------------------------------------
[~ederevea] AFAIK it will just empty the cache.
Please take a look at '/etc/sysconfig/readonly-root' and '/etc/rwtab'.
They seem to do exactly what we need without having to add our own unit files. They also
add the interesting possibility to move things from disk to RAM on boot. While this is not
mandatory, it will be useful for saving cache warm-up times.
Add disks in memory for lago slaves
------------------------------------
Key: OVIRT-636
URL:
https://ovirt-jira.atlassian.net/browse/OVIRT-636
Project: oVirt - virtualization made easy
Issue Type: Bug
Reporter: eyal edri [Administrator]
Assignee: infra
We need to try moving the Lago slaves in CI to work with memory instead of local disks,
It might speed up the tests significantly.
We have 2 choices:
1. add code to the job and mount the dir on /dev/shm/
2. create zram drive and mount the following dirs on it:
# /var/lib/mock
# /var/lib/lago
# /home/jenkins
Each host should have enough memory to run current tests on them,
however we'll need to make sure to clean that drive after each run.
Lets try it on one of the slaves to see what is the best solution before implementing for
all slaves.
