DRBD userspace tools need to be updated
Last modified: 2023-03-25 06:56:14 CET
+++ This bug was initially created as a clone of Bug #32019 +++ The DRBD userspace tools in UCS are in version 8.3.11. Since Linux 3.9 the DRBD kernel module requires at least a 8.4 userspace. 8.4 isn't packaged in Debian yet: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=714210 ====================================================================== The DRBD userspace tools in UCS are in version 8.4.4 but the Kernel module is 8.4.5. This probably results in a kernel crash --- Jun 29 07:51:27 server13 kernel: [73672.432083] drbd kopano: PingAck did not arrive in time.

See also Forum-Thread → URL-Field above.
BTW: As mentioned in forum posting, the UCS version is 4.1-4, not 3.0 as per the version field above. Pls update!
Version in 4.2: 8.9.2~rc1 Version in 4.3: 8.9.10-2 -> Fixed
The userland utilities are indeed updated to the versions mentioned in comment #2 in UCS 4.2 and 4.3. -> VERIFIED
