[DRBD-user] Seek help

[Ravi Sankar]

 Dear Support,

I would like to introduce myself,Ravi,working as DBA,located in Singapore.
We recently hit an issue with DRBD after upgrade kernel,unable to mount
DRBD.

Kindly refer below details of our env.

OS-Rhel 6.2,kernel 2.6.32-220
Kernel Upgrade to  2.6.32-754
Current DRBD version-8.3.12

Based on the above info,can kindly shed some light?.Please advice any
compatibilty issue with Kernel update?.
After switch back to original kernel version,we were able to bring up DRBD.

Would really appreciate your inputs.


Following is the DRBD error log.
