[DRBD-user] metadata upgrade from 0.7.22 to 8.2.5

[Jure Pečar]

Hello,

I'm following Florian’s blog to upgrade drbd from 0.7.22 to 8.2.5. Now that I've managed to compile latest drbd, I'm stuck at the last step before starting it up, upgrading the metadata.

As I understand, drbdadm should detect the presence of v07 metadata and offer an upgrade. But instead I get this:

# drbdadm create-md drbd0
v08 Magic number not found
md_offset 578730696704
al_offset 578730663936
bm_offset 578713001984

Found ext3 filesystem which uses 565035628 kB
current configuration leaves usable 565149416 kB

 ==> This might destroy existing data! <==

Do you want to proceed?
[need to type 'yes' to confirm] no

Operation cancelled.

Google suggests these info might be useful to you to figure out the problem.

Any hints?
