Dear List,
Someone told me when a disk receive a
write request, it write to the nearest free space on disk where the disk
read/write head is currently positioning, is this information correct?? If this
is true, is this a bad thing for database application?? That mean we can't
really control where the file go, for performance purpose we may want to put
certain files on the outer tracks of a disk, if the write location is depending
on where the read/write head is, how can we avoid that, can we create subdisks
from the outer track of a disk and create a logical volume from
it??
