Привет,
Возникло ощущение что диск стал медленнее работать.
root@alexey ~ # hdparm -I /dev/sda |grep dma
DMA: mdma0 mdma1 mdma2 udma0 udma1 udma2 udma3 udma4 udma5 *udma
root@alexey ~ # hdparm -c1 /dev/sda
/dev/sda:
setting 32-bit IO_support flag to 1
HDIO_SET_32BIT failed: Invalid argument
IO_support = 0 (default 16-bit)
root@alexey ~ # hdparm -t /dev/sda
/dev/sda:
Timing buffered disk reads: 140 MB in 3.02 seconds = 46.31 MB/sec
Собственно вопрос, эти 46М\с нормально? IO_Support якобы 16 бит (или это
hdparm так врет?). И можно чем-то управлять satroot@alexey ~ # hdparm -t
/dev/sda
/dev/sda:
Timing buffered disk reads: 140 MB in 3.02 seconds = 46.31 MB/sec
Собственно вопрос. Нормальны эти 46М\с для сата, врет ли Hdparm насчет
16bit IO и чем можно управлять сата (если можно уже) ныне?
