[Group.of.nepali.translators] [Bug 1815201] Re: mdadm checkraid cronjob runs at the same time
Ubuntu 19.04 reached end of life on January 23, 2020. I am therefore marking this bug 'wontfix' for that release. ** Changed in: mdadm (Ubuntu Disco) Status: Triaged => Won't Fix ** Changed in: mdadm (Ubuntu Cosmic) Status: New => Won't Fix -- You received this bug notification because you are a member of नेपाली भाषा समायोजकहरुको समूह, which is subscribed to Xenial.

[Group.of.nepali.translators] [Bug 1815201] Re: mdadm checkraid cronjob runs at the same time
This bug was fixed in the package mdadm - 4.1-2ubuntu3 --- mdadm (4.1-2ubuntu3) eoan; urgency=medium * Drop /etc/cron.d/mdadm and migrate to systemd mdcheck_start|continue timer units. * Drop /etc/cron.daily/mdadm and migrate to system mdmonitor-oneshot timer unit. * mdcheck_start.timer configures the mdcheck on a first sunday of the month, with a randomized start delay of up to 24h, and runs for at most 6h. mdcheck_continue.timer kicks off daily, with a randomized start delay of up to 12h, and continues mdcheck for at most 6h. * mdmonitor-oneshot.timer runs daily, with a randomized start delay of up to 24h. * One can use systemd drop-ins to change .timer units timings, set environmental variables to decrease/increase the length of checking, or start the checks by hand. Previously used checkarray is still available, albeit not used by timer units. * Above ensures that previous daily / monthly checks are performed, but are randomized, such that performance is not as impacted across a cluster of machines.
