DRBD構築中、メタデータの作成で「Operation refused」エラーになった件

# drbdadm create-md drbd0
md_offset 2199023251456
al_offset 2199023218688
bm_offset 2198956109824

Found LVM2 physical volume signature
  2147479552 kB data area apparently used
  2147418076 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.
