DRBD9 crash after update to PVE 4.1

[tatyrza]

Hello.
After update from 4.0 to 4.1 my shared DRBD9 storage was dissapeared from GUI. On one host resources was in secondary role, and on second host there are no resources at all. I've put resources DRBD on line on first host by the drbdmanage console tool. Now I have single host DRBD storage. The question is: how to clean drbd configuration on second host, and rejoin it to drbd cluster without loss data?

Note also what http://drbd.linbit.com/home/roadmap/ says:

Drbd-9.0 is already available as prerelease, but not yet stable.

Thanks for reply. Pity that there is no information about instability in the proxmox documentation wiki. Greetings!

The introduction clearly states that DRBD9 is technology preview, seem you missed this.
