# uname -a
Linux myserver 3.3.4-gentoo #1 SMP Wed May 9 22:58:59 MSK 2012 i686 Intel(R) Pentium(R) 4 CPU 2.80GHz GenuineIntel GNU/Linux

Периодчиески после старта сервера возникают проблемы с дисковым I\O ....

Во время проблемы:

# hdparm -tT /dev/sda

/dev/sda:
Timing cached reads: 2 MB in 5.68 seconds = 360.54 kB/sec
Timing buffered disk reads: 2 MB in 12.76 seconds = 160.50 kB/sec

После перезагрузки все ОК.

# hdparm -tT /dev/sda

/dev/sda:
Timing cached reads: 704 MB in 2.00 seconds = 351.22 MB/sec
Timing buffered disk reads: 286 MB in 3.01 seconds = 95.00 MB/sec


Через несколько перезагрузок проблема вновь появляется вместе с запуском сервера - сервер стартует минут 10 и потом сильные задержки i\o, производительность резко падает. Проблема независит от того, вручную стартую сервер, или через WoL.

Заменил SATA-кабель для диска /dev/sda, но проблема осталась.

Кроме того, проблема с деградацией I\O одинаково проявляется и на PATA диске (/dev/sdb).
SATA-PATA controller SiS.

Sata диск - знаменитый своей интеллигентой "зеленой" частой парковкой головок для уменьшения энергопотребления и улучшения климата нашейпланеты - WDC Green Caviar, у которого таймаут парковки стоит в 8 сек - дефолтовый параметр от WD ("idle3" timeout value).

"This timeout controls how often the drive parks its heads and enters a low power consumption state. "

Поменял этот таймаут в 300сек, но проблема осталась.

# hdparm -J /dev/sda

/dev/sda:
wdidle3 = 300 secs (or 13.8 secs for older drives)

Везде пишут, что эта проблема связана с транспортом от контроллера диска до контроллера матплаты(или карты расширения), или драйвер глючит.

Первое не подтверждается, т.к. кабель был заменен.

В ядре сконфигурено:

CONFIG_SATA_SIS:

x This option enables support for SiS Serial ATA on x
x SiS 964/965/966/180 and Parallel ATA on SiS 180. x
x The PATA support for SiS 180 requires additionally to x
x enable the PATA_SIS driver in the config. x
x If unsure, say N. x

x This option enables support for SiS PATA controllers x

Была подобная проблема, поменял порт SATA в который воткнут HDD, если диск в порядке, то может умер SATA контроллер.
