I have been experimenting with converting a data disk from ReiserFS to BTRFS with a 1TB drive. I am finding that after formatting the 1TB drive for BTRFS, it is only showing 459GB as available. Is there something unique about BTRFS that I am not understanding? More relevantly, is it inadvisable to use BTRFS as a data disk?
Below is the BTRFS file system info:
Data, single: total=459.01GiB, used=458.43GiB
System, single: total=4.00MiB, used=64.00KiB
Metadata, single: total=1.01GiB, used=516.22MiB
GlobalReserve, single: total=512.00MiB, used=0.00B
