online shrink not supported in EXT4_IOC_RESIZE_FS ioctl


Hi,

I was referring EXT4_IOC_RESIZE_FS ioctl implementation in linux kernel ver 3.3.8.

It is given in the code that online shrinking not supported.

if (n_blocks_count < o_blocks_count) {
/* On-line shrinking not supported */
ext4_warning(sb, "can't shrink FS - resize aborted");
return -EINVAL;
}

Can anyone please tell the reason why online shrinking is not supported.

Thanks in adavance.

Regards,
Raphel
