Здравствуйте.

Сервер на t6 бранче. Софтовый рейд
# cat /proc/mdstat
Personalities : [raid1]
md2 : active raid1 sdb3[2] sda3[0]
      463822039 blocks super 1.2 [2/2] [UU]
     
md1 : active raid1 sdb2[1] sda2[0]
      20474752 blocks [2/2] [UU]
     
md0 : active raid1 sdb1[1] sda1[0]
      4088384 blocks [2/2] [UU]

Умер диск sdb. Т.к. с дисками напряженка, то заменили на то что было.
Получилось:
# hdparm -i /dev/sda

/dev/sda:

Проблема в том, что скорость записи на sdb раза в 6-7 раз ниже чем на
sda. Смотрю с помощью atop и hdparm
# hdparm -tT /dev/sda
/dev/sda:
 Timing cached reads:   1124 MB in  2.00 seconds = 561.60 MB/sec
 Timing buffered disk reads: 234 MB in  3.00 seconds =  77.99 MB/sec

# hdparm -tT /dev/sdb

/dev/sdb:
 Timing cached reads:   1094 MB in  2.00 seconds = 546.74 MB/sec
 Timing buffered disk reads:  34 MB in  3.14 seconds =  10.82 MB/sec


Хоть и пишут что это диск с размером сектора 512 байт, но я думаю что
проблема с выравниванием раздела имеет место. Т.к. диск размечался с
помощью команды sfdisk -d /dev/sda | sfdisk /dev/sdb для подключения в рейд.

Вопрос: Как быть в такой ситуации? Можно ли разбить диск вручную с
учетом выравнивания раздела и потом добавить в рейд? Я так понимаю что
размер разделов будет не идентичный. Как быть в этом случае?
Может есть другие причины медленной работы диска?

# fdisk -l

На пятисотках не делали 4k-сектор вроде, от терабайта и выше.
Возможно, просто битый диск.

При том битый тот, с которого чтение. Когда посыпался Raid1 копирование со старых дисков раздела в 500 гигов заняло трое суток. Потом с нового на новый все за 4 часа под нагрузкой скопировалось.

Вообще серия WD RE4 пока вроде бы идёт без Advanced Format.

Если в этот момент диск не загружен ничем (например, синхронизацией RAID),
и такие результаты повторяются - вероятнее всего, это плохой диск, который
необходимо заменить.  На самом деле даже диск с 4K секторами показал бы на
последовательных обращениях, тем более по чтению, вполне нормальную
скорость - тормоза там проявляются главным образом при невыровненной
записи.

На всякий случай проверьте, нет ли ошибок в dmesg, ну и смотрите вывод
smartctl -x /dev/sdb (хотя в подобных случаях там может и не быть ничего
подозрительного).

Разбивать диски настолько впритык не стоит - как минимум может иметь смысл
не залезать за официально заявленный размер в десятичных гигабайтах (в
данном случае это 976562500 секторов), иначе в случае необходимости замены
на диск другого производителя места может не хватить (например, некоторые
модели Samsung не давали ни одного лишнего байта сверх заявленной ёмкости
в "малых" гигабайтах).

В случае необходимости выравнивания "здесь и сейчас" в принципе можно
выровнять разделы хотя бы на 4К (8 секторов), сместив их ближе к началу
диска, но сохранив размеры:

  sdb1        56    8177077  (-7)
  sdb2   8177080   49126764  (-5)
  sdb3  49126768  976773165  (-2)

Правда, от этого могут возникнуть некоторые проблемы с загрузкой с такого
RAID (поскольку расположение разделов на дисках не будет совпадать), но
вроде бы lilo поддерживает такой вариант (придётся использовать параметр
raid-extra-boot=mbr).

Т.е. все склоняются к мысли что это не проблема 4к.
Меня в выводе hdparm -i /dev/sdb не понятно почему
BuffSize=unknown

Т.е. нету буфера? Может ли это быть ошибка hdparm? Как-то можно это
проверить? Какие аргументы можно провести продавцу для замены?

При этом SMART девственно чистый. См вложение.
В dmesg из подозрительного только вот это
