Title:
IPR driver causes multipath to fail paths/stuck IO on Medium Errors
Status in linux package in Ubuntu:
Triaged
Status in linux source package in Xenial:
Fix Committed
Status in linux source package in Zesty:
Fix Released
Bug description:
SRU Justification:
Impact: stuck I/O to multipath disks with medium errors (on IPR controllers)
Fix: upstream commit for IPR driver to allow SCSI layer to handle the error
Testcase: perform I/O to a failing disk which is multipathed (on IPR
controller), which returns SCSI Medium Errors (without the fix,
the I/O gets stuck).
the commit message describes a test-case w/ sg_dd.
---Problem Description---
IPR driver causes multipath to fail paths/stuck IO on Medium Errors
This problem is resolved with this upstream accepted patch, scheduled for
4.11.
The detailed problem description and resolution are described in the commit
message.

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=785a470496d8e0a32e3d39f376984eb2c98ca5b3
Please apply to 17.04 (target 16.04.3 HWE kernel) and 16.04 (GA kernel).
Patch already applied to 17.10.
The business justification for the SRU is:
Clients with a dual-controller multipathed IPR configuration that
eventually runs into failing disk/sectors, will experience an I/O hang
once the drive reports a Medium Error, which can hang an application
or even the root filesystem (whatever is doing I/O to the failing
drive), potentially hanging the system.
Thanks.
---Additional Hardware Info---
Dual (IPR) controller setup, multipath enabled
---Steps to Reproduce---
1) Use a disk with bad sectors (or force such condition, via internal/special
tools)
2) Multipath that disk
3) Run IO to the multipath device on the bad sectors
4) Both paths will be failed, and IO is stuck due to queue_if_no_path
(enabled by default for IPR)
The detailed problem description and resolution are described in the
commit message.
