Public bug reported: This is a duplicate of the bug listed here: https://bugs.launchpad.net/bugs/1569925 for 16.04.
That bug was automatically closed though the problem still persists. I am opening this bug for 16.10 in hopes that it will catch somebody's attention. I have 4 servers running the latest 16.10 updates. Each server is connected to NetApp storage using iscsi software initiator. There are a total of 56 volumes spread across two NetApp arrays. Each volume has 4 paths available to it which are being managed by device mapper. While logged into the iscsi sessions all I have to do is reboot the server and I get a hang. I see a message that says: "Reached target Shutdown" followed by "systemd-shutdown[1]: Failed to finalize DM devices, ignoring" and then I see 8 lines that say: "connection1:0: ping timeout of 5 secs expired, recv timeout 5, last rx 4311815***, last ping 43118164**, now 4311817***" "connection2:0: ping timeout of 5 secs expired, recv timeout 5, last rx 4311815***, last ping 43118164**, now 4311817***" "connection3:0: ping timeout of 5 secs expired, recv timeout 5, last rx 4311815***, last ping 43118164**, now 4311817***" "connection4:0: ping timeout of 5 secs expired, recv timeout 5, last rx 4311815***, last ping 43118164**, now 4311817***" "connection5:0: ping timeout of 5 secs expired, recv timeout 5, last rx 4311815***, last ping 43118164**, now 4311817***" "connection6:0: ping timeout of 5 secs expired, recv timeout 5, last rx 4311815***, last ping 43118164**, now 4311817***" "connection7:0: ping timeout of 5 secs expired, recv timeout 5, last rx 4311815***, last ping 43118164**, now 4311817***" "connection8:0: ping timeout of 5 secs expired, recv timeout 5, last rx 4311815***, last ping 43118164**, now 4311817***" NOTE: the actual values of the *'s differ for each line above.
