[Group.of.nepali.translators] [Bug 1634161] Re: Default multipath policy is round-robin, shows considerably worse read throughput compared to using service-time

2017-03-18 Thread Launchpad Bug Tracker

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. (LP: #1634161)
