[Bug 1634161] Re: Default multipath policy is round-robin, shows considerably worse read throughput compared to using service-time
This bug was fixed in the package multipath-tools - 0.6.4-3ubuntu2 --- multipath-tools (0.6.4-3ubuntu2) zesty; urgency=medium * debian/initramfs/hooks: - Remove old dm-emc module; it hasn't been in kernel since 2.6.27. - Add dm-queue-length: users may want to change from the default selector and should be able to do so. (LP: #1673350) * debian/patches/path_selector.patch, debian/patches/series: remove path_selector.patch to get back to the "right" default selector of service-time, which has been included in the kernel module packages for a while now and has better throughput than round-robin. It's also the default upstream.

[Bug 1634161] Re: Default multipath policy is round-robin, shows considerably worse read throughput compared to using service-time
I wonder if we can check if this is still the case; and if we can build round-robin udeb yet service-time deb. Furthermore, it might make sense to make sure relevant kernel modules are available as udebs. ** Changed in: multipath-tools (Ubuntu) Assignee: Skipper Bug Screeners (skipper-screen-team) => Dimitri John Ledkov (xnox) ** Changed in: multipath-tools (Ubuntu) Status: New => Confirmed ** Changed in: multipath-tools (Ubuntu) Milestone: None => later ** Changed in: multipath-tools (Ubuntu) Importance: Undecided => Low -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1634161 Title: Default multipath policy is round-robin, shows considerably worse read throughput compared to using service-time To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-z-systems/+bug/1634161/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1634161] Re: Default multipath policy is round-robin, shows considerably worse read throughput compared to using service-time
FYI the minimal bits I checked in the background when we talked about it yesterday. Done in debian/patches/path_selector.patch Related Changelog: * debian/patches/path_selector.patch: switch the default path selector back to round-robin while service-time isn't available to the installer multipath-modules. Likely starts by fully understanding the old dependencies that got to the decision to add that. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1634161 Title: Default multipath policy is round-robin, shows considerably worse read throughput compared to using service-time To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-z-systems/+bug/1634161/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
