Ok sorry, I thought you had a need for some of the features in Giant, using
tunables is probably easier in that case.
I'm not sure :) I never played with the tunables before (still running
a testbed only)
I will test it again with 14.04.2 and default kernel beginning of next
year, I prefer to use the "official" kernel for the production
cluster, but since it's going to be deployed Q1-Q2 next year I should
be safe.
I use aptly to manage my repositories and mix and match (and snapshot /
pin) specific versions and non-standard packages, but as far as I know,
the kernel from utopic unicorn is already in the main repositories for
trusty and is a 3.16 line.
apt-cache policy linux-image-generic-lts-utopic
should give you the information about availability in your repository.
My information is:
linux-image-generic-lts-utopic:
Installed: (none)
Candidate: 3.16.0.25.19
Version table:
3.16.0.25.19 0
500 http://security.ubuntu.com/ubuntu/ trusty-security/main
amd64 Packages
Note the "lts" in the name, these are officially supported although they
don't specifically announce those kernels when they become available or
I'm not on the correct mailing lists for that. Generally about one to
two month after a new non-lts release, they will be there for the LTS
version.
Plus you can always grab "pre-release" versions from the kernel-ppa
location that was given below.
Kind regards
René

However if you do want to upgrade there are debs available:-
http://kernel.ubuntu.com/~kernel-ppa/mainline/
and I believe 3.16 should be available in the 14.04.2 release, which should
be released early next year.

This is probably due to the Kernel RBD client not being recent enough.
Have you tried upgrading your kernel to a newer version? 3.16 should
contain all the relevant features required by Giant.
I would rather tune the tunables, as upgrading the kernel would require a
reboot of the client.
Besides, Ubuntu Trusty does not provide a 3.16 kernel, so I would need to
recompile...
