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. This seems like a bug somewhere but I am unaware of any additional logging that I could turn on to pinpoint the problem. Note I also have similar setups that are not doing iscsi and they don't have this problem. Here is a screenshot of what I see on the shell when I try to reboot: https://www.dropbox.com/s/93mv7cj8asspcpa/ShutdownCapture.JPG?dl=0 This is being tracked in NetApp bug tracker CQ number 860251. If I log out of all iscsi sessions before rebooting then I do not experience the hang: iscsiadm -m node -U all We are wondering if this could be some kind of shutdown ordering problem. Like the network devices have already disappeared and then iscsi tries to perform some operation (hence the ping timeouts).
