Setting fast_io_fail_tmo will now set /sys/class/iscsi_session/session<n>/recovery_tmo For iscsi devices. This will allow the scsi layer to fail the IO errors back to to multipath sooner. Ben, will we get this version (0.4.9-80.el6) in 6.5z/7.0.z? This already exists in 7.0. You could request a rhel-6 zstream. I have no problem with that, but as far as I know, nobody has requested a zstream version of this fix for rhel-6.5.z Ben, I tested this on rhel 7.0, and I had to manually edit the node files in /var/lib/iscsi/nodes to avoid 2 minutes timeout. # rpm -q device-mapper-multipath device-mapper-multipath-0.4.9-66.el7.x86_64 I guess that this system is not updated, but it is not my system and I don't want to change it. Sean, can you do the needed magic to get it in 6.5.z? Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
