  1. Are there any DrivePool devs that can weigh in on this?
  2. @Chris Downs, No, that wouldn't seem to work either. That strategy would still rely on the balancer to do it's job AFTER the data has been transferred to the pool. Again, according to the comment I quoted above, DrivePool will always place new files on the disk with the most free space and then rebalance the data between the drives according to the selected balancers. So, basically forget about balancers as they act AFTER the data has already been written to the pool. What I am desiring is an option to initially place new files on the drive with the least % used at the time the file is written.
  3. @Chris Downs, Disk Space Equalizer is the only balancer I'm using and it is above all others in the list. Based on the comment quoted above, my understanding is that new files will still be placed on the drive with the most free space and Disk Space Equalizer would still then move the files to another drive after that. So, while the end result may be the similar, it's not the same as having the new file initially placed on the drive with the least % used. Having this balancing done after the fact results in an extra data transfer, once to the pool(to the drive with most free space) and then to the drive with the least % used. This extra step can take considerable time when double digit terabytes are involved. So, my inquiry was really more about being able to have new files initially placed on the drive with the least % used, provided the disk has sufficient space of course, and not having the need for balancing after the fact. To be honest, I have not enabled the option to balance immediately as I was under the impression this wouldn't help as it would still have to balance after new data is written to the pool.
  4. @Christopher (Drashna), I just started evaluating DrivePool and see there is still not an option for real-time balancing for file transfers based on percent used. I would like this option to help optimize disk read performance since it would help equalize files being written to the outer space of the hard drive platters. I understand the potential issue you noted in your previous post. But, is it possible to get around this scenario by identifying the size of the file being transferred and store it on a disk with sufficient space if the drive with the lowest percent used doesn't have capacity?
