Hallo Peter Osterlund ,
The disc must be formatted for packet writing with cdrwtool before you can put a filesystem on it. If you already have a disc with a udf filesystem,
Thanks, now it get it to work making an ext2-fs.
Speed-issues: Yesterday i made another try with udf, on a fresh 700MB 4x
The udf filesystem seems to be inefficient at handling many small files. I
The pktcdvd module is bypassing the the I/O elevator when creating write requests for the CDRW drive. This can make performance really suffer when
i copied the linux source-tree to the cdrw with ext2-fs now. My experiences on 'cp -a /usr/src/linux/* /mnt/cdwriter': After a short time my system 'freezes' nearly completely for about 15 minutes. That means, i couldn't use keyboard nor mouse, even the LED's numlock on the keyboard wouldn't react of the num-key. But the cdrw was blinking and was written obviously; and the system was allways working as an internetrouter for my son's windows-pc. Then at first i get back the mouse (i did that all under kde3, in some xterms); after some additional minutes the keyboard. This freeze never happened when copying to udf-fs. The whole copying-time was about 30 minutes. Another problem (or is that normal using ext2?): mounting the cdrw (after writing to it) in my cdrom instead of the burner, i couldn't see any files. Copying back the source-tree from the cdrw to /tmp/test works perfectly, without any read-errors or breaking the cp. But a diff between the copy in /tmp/test and the orginal in /usr/src/linux gives about 30 files not identically
there is a mixed read/write load. The 2.5 version of pktcdvd has fixed this problem, but a backport is not easy because it relies heavily on the new bio infrastructure in 2.5.
Is the 2.5 kernel worth a try? I'm running no system with special hardware, only a standard-pc with duron 800, matrox 100 and symbios-logic scsi. Would it be stable on this platform? What about the corrupted files? Is that managed in this version? Greetings-- Email:KOALASOFT@GMX.DE
