Public bug reported: Hello speed of execution of reshape and chunk under Ubuntu version 20.04.2.
The execution speed of the "reshape" and "chunk" actions of the MDADM command is much too slow :(speed = 288K / sec). The IOTOP command also indicates that the flow is very low. There is nothing visible with the journalctl command. It will take more than six hours to process a raid of 30 GB. So probably a month if the raid is 4 TB! In addition these commands have no effect sudo sysctl -w dev.raid.speed_limit_min=50000 && sudo sysctl -w dev.raid.speed_limit_max=500000 && cat /proc/sys/dev/raid/speed_limit* 500000 50000 The problem is also visible in this french discussion: https://forum .ubuntu-fr.org/viewtopic.php?pid=22416407#p22416407 Please provide a solution. ** Affects: mdadm (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1916019 Title: speed of execution of reshape and chunk.
