[Bug 1615694] Re: [860730] Host experiencing constant session termination and recreation while using jumbo frames
Hi Christian, sorry for the delay. We did make an attempt to go back and build from down stream at one point but without much success. We did go ahead and pick up and qualify Ubuntu 18.04 however and are happy to report that the issue appears to be fixed there with the inbox iscsi package 2.0.874-5ubuntu2. I'll attempt to rerun 16.04 with this build here in the near future to see if that doesn't do the trick. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1615694 Title: [860730] Host experiencing constant session termination and recreation while using jumbo frames To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/open-iscsi/+bug/1615694/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Can't say I know how to build from source like that, no.

[Bug 1615694] Re: [860730] Host experiencing constant session termination and recreation while using jumbo frames
Scratch that. I've now reproduced it on debian with the 2.0.874 package. I'd had the time to setup an ubuntu 16.04 host just to sanity check and reproduced it there just to be sure I had the debian configured correctly. By the time I'd returned to it I was seeing the same logouts as ubuntu. Didn't happen as quickly as I'd anticipated on debian, but it's still logging out and logging back in a few times an hour. Let me know how you'd like to proceed from here. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1615694 Title: [860730] Host experiencing constant session termination and recreation while using jumbo frames To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/open-iscsi/+bug/1615694/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I've setup and attempted the reproduction of this defect on debian using the requested 2.0.874 open-iscsi package. The attempts to reproduce have been unsuccessful.It seems like this build may have a fix for our issue. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1615694 Title: [860730] Host experiencing constant session termination and recreation while using jumbo frames To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/open-iscsi/+bug/1615694/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

We're still consistently seeing this issue across any host running iSCSI to an E-Series target.

[Bug 1615694] [NEW] Host experiencing constant session termination and recreation while using jumbo frames
Public bug reported: We're seeing constant iSCSI session terminations and subsequent recreations on Ubuntu 16.04 hosts running IO to an E-Series Array using Jumbo Frames. We've pulled trace of the issue to determine a root cause and discovered that the host appears to be overrunning the Max Command Sequence Number set by the Target. The target is responds to this be killing that session and recreating a new one in it's place as an error recovery mechanism, so the crux of the issue is why the host seems to be falling outside of iSCSI compliance and overrunning the Max Command Sequence Number. This is the reason I went ahead and filed the bug against open-iscsi. Attached are actually two separate traces from two separate recreate, one a Finisar Analyzer Trace, the other a typical TCP dump view-able through wire-shark. I've also attached the Apport data for open-iscsi in case that could be of any use. ** Affects: open-iscsi (Ubuntu) Importance: Undecided Status: New ** Attachment added: "Zip file containing a finisar trace, tcp dump, and apport output for open-iscsi" https://bugs.launchpad.net/bugs/1615694/+attachment/4725797/+files/Defect860730.zip -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1615694 Title: Host experiencing constant session termination and recreation while using jumbo frames To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/open-iscsi/+bug/1615694/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
