Your comments below are thoughts on the PATA RAID1, not the one which is
giving trouble, the SATA. Unless you think that making the working array
faster, perhaps he's looking for ideas on fixing the array which isn't
working as expected.
My main question:
Why the 'heck' are you running a RAID1 with a master/slave
combination? That is probably the -worst- way to run it. When using
any form of RAID, make sure you do not share an IDE channel for any
one raid device.
Advice? Hook up each drive as a master, then your rebuild speed
should go to 30-60MB/s.
Traditional Troubleshooting:
What does fdisk -l /dev/hda
fdisk -l /dev/hdb
Report?
Also,
What does:
smartctl -a /dev/hda
smartctl -a /dev/hdb
show?
Then,
smartctl -t short /dev/hda
smartctl -t short /dev/hdb
Wait 5-10 minutes, re-run the commands (-a) above.
Then,
smartctl -t long /dev/hda
smartctl -t long /dev/hdb
Then re-run the (-a) smartctl above.
--------
Those errors look really weird, I would separate the two disks, each
on their own IDE channel and see if your problem goes away.
Justin.
