And why the avail is negative number?? Raw device size is: 745 GB. UFS reserves 8% of disk space so that only root can fill it (for performance reasons but also for security - so that ordinary users don't fill the drive). The size of this reserved space is: 745*0.08=59.6 GB, and when you fill it, this intentionally gets reported as negative value. The differences in the output (109% instead of 108% and 58 GB instead of 59 GB) are most likely due to rounding errors. The real question is why does df report 722 GB free, when it should be reporting 685 GB (745-59.6=685.4).
