Szukam pomocy żeby zmusić debiana żeby widział raid0 a nie osobne 2 dyski
Sprzęt ajki posiadam:
IBM xSeries 306
Kontroler adaptec aic-7901x
fdisk -l
Disk /dev/sdb: 18.2 GB, 18210037760 bytes 255 heads, 63 sectors/track, 2213 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x00000000 Disk /dev/sdb doesn't contain a valid partition table Disk /dev/sda: 18.2 GB, 18210037760 bytes 255 heads, 63 sectors/track, 2213 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x00000000 Disk /dev/sda doesn't contain a valid partition table Disk /dev/hda: 80.0 GB, 80026361856 bytes 255 heads, 63 sectors/track, 9729 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x145c145b Device Boot Start End Blocks Id System /dev/hda1 1 851 6835626 83 Linux /dev/hda2 852 9729 71312535 5 Extended /dev/hda5 852 1181 2650693+ 82 Linux swap / Solaris /dev/hda6 1182 9729 68661778+ 83 Linux
Wszytko już w kernelu włączyłem i dalej nic. Dzieki dmraid pokazał
dmraid -r cl->raidtype=0 rd_type=32 cl->raidtype=0 rd_type=32 /dev/sda: asr, "asr_squid", stripe, ok, 35545088 sectors, data@ 0 /dev/sdb: asr, "asr_squid", stripe, ok, 35545088 sectors, data@ 0
i zrobiłem nim partycję ale to jest softwarowy raid i prędkość jest taka sama jak 1 dysku
/dev/dm-0: Timing buffered disk reads: 112 MB in 3.01 seconds = 37.25 MB/sec
Nie chcę instalować na tym raidzie systemu chcę go wykorzystać do squida.
Ale już się poddałem po 2 dniach walki

Zrezygnuj z dmraid i zrób raid za pomocą mdadm - http://pl.docs.pld-linux.org/soft_raid.html

No ok ale jak mam raid sprzętowy to chciał bym go wykorzystać pewnie będzie lepszy od softu

napewno będzie leprzy ,sprawdź konfiguracje raidu bo aż mi sie wierzyć nie chce że pomimo włączonego raid debian widzi 2 dyski

Na 100% już 2 dni walczę kontroler pokazuje 1 dysk 36gb a debian 2 dyski po 18gb

Jakby to był w pełni sprzętowy raid, to po skonfigurowaniu macierzy w biosie kontrolera, debian widziałby jeden dysk - nie byłoby konieczne stosowanie dmraid=true
Jak poszukałem o tym kontrolerze w necie, to wyczytałem, że jest to fakeraid w wykonaniu SCSI - kontroler ma zmodyfikowany bios, przesyłający metadane do sterownika, który odwala za niego całą robotę (czyli procesor) http://lists.freebsd.org/pipermail/freebsd-scsi/2004-April/001126.html
"Prawdziwy" raid sprzętowy, oprócz oczywiście biosu posiada własny procesor wykonujący operacje związane z obliczaniem sum kontrolnych, ma hot-plug, zarządzanie macierzą przez linie poleceń.
W twoim przypadku gdy musisz korzystać z dmraid - mdadm jest wydajniejszym rozwiązaniem, dodatkowo raid ten będzie działał na innym kontrolerze scsi.

No to kicha mam jeszcze jeden serwer tylko że pIII ale na nim kiedys robiłem raida 5 wiec chyba ma już normalny kontroler muszę go odkopać i ciszej będzie pracował niż ten

Jaka co kicha? Softwarowy raid w kernelu jest prosty do konfiguracji, szybki (miałem na komputerze w domu raid 0 prawie 2 x pojedynczy dysk), zero problemów. Spróbujesz - zobaczysz. Zawsze możesz przełożyć kontroler ze starego - tyle, że w ogólnym rozrachunku wydajność może być słabsza (wolniejszy kontroler, w przypadku dołożenia dysków - wolniejsze dyski).

Kicha uważasz to za super prędkość 2 dyski SCSI w raid0 oczywiście zrobione programem MDADM
Timing buffered disk reads: 112 MB in 3.01 seconds = 37.25 MB/sec
Dysk ATA
/dev/hda: Timing buffered disk reads: 122 MB in 3.06 seconds = 39.92 MB/sec
Rewelacji nie ma

Właściwie kicha, taką prędkość ma dysk w 15 letnim Proliancie, wklej wynik dmesg i lsmod.

Posprawdzaj czy kable są w porządku, czy dyski czasem nie mają skonfigurowanych przez zworki jakiś dziwnych ustawień (czasami dyski mają zworki po drugiej stronie złącza scsi), czy taśmy SCSi są zakończone terminatorem (czasami nie łączy, wysuwa się).
Z innych pomysłów: zbootowanie sytemu z jakiegoś nowszego jadra nawet z backportów może jest jakiś bug..., ale stawiam na sprzęt.

Bardzo dziwne bo kable SCSI powinny być zakończone terminatorem, może masz go w złym miejscu, powinno być tak:
[kontroler]---[dysk,lub wolne złącze]---[dysk, lub wolne złącze]---[dysk, lub wolne złącze]---[terminator]
Kontroler już zawiera terminator, tylko stare dyski SE (max 40MB/s) miały terminator włączany zworką.
Jakie są to dyski (producent model)?, nie masz czasem dysków SE?, tu masz link do przyzwoitego artykułu o magistrali SCSI i urządzeniach http://www.pcworld.pl/artykuly/39173_0_1/SCSI.LVD.html

Witam
Dodam jeszcze jak podłącze jeden dysk to prędkość jest ok. Sprawdzałem już różne dyski i zawsze przy większe ilości max 3 chcę podłączyć to prędkość jest niższa. Nie wiem może kontroler sobie dzieli tą prędkość na ilość dysków??
Sprawdzałem na innym serwerze IBM ze sprzętowym raidem to tak samo jest niższa prędkość

A sprawdzałeś obydwa dyski czy pojedynczo pracują z odpowiednią prędkością? Bo taki objaw występuje jak kontroler SCSI przełącza magistralę w tryb SE - wystarczy że jeden dysk będzie pracował w trybie SE i już kontroler zwolni magistrale do niego, to samo będzie jak na taśmę założysz terminator SE a nie LVD.
Coś nie podoba mi się ten terminator, bo wcześniej pisałeś, że dyski działały szybciej bez terminatora a powinno być dokładnie odwrotnie.
