I have setup a sofeware raid-1 on my linux box,
hda1+hdb1 -> md0 (/)
hda5+hdb5 -> md1 (/home)
because hda and hdb are on same IDE controller, the preformance is really bad.
what is the correct procedure to transfer hdb to hdc ?
put the hdb hardisk to hdc and restart the box
than mdadm --assemable /dev/md0 /dev/hdc1
and edit the lilo.conf and raidtab to match the setting
and reboot again.
is it the right way to make better performance with all data safe ?
Thank you very much
