[Linux-HA] Integrating iSCSI service to DRBD for iSCSI failover

[sajanagr]

Hi

Sorry for replying late.. i had to recreate this situation and generate the
log. I have the full report of the logs. I am uploading the output of
"cibadmin -Q". 
Let me know if any other logs will help, i will upload them. 

Thank you
