RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

This bug is to deal with multipath allowing fast_io_fail_tmo to work with iscsi devices.

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?
