I have btrfs /home partitions on two machines, a laptop with Fedora 11.91 (Rawhide) x86_64, and a netbook with the same OS, i686 (32-bit). Both with kernel 2.6.31-2.fc12 and btrfs-progs 0.19. /home directories are both converted from ext4. On the netbook, everything is fine; on the laptop, I thought everything was fine until I ran a program installer that checks the amount of disk space. To my surprise, I then noticed that it is as follows: $ df -h /home /dev/mapper/system-home 212G -64Z -99G 100% /home Doing btrfsck on the partition does not produce anything out of ordinary: # btrfsck /dev/mapper/system-home found 163919360000 bytes used err is 0 total csum bytes: 158147320 total tree bytes: 1976504320 total fs tree bytes: 1623146496 btree space waste bytes: 540904631 file data blocks allocated: 215433904128 referenced 161871007744 Btrfs Btrfs v0.19 The same laptop has been used to format an external hard drive as Btrfs, and the reported disk space on that drive is fine as well. Deleting ext2_saved/image does not change the result reported by df. Any more data I could provide? I'd rather not image the drive as it is huge (and contains some personal data). I could, of course, backup, create a fresh filesystem, and restore, but would prefer to not do that if this problem needs troubleshooting.
