[Bug 1520192] Re: multipath-tools from Precise should have been fixed together with Trusty fixes
Steps taken to provoke the problem: 1.) deploy any VM instance using nova commands, that is booted from EMC VNX series SAN connected to compute using iscsi, dm-multipath 2.) unplug/disable network connectivity on any of the active paths 3.) check multipath -ll output for faulty failed path/device status. 4.) re-plug/enable network connectivity on the disabled paths 5.) check multipath -ll output for recovering to active enabled path/device status Somtimes the problem occurs when disabling the interface, other times only when re-enabling it. Expected output for multipath -ll: 36006016047813400dd029f614896e511 dm-3 DGC ,VRAID size=50G features='0' hwhandler='1 alua' wp=rw `-+- policy='round-robin 0' prio=70 status=active |- 6:0:0:15 sdi 8:128 active ready running |- 7:0:0:15 sdk 8:160 active ready running |- 8:0:0:15 sdm 8:192 active ready running `- 9:0:0:15 sdo 8:224 active ready running Actual output (even after several hours of waiting, with active traffic on storage): 36006016047813400dd029f614896e511 dm-3 DGC,VRAID size=50G features='0' hwhandler='1 alua' wp=rw `-+- policy='round-robin 0' prio=70 status=active |- 6:0:0:159 sdi 8:128 active ready running |- 7:0:0:159 sdk 8:160 failed ready running |- 8:0:0:159 sdm 8:192 active ready running `- 9:0:0:159 sdo 8:224 failed ready running A previously discovered workaround for the problem can be achieved by reloading the multipath-tools service (or restarting, but multipath -r does not always fixes it). The package with backported changes is confirmed to fix the issue, without having to reload the service. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to multipath-tools in Ubuntu. https://bugs.launchpad.net/bugs/1520192 Title: multipath-tools from Precise should have been fixed together with Trusty fixes To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/multipath-tools/+bug/1520192/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

** Summary changed: - Precise multipath-tools from precise should have been fixed together with Trusty fixes + multipath-tools from precise should have been fixed together with Trusty fixes ** Summary changed: - multipath-tools from precise should have been fixed together with Trusty fixes + multipath-tools from Precise should have been fixed together with Trusty fixes ** Description changed: 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 - 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.
