[DRBD-user] DRBD online resize drbd dual-primary on Pacemaker

[Igor Cicimov]

Hi,

According to https://docs.linbit.com/docs/users-guide-8.4/#s-resizing,
when resizing DRBD 8.4 device online one side of the mirror needs to
be Secondary. I have dual primary setup with Pacemaker and GFS2 as
file system and wonder if I need to demote one side to Secondary
before I run:

drbdadm -- --assume-clean resize <resource>

or it will still work while both sides are Primary? The resource has
internal metadata.

Thanks
