Dear All,
My machines have suffered the same kind of problem as posted at earlier day:
http://lists.linbit.com/pipermail/drbd-user/2004-September/001853.html

The suggestion theres were:

>is it possible that you set up drbd with internal meta data on top of an
>existing filesystem, and you happen to have overlooked the line in the
>documentation where it says DO SHRINK THE FS FIRST ?

>if not, do you happen to use drbd with internal meta data, but you
>mkfs'ed on the lower level device? Don't do that, then.

I don't sure my understanding. So I asked once more before I make mistake.

Q1) Does it mean that, we should not format the filesystem (or format
the disk) indivdually and then config them under the drbd?
Q2) Does the correct procedure is, we let the filesystem not
formatted, start drbd and we format the drbd block device (for example
drbd0)?
Q3) If I have already formated them individual and get the errorr
message "Input/output error", can I fix the problem by formatting the
block device now?

Thanks in prior.

Seki K.S. Lau
