Hi guys. I try to configure drbd and I get this error
drbdadm create-md repdata
v08 Magic number not found
md_offset 319165534208
al_offset 319165501440
bm_offset 319155761152
Found ext3 filesystem which uses 311685096 kB
current configuration leaves usable 311675548 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.

I am new with this and I will appreciate a idiot proved howto or
explication :))
Thank you
