That's an interesting one. Line 2511 in enbd-client.c is


        if (size64 > 0) {
            err = setdevicesize (self, size64);
            if (err < 0) {
                PERR ("Failed set size %Lu on fd %d: %m\n",
                                (unsigned long long)size64, dev);
                return -EINVAL;
            }
            DEBUG ("client (%d) set size %Lu\n", self->i,
                            (unsigned long long)size64);
        }

so it looks like the setdevicesize routine failed with some error number
that I don't know offhand ... EFBIG. 27. Can you switch on the DEBUG
messages in that routine (same file) by replacing them with MSG
calls?

I would assume the problem is in the kernel driver however.  Can you
remind me of the precise patch and I'll compare it with the 2.4.33pre
code?
