Hello Everybody I have checked the list archive but I could not find any message that help. So I'm asking for help here. I have a Sun storege with 12 sata hard disks connected to a normal PC using a QLogic ISP2300 host adapter card. I have configured 6 raid1, (2 hard disk each). I excecuted the following commands to create all of the them mdadm --create --verbose /dev/md1 --level=raid1 --raid-devices=2 /dev/sda /dev/sdb mdadm --create --verbose /dev/md2 --level=raid1 --raid-devices=2 /dev/sdc /dev/sdd mdadm --create --verbose /dev/md3 --level=raid1 --raid-devices=2 /dev/sde /dev/sdf mdadm --create --verbose /dev/md4 --level=raid1 --raid-devices=2 /dev/sdg /dev/sdh mdadm --create --verbose /dev/md5 --level=raid1 --raid-devices=2 /dev/sdi /dev/sdj mdadm --create --verbose /dev/md6 --level=raid1 --raid-devices=2 /dev/sdk /dev/sdl Here is my /etc/mdadm/mdadm.conf file DEVICE /dev/sd[abcdefghijkl] /dev/md1 /dev/md2 /dev/md3 /dev/md4 /dev/md5 /dev/md6 ARRAY /dev/md1 devices=/dev/sda,/dev/sdb ARRAY /dev/md2 devices=/dev/sdc,/dev/sdd ARRAY /dev/md3 devices=/dev/sde,/dev/sdf ARRAY /dev/md4 devices=/dev/sdg,/dev/sdh ARRAY /dev/md5 devices=/dev/sdi,/dev/sdj ARRAY /dev/md6 devices=/dev/sdk,/dev/sdl The problem is that the following proccesses are using a lot of cpu time. md1_raid1 md1_resync ...... md6_raid1 md6_resync Here is a sample of the uptime command 17:54:16 up 5:48, 2 users, load average: 5.02, 5.05, 5.26 Does anybody have an idea what is the problem?
