Hello, I had a software raid 5 array of 4 disks drop two last night and was
curious of what help I may find.
I have 4 250GB maxtor drives in software raid 5 array and I seem to get the
dma_timer_expiry error comming up every few weeks and I was curious as to
how I may recover what I can from the array.
I am running the array on an Abit AT7 Max motherboard with an AMD 2400XP+
CPU, 1 GB ddr266 ram and a HPT 374 onboard raid controller with 4 channels.
Centos 4.3 with Vanilla Sources (2.6.17) is the current linux flavor.
So far I have left the affected system running without doing anything to it
and was curious where I should start?
Here are the dmesg and at the end the cat/proc/mdtstat outputs:
