Force server to use all resources for resync

  • 772

I need to resync my RAID and noticed that it isn't a big consumer.
I have booted my system with the Rescue CD and started the resync.

Looking at top it seems that the processes doesn't take much resources.

Can I force the mdadm to use ALL resources for the resync?

cat /sys/block/md0/md/sync_speed_m*
200000 (system)
50000 (system)
mdadm

    It's already using all usable ressources if you don't use it for anything during the resync. This process is nearly only limited by the disk speed on modern systems, so you will see very few other resources being used. If you use a hardware RAID controller, the load to the rest of the system will even be zero, as the RAID controller will do all of the work without any other resources used at all.
