Dala uhlu lwediski nge-mdadm !!!!!

Ngethula okokufundisa ukudala uhlu lwediski ngisebenzisa uhlelo lokusebenza mdadm (http://packages.debian.org/squeeze/mdadm).

Izidingo zokukwenza ukuthi ube nomshini obonakalayo nge Squeeze Debian nama-disk ambalwa, kulezi zimo ezinamandla we-1 Gb kwanele, ngoba esizokwenza kuzosebenza nge-matrix njll, futhi isibonelo sokugcwalisa idatha, nakho kuyisivivinyo.

Kuleli cala dala i-3, njengoba kubonakala esithombeni, ngaphezu kohlelo:

Siqala umshini, singena njengezimpande bese sifaka uhlelo lokusebenza:

apt-get install mdadm hdparm
o
apt-get -t squeeze-backports install hdparm mdadm

uma sinalezi zindawo zokuphumula emithonjeni yohlu

Ngemuva kokufaka uhlelo, sizoqhubeka nokulungisa amadiski ukuze afakwe kumatrix:

• Okokuqala sibathola nge- "fdisk -l"

•  Lapho kutholakala amadiski, bese siqhubeka nokuyinika ifomethi ehambisanayo, kulokhu sisebenzisa uhlelo lwe-cfdisk:

Lapha kufanele sicacise, kufanele senze le nqubo nge-HDD ngayinye esifuna ukuba kuyo kumatrix. Siqala ukwenza isibonelo nge / dev / sdb:

cfdisk /dev/sdb

•  Sinikeza "Okusha" bese sikukhetha ngokuthi "Okuyinhloko".

• Sihamba ngemenyu bese sishaya u- "Type".

•  Ukuze usebenzise ukwahlukanisa ku-matrix, siguqula uhlobo lwefomethi (sithayipha i-FD).

• Le ndlela okufanele ibukeke ngayo:

• Ngemuva kwalokho sigcina izinguquko:

•  Sihlola wonke amadiski nge-fdisk, ukuqinisekisa ukuthi asilahlekile noma yikuphi ukulungiselela:

Sizoqhubeka nokwakha ifayili elikhethekile, sizoliphatha njengokungathi "liyi-block":

mknod /dev/md0 b 9 0

Ngiyachaza, lo myalo ukudala amafayili «akhethekile», uma siwucela ngepharamitha le- «b» siwutshela ukuthi ukwenze sengathi bekuyibhlokhi, isibonelo salokhu esinaso emafayilini e-HDD yethu, a ls -lh to sd * futhi uzobona:

brw-rw - T 1 impande disk 8, Jul 0 30 07:04 / dev / sda

Kepha kusho ukuthini u-9 0? Njengoba ilula inguqulo, nansi inguquko MAJOR-MINOR, lapho i-9 inguqulo enkulu ye-0 encane, okungukuthi, i-mini language twister.

Sihlola ukuthi sakhiwe ngendlela efanele:

brw-r-r- 1 impande 9, 0 Jul 30 11:12 / dev / md0

Manje sesingadala i-RAID yethu, kepha okokuqala kudingeka sizibuze imibuzo ethile:

• Yimuphi umthwalo wokusebenza ozoba nawo umatrix?
• Ngabe ngizofunda ngaphezu kokukubhalela?
• Ingabe imininingwane oyigcinayo idinga isipele?
• Ingabe kufanele itholakale kakhulu?
• Ngabe ngifuna umthamo noma ukuphepha?

Kule mibuzo vakashela i-Wiki (http://es.wikipedia.org/wiki/RAID), kuya ngohlobo lwe-matrix olukhethayo ukuthi kufanele uqhubeke kanjani, kulesi sifundo, sizokwakha i-raid0, kunezinhlobo ezimbili , okuqondile nokugqaywayo, umehluko wokuthi amadiski afanayo agcwaliswa ngendlela afakwe ngayo ku-matrix, kanye nomugqa lapho amadiski agcwaliswa ngokulinganayo nokuthi futhi kuyashesha ekufundeni / ekubhaleni (inqobo nje ubukhulu bama-disc buyafana).

Asikwenze:

mdadm -C /dev/md0 -N RAID0-STRIPE --level=stripe --raid-devices=3 /dev/sdc1 /dev/sdd1 /dev/sdb1

Ngalokhu sizobe sesidale i-matrix yethu, yokungabaza «man mdadm»:

mdadm -D /dev/md0

Singakwazi ukwengeza ezinye izinto, njengokuthi uma ungeza enye idiski ungaba nayo kumodi "yokuphendula okuzenzakalelayo" lapho enye yalaba abathathu yehluleka, singakwenza lokhu ngenketho "-x / dev / sdN"; Khumbula ukuthi singaba nama-disc amaningi ku- "SPARE" ngendlela esifuna ngayo, QAPHELA, sikhombe amadiski ngomaka hehehehehehehe, uma enamadiski ayi-10, wazi kanjani ukuthi iyiphi ephukile? hehehehehe, ungavumeli into efanayo yenzeke kimi, ngaphandle kwalokho, uma i-matrix ihlangana, kungaba nzima ukubuyisa idatha kulokhu, yingakho imibuzo ebengiyibuza ngaphambili, uma ufuna ukwenza isipele, yenza i-RAID5, futhi uma ikukhathaza idiski, lapho i-SPARE iqala ukusebenza, inamandla okuvuselela imininingwane elahlekile, wow, mdadm !!! hehehehehe.

Ibukeka kanjani:

mdadm -C /dev/md0 -N RAID0-STRIPE --level=stripe --raid-devices=3 /dev/sdc1 /dev/sdd1 /dev/sdb1 -x /dev/sdv1

Manje ebesingakushiya ukukufometha:

mkfs.ext4 /dev/md0

Silungiselela ifolda ukuhlangana:

mkdir /media/raid

Siyagibela:

mount /dev/md0 /media/raid

Konke sekuhleliwe, manje sibheka isikhala sediski ngomyalo we-df:

Yebo, sesivele silungele ukusetshenziswa kwethu, senza isivivinyo sejubane:

hdparm -t /dev/md0

Hhayi-ke, kubonakala sengathi yayingeyimbi kangako ijijijijijiji

Sesiqedile, manje sengikunikeza ukwazi kwami ​​ukuthi kanjani.

Yini esingayithola kulokhu?

R / Konke ongakucabanga, kusuka ekusetshenzisweni kabusha kwediski kuya kuzipele zedatha, kanye nokuhlanganiswa kokuhlelwa kwezinto abangakwenza, kwi-wiki bachaza izibonelo ezithile ezingaba khona.

Singasebenzisa futhi iSAN encane (Isitoreji Sendawo Yenethiwekhi), ngizochaza kafushane ukuthi lokhu kusebenza kanjani:

• Banama-N PC kanye neseva (konke okune-Debian jijijiji).
• Kulawo ma-PC kufakwe isoftware ukuthi okwenzayo ukuthi lawo ma-PC we-N analawo ma-hard drive atholakala njengengxenye yenethiwekhi.
• Iseva iskena inethiwekhi bese ibathola bonke, ibaphatha sengathi beyingxenye yayo, i-disk yendawo.
• Benza i-matrix ngalawo ma-disc.

Umphumela: I-albhamu ye-SUPER kaN.

Lokhu kubizwa nge-AoE (ATA over Ethernet), ngikushiyela okokufundisa (inamaphutha ayo amancane, mhlawumbe ngizothola okokufundisa kulokhu, okusebenzayo okungu-100%):

namanye amadokhumenti:

Yebo, yilokho kuphela, ngiyethemba kuyakusiza, ngicela, uma ubona noma iliphi iphutha, phawula ukukulungisa futhi unganiki izinkinga kuma-novices.

UKUGONGQWA KUSUKA EKUBA !!!!!!
