Bug Description
[Impact]
* Multipath from precise proves to have problems with failover
* This can lead to bad I/O if openstack relies on VNX, for example
* "failed/online" path status is NEVER good and I/O corruption can happen
* Minimum can happen is a GUEST freeze if relying on path in question
* Other applications might suffer the same
[Test Case]
* Described fully in comment #3 (comments #1 and #2 are related)
[Regression Potential]
* This patches are the exact change that happen in Precise -> Trusty
development. No major changes or versions were made.
* A PPA with a hotfix was created in order to test those changes and
proved to fix the initial problem.
[Other Info]
Original BUG Description:
Precise multipath-tools MIGHT need fixes from trusty. This has already been proved in one iSCSI multipath installation where precise multipath, intermittently, connected to VNX storages show paths as: active/failed when it should show - even after the path check timeout - faulty/failed.
* Improve description showing output *
Using trusty multipath in Precise, the same environment does NOT suffer
from this issue.
