#351760

Здравствуйте. Поменял хард и замерял скорость кэширования и буферизации hdparm'ом.
[console]# hdparm -tT /dev/sda
/dev/sda:
Timing cached reads: 1294 MB in 2.00 seconds = 646.27 MB/sec
Timing buffered disk reads: 156 MB in 3.02 seconds = 51.67 MB/sec[/console]
При том, что аналогичниый хард выдавал 2000+ МБ и 60+ МБ соответственно. Только за сегодня с каждым замером (интервал в несколько часов) скорость кэширования упала с 1100 МБ до того, что показано выше. Значит ли это, что хард помалу приказывает долго жить? Спасибо.

Для полноты картины посмотрите SMART жесткого диска, это, вероятно, прояснит в чем дело.

#351773

yars, подскажите, пожалуйста, каким образом это можно сделать, если физического доступа к серверу нет и на нем установлен только CentOS.
upd: Нашел утилиту smartmontools. Оно?

#351775

А по ssh запустить smartctl нельзя?

#351782

Получил нечто такое. Пишет что-то об ошибках. Критично ли это?

Внимание на reallocated sector count. Да, имхо менять пора...

#351790

Благодарю. Значит буду менять.
