The message comes from SCSI: https://elixir.bootlin.com/linux/latest/source/drivers/scsi/sd.c#L2508 Reading drive capacity could be totally opaque for the filesystem, eg. when the scsi layer compares the requested block address with the device size. The sizes of blockdevices is obtained from the i_size member of the inode representing the block device, so there's no direct read by btrfs. You'd have better luck reporting that to scsi or block layer mailinglists. -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
