Re: Problem: ICH7 stalls on transfer from PATA to SATA
Update: it seems I was off track. Simultaneous reading from a PATA and
SATA drive (diff on 1GB files) does NOT slow down the computer. Also,
and more importantly, file transfers from one SATA partition to another
DOES slow down the computer. Furthermore, a transfer from a SATA
partition to the PATA drive does not slow down the computer.
So it seems my problem is that when the computer wants to WRITE to my
SATA partitions, it come to a near total halt.
My setup is as such...
sdb3 and sdc3 are 10GB each. They are each half of a RAID0 array. They
become /dev/md10. md10 is formatted with XFS. This contains my root
partition.
sdb5 and sdc5 are 220GB each. They are also each half of a RAID0 array
called /dev/md11. This is also formatted with XFS and is a storage
drive mounted in /mnt.
So in short I have partitions on 2 SATA drives RAID0'ed with the XFS
file system and writing large files to these partitions brings the
system to it's knees, but read actions do not.
Anyone have any ideas? Odds are I'll probably forgo the RAID0, as it is
far more of a pain than any performance boost benefit, but I'd like to
figure out what went wrong.
