The following reply was made to PR i386/29315; it has been noted by GNATS.

The results of these tests show that: (simply checked by "grep MD5 chkcp.txt") 1. Intel ICH2 ATA driver (UDMA5 mode) + Seagate-ST320413A -> OK please see: http://cc.kmu.edu.tw/~cch/FreeBSD/ata/intel-ich2-udma5-hd.txt 2.Promise ATA100 driver (UDMA5 mode) + IBM-DTLA-307030 -> FAIL (It sometimes works correctly, but incorrectly at most time.) please see: http://cc.kmu.edu.tw/~cch/FreeBSD/ata/promise-udma5-hd.txt 3. Promise ATA100 driver (UDMA5 mode) + IBM-DTLA-307030 * 2 (vinum - raid0) -> FAIL please see: http://cc.kmu.edu.tw/~cch/FreeBSD/ata/promise-udma5-vinum0.txt 4. Promise ATA100 driver (PIO mode) + IBM-DTLA-307030 *2 (vinum-raid0) -> OK (But it's too too slow!) please see: http://cc.kmu.edu.tw/~cch/FreeBSD/ata/promise-pio-vinum0.txt Test 1 has been done on machine PC-A. Test 2 has been done on machine PC-B. Test3 and Test4 has been done on PC-C. PC-B and PC-C have the same hardware configuration except different number of hard disks. --------------08D908B015FCF9827134B2E2 Content-Type: application/x-sh; name="chkcp.sh" Content-Transfer-Encoding: 7bit Content-Disposition: inline; filename="chkcp.sh" #!/bin/sh # # This script tests large file copying on FreeBSD/i386 with ATA hardisk # sample=/kernel.GENERIC nrun=10 sleep_unit=0 src=fsrc.tmp dst=fdst.tmp log=chkcp.txt echo "Large File Copy Testing begins (`date`)" > $log # get some of hardware and file system configuration # echo "" >> $log grep -i ata /var/run/dmesg.boot >> $log echo "" >> $log mount >> $log echo "" >> $log df >> $log echo "" >> $log sysctl -a | grep hw.ata >> $log # tests for file size: (sample file size) * {10,100,1000} # for count in 10 100 1000 do # generate source file for copying # echo "" >> $log cat $sample > $src i=0 while [ $i -lt $count ] do cat $sample >> $src i=`expr $i + 1` done echo "src: `ls -l $src`" >> $log md5 $src >> $log echo "" >> $log #sync;sleep 60;sync;sleep 30 # tests copying # i=0 while [ $i -lt $nrun ] do echo "-- Run $i begins (`date`)" >> $log echo " - cp begins (`date`)" >> $log cp $src $dst echo " - cp ends (`date`)" >> $log #sync st=`expr $i \* $sleep_unit` #sync echo " sleep $st seconds" >> $log sleep $st echo " dst: `ls -l $dst`" >> $log echo " - md5 begins (`date`)" >> $log echo " `md5 $dst`" >> $log echo " - md5 ends (`date`)" >> $log #sync echo "-- Run $i ends (`date`)" >> $log echo "" >> $log i=`expr $i + 1` done done echo "Large File Copy Testing ends (`date`)" >> $log --------------08D908B015FCF9827134B2E2-- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
