If a volume is online, then there are certain things you can't do. Did you try to shrink it with some bootable version of GPARTED?
Sorry but I fear this is one of those old issue/discussion things. I might be short on the explanation.

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
