Hello, I met a problem when resize btrfs as follows. The btrfs related sysinfo is attached at the end of this mail[1].
$ dd if=/dev/zero of=btrfs_5gb.img bs=1024 count=5000000 $ mkfs.btrfs btrfs_5gb.img $ sudo mkdir -p /mnt/btrfs_5gb $ mount -t btrfs btrfs_5gb.img /mnt/btrfs_5gb $ btrfs filesystem resize +10g /mnt/btrfs_5gb Resize '/mnt/btrfs_5gb' of '+10g' ERROR: unable to resize '/mnt/btrfs_5gb' - File too large Is it a misuse case of resize? And I expected not the message "File too large" but different error message. Thanks.
