Hi Shweta,
thanks for your findings. I am very much surprised to see this was not
discovered earlier, especially since this feature has been implemented many
versions back (back in version 4.4 or 4.5 i think). I was under the
impression that people are testing and reporting on the new features before
they hit the release, which apparently is not the case, at least for some
new features. From what I can see this feature was completed about a year
ago.
I've tried to reopen this issue, but i don't have the rights due to the
Jira being in a temporary Lockdown mode.
Could someone with the right access reopen this issue on the grounds that
it was reported (by at least two individuals) that this feature is not
working.
Many thanks
Andrei

Subject: RE: KVM disk cache option has no effect
Hi Andrei,
Few days back I was also doing some testing in this area and then we
found out
that cache field in disk offering is just a UI or API parameter. But in
actual
implementation of the API we are just neglecting this parameter . So
effectively these parameters in disk offering does nothing .
Thanks
Shweta

Subject: KVM disk cache option has no effect
Hello
I've been trying to use cache = writeback option for my KVM hypervisor
with ceph
backend storage. However, when I am launching a vm that uses the disk
offering
with cache=writeback, the cache setting is still set to =none according
to the
ps aux command.The same applies to the root as well as additional data
volumes.
I am using ACS 4.7.1, both management and hypervisor servers are Ubuntu
14.04.
Could someone please advise on how enable writeback cache?
Cheers
Andrei
