review request: SDM update_volume API changes
by Germano Veit Michel
Hello,
Could you please review and comment on the following patch series below?
https://gerrit.ovirt.org/#/q/status:open+project:vdsm+branch:master+topic...
These are required by future tools to make fixing image chains safer and
easier.
This has been previously submitted as part of a larger set of patches,
which were not accepted mostly due to a ResourceManager Exception
workaround (force flag). The series above removes that workaround and also
improves the tests.
I'm only submitting the API changes at this time. If you want to have an
idea on what this will be used for, please see now abandoned
https://gerrit.ovirt.org/#/c/94105/ (it will get updated and resubmitted
once and if these API changes are accepted)
Thanks,
Germano

Most el7 vdsm build fail to fetch source - bad slave?
by Nir Soffer
I have see many such failures today, here is 2 bulids - both on same slave
(slave issue?)
1. [2019-06-20T22:23:12.401Z] Running on node: vm0015.workers-phx.ovirt.org
(el7 phx nested local_disk)
https://jenkins.ovirt.org/blue/organizations/jenkins/vdsm_standard-check-...
2. [2019-06-20T22:20:50.288Z] Running on node: vm0015.workers-phx.ovirt.org
(el7 phx nested local_disk)
https://jenkins.ovirt.org/blue/organizations/jenkins/vdsm_standard-check-...
Looks like there was no build on this slave in the last 2 days:
https://jenkins.ovirt.org/computer/vm0015.workers-phx.ovirt.org/builds
The failure looks like this:

export domain bug?
by Hetz Ben Hamo
Hi,
Clicking on compute, templates, the HE complains that the export domain is
not available.
Isn't export domain deprecated and the import window should default to the
a storage domain?
Should I open a bug in Bugzilla?
Thanks

Low Performance Issue
by Akshita Jain
I've setup oVirt HCI over 3 servers.
Each server has 1* 480 GB SSD, 5* 1.8 TB SAS HDD with oVirt version 4.3.3
But I am still able to get low performance.
Can anyone suggest the tuning variables for Gluster volume.
Remark :What should the value be set for network.remote-dio= enable / disable ?

[storage] isolating images
by Germano Veit Michel
Hello,
When there are image chains problems, sometimes it is not possible to
determine the correct chain due to lost information like rotated logs. For
this cases, it is usually desirable to remove a volume from the chain but
not from the storage until the user confirms the VM is healthy and contains
the correct data. Currently this is done by moving files (file storage) or
renaming LVM tags (block storage) so VDSM does not find the particular
volume to be part of the chain.
Ideally I would like to have this done by a vdsm-tool talking to VDSM api.
The tool would be able to mark the volume to be ignored or not, list all
ignored volumes and perhaps even delete them (to free space).
How would you recommend proceeding with such tool? Some ideas:
- Have a reserved image UUID which contains all ignored volumes, so they
are not part of any chain.
- Add an "ignore" metadata attribute to each volume.
I like more the first option, but looking for opinions and ideas.
Thanks,
Germano
