| |
I have tried to burn a cd with cdrecord but all I manage to do was trash one after another. The problem was that I could not keep the fifo filled with data. Considering that I have the image on a raid0 with both disk the same and each can deliver 20MB read per second and the fifo set as hi as 20MB and niced the process to -20 that is a bit suprising.
It turns out that the error happens after 300-330MB every time and I have 384MB ram. So I created a swapfile and like magic the problem was gone have so far done 5 dummy writes and none failed even with the default 4MB fifo.
So do not run linux without some swap space my system have only sawpped out 2MB but without that the system seams to missbehave badly(very badly as the 20MB fifo should protect me for 15-20 seconds).
PS something is wrong in the IDE driver. hdparm -t gives really low values for me, half what it should be and md0(raid0) gives the same value as one of the disks, used to be more like 190%.
