduled snapraid tasks in the meantime to not interfere with the balancing. Things that I've tried: increasing priority of the balancing job. No effect on transfer speed. Tried stopping the balance and restarting with that enabled; no change. Looking for errant processes that are using disk resources - None I could find. Trying different balancing settings/plugins - same issue between all. killing drivepool service and restarting it. It started filling the other new drive (S3D1) but still at 10MB/s. Screenshots below showing the drive's performance in task manager and of the pool. Any ideas or suggestions are welcome! TIA!
