Hi, dear friends,

 

I had configured drbd-8.3.0 well.

In order to make the disk clean, I issued command "mkfs   /dev/sda10";

then issued command "drbdadm create-md  r0", then meet below problem:
 

++++++++++++++++++++++++++++++++++++

linux-10:~ # drbdadm create-md  r0
md_offset 50009665536
al_offset 50009632768
bm_offset 50008104960

Found ext2 filesystem which uses 48837568 kB
current configuration leaves usable 48836040 kB

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 /dev/drbd0 v08 /dev/sda10 internal create-md' terminated with exit code 40
drbdadm create-md r0: exited with code 40

+++++++++++++++++++++++++++++++++++++++++++++++

 

Would you help to explain this?  No important data on the disk, 

I just want DRBD works,  what can I do ?

 

Best regards,

Edward
