Message-ID: <43D55876.5020800@ula.ve> (raw)
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? Thank a lot in advance
Best regards
Gilberto Diaz
