Hi, Can someone explain me why there is a difference in the number of blocks reported by df and du commands below? ===================== # df -h /dc Filesystem Size Used Avail Use% Mounted on /dev/drbd1 746G 519G 225G 70% /dc # btrfs filesystem df -h /dc/ Data, single: total=518.01GiB, used=516.58GiB System, DUP: total=8.00MiB, used=80.00KiB Metadata, DUP: total=2.00GiB, used=1019.72MiB GlobalReserve, single: total=352.00MiB, used=0.00B # du -sh /dc 467G /dc ===================== df shows 519G is used. While recursive check using du shows only 467G. The filesystem doesn't contain any snapshots/extra subvolumes. Neither does it contain any mounted filesystem under /dc. I also considered that it could be a void left behind by one of the open FDs held by a process. So I rebooted the system. Still no changes. The situation is even worse on a few other systems with similar configuration. -- -Shyam -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
