Вот, что выдает hdparm относительно его текущих параметров
/dev/hda: multcount = 16 (on) IO_support = 1 (32-bit) unmaskirq = 1 (on) using_dma = 1 (on) keepsettings = 0 (off) readonly = 0 (off) readahead = 16 (on) geometry = 16383/255/63, sectors = 40020664320, start = 0
Все,казалось бы, нормально, НО # hdparm -tT /dev/hda
/dev/hda: Timing cached reads: 2028 MB in 2.00 seconds = 1013.14 MB/sec Timing buffered disk reads: 6 MB in 4.17 seconds = 1.44 MB/sec
Е-МОЕ!!!!
В то время как на другом диске (SATA) той же машины: # hdparm -tT /dev/sda
/dev/sda: Timing cached reads: 1740 MB in 2.00 seconds = 869.70 MB/sec HDIO_DRIVE_CMD(null) (wait for flush complete) failed: Inappropriate ioctl for device Timing buffered disk reads: 162 MB in 3.00 seconds = 53.99 MB/sec HDIO_DRIVE_CMD(null) (wait for flush complete) failed: Inappropriate ioctl for device
В логах никаких ошибок. Что бы это могло быть???
