| Yedidyah Bar David | 2017-02-22 09:00:56 UTC | Doc Text | Cause: In previous versions, host-deploy added a udev rule to change the default I/O scheduler to 'deadline', because the then-default scheduler was not adequate. This rule used 'RUN', to run a command to set the default. Some storage vendors have recommendations to set other specific schedulers for their devices, some of which using 'ATTR', a sysfs attribute. udevadm scans all the files in /etc/udev/rules.d, then first sets all the ATTR configurations, and then runs and the RUN commands. Consequence: It was impossible to follow such storage vendors' recommendations successfully, as our rule would override them. Fix: With RHEL7, the default is 'deadline', so our rule is not needed anymore. host-deploy was changed to not add this rule, and to remove the conf file it added in the past if found. Result: It should now be possible to successfully set I/O schedulers as needed also using ATTR. | |
