Does it only happen at a 2TiB threshold? In my case, it seems to me that there's two bugs that I encountered: 1. the free space cache being invalid blocked any and all resizes. This was fixed with fsck (maybe resizing the fs to smaller and then to max size contributed to the fix as well) 2. when i copy files onto the fs, most of the time the resizes work correctly, but every now and then they won't, and it seems to me like this only happens when there's a lot of data being copied, the cpu is hot, likely the usb controller is hot, etc. It seems to me like at that point the hardware just becomes less robust (without exactly becoming buggy). -- 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
