Hello,develop team.I test multipath in RHEL 6.2(X86_64).I find a issue when test takeover.There are 8 disk in one target path;7 disk is active,but 1 is faulty(mpathf).I check target ,and there is well;I didn't how can i avoid the issue. I find some different between active and faulty var /var/log/message.The mpathf print "map in use,unable to flush devmap".Is there some helpful?
