Hello, I wanted to resize my filesystem to 512MiB less. I had created the btrfs after I had set the partitions some days ago, and it was like this: # cat /sys/class/block/sda1/size 234436482 Getting in bytes: 234436482*512 = 120031478784 I run: # btrfs fi resize -512m / And I see in dmesg: btrfs: new size for /dev/sda1 is 119494606848 But that's not the previous size - 512MiB. It is: 120031478784 - 119494606848 = 536871936 = 512*1024*1024 + 1024 So, there is an 'off by +1024'. I shrinked the partition to +1024 bytes bigger than would be by subtracting 512MiB, just in case. What is that off by 1024? This is 3.5.4.
