It seems like that drdb config fails. And I run "drbdadm create-md drbd-pgsql -W--peer-max-bio-size=128k", I get the following result:

Move internal meta data from last-known position?

[need to type 'yes' to confirm] yes

md_offset 21474832384
al_offset 0
bm_offset 0

Found ext3 filesystem
    20971520 kB data area apparently used
           0 kB left usable by current configuration

Device size would be truncated, which
would corrupt data and result in
'access beyond end of device' errors.
You need to either
   * use external meta data (recommended)
   * shrink that filesystem first
   * zero out the device (destroy the filesystem)
Operation refused.

Command 'drbdmeta 0 v08 /dev/cgts-vg/pgsql-lv internal create-md --peer-max-bio-size=128k' terminated with exit code 40

I'd like to know that how to config drdb or did I set some config wrong?
