Good day,



I have an issue with drbdmanage Pool Free report, it says I have 0 space left on the Pool, but lvs is reporting that only 43% is allocated data.



Im running the following versions of drbd:

drbd-utils                     8.9.4-1                        amd64        RAID 1 over TCP/IP for Linux (user utilities)

drbdmanage               0.91-1                         amd64        Distributed configuration management for DRBD

As it is now I'm stuck because I can't add any more disks to the pool, please help!
