I have the same problem, but an additional noteworthy thing is that the cached reads seems to give the correct result, but the buffered disk reads seem not reset the amount that was read. Thus in subsequent runs you will see the I/O speed linearly increase!!! Timing buffered disk reads: 156 MB in 3.06 seconds = 50.90 MB/sec Timing buffered disk reads: 302 MB in 3.01 seconds = 100.45 MB/sec Timing buffered disk reads: 442 MB in 3.02 seconds = 146.19 MB/sec .... Timing buffered disk reads: 430 MB in 3.00 seconds = 143.12 MB/sec Timing buffered disk reads: 554 MB in 3.03 seconds = 182.81 MB/sec Timing buffered disk reads: 670 MB in 3.00 seconds = 223.07 MB/sec ... initially i thought it would continue to accumulate, but these two triplets of observations were made about 12 hours apart, so clearly the last one at 442MB and 12 hours later at 430MB do show that this buffer does get cleared (partially) from time to time? I have had no chance to test if regular (P)ATA drives suffer from the same problem. I have got the same errors on FC3 of x86_64 platform. # hdparm -tT /dev/sda /dev/sda: Timing cached reads: 2156 MB in 2.00 seconds = 1076.55 MB/sec BLKFLSBUF failed: Operation not supported HDIO_DRIVE_CMD(null) (wait for flush complete) failed: Operation not supported Timing buffered disk reads: 204 MB in 3.01 seconds = 67.83 MB/sec BLKFLSBUF failed: Operation not supported HDIO_DRIVE_CMD(null) (wait for flush complete) failed: Operation not supported My Hardwares: CPU Athlon64 3400+ MotherBoard GA-K8VT800M HDD WD740GD(Raptor) *** Bug 142121 has been marked as a duplicate of this bug. *** *** Bug 172764 has been marked as a duplicate of this bug. *** |
From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; rv:1.7.3) Gecko/20041020 Firefox/0.10.1 Description of problem: When performing, as root, hdparm -tT /dev/sda, I get several 'operation not supported' messages during the benchmarks relating to 'BLKFLSBUF' and 'HDIO_DRIVE_CMD(null)'. As I recall, this didn't happen with FC2. My hardware is: Motherboard: ASRock K7S8XE+ (onboard SiS 180 SATA/PATA controller) Harddisk: Samsung SP0812C SATA Version-Release number of selected component (if applicable): hdparm-5.7-2 How reproducible: Always Steps to Reproduce: 1. Log in as root. 2. Type: hdparm -tT /dev/sda. 3. Wait for the benchmark to perform. Actual Results: [root@cpc1-whit1-5-0-cust140 ~]# hdparm -tT /dev/sda /dev/sda: Timing cached reads: 1020 MB in 2.00 seconds = 508.81 MB/sec BLKFLSBUF failed: Operation not supported HDIO_DRIVE_CMD(null) (wait for flush complete) failed: Operation not supported Timing buffered disk reads: 356 MB in 3.02 seconds = 117.86 MB/sec BLKFLSBUF failed: Operation not supported HDIO_DRIVE_CMD(null) (wait for flush complete) failed: Operation not supported Expected Results: No error messages at all.
