Kako podesiti RAID 1 (Mirror) na Centosu ? 12.05.2011. u 22:26 · pre 188 meseci #1
Problem je slijedeci: Instalirao sam Elastix (chitaj Centos) na rack server HP proliant koji ima dva fizicka diska od po svaki 500GB.
Prije same instalacije nisam nista podesavao kada je RAID u pitanju. Kako mi centos sada vidi samo jedan disk od 1000GB vjerovatno je RAID 0 (STRIP) po defaultu postavljen ili uopste nije nikako RAID aktiviran. ?

Sve u svemu potrebno je da podesim RAID 1 (dakle mirror mod) , eh sad koji su mi daljni koraci, da li sam trebao prvo podesiti RAID mode pa tek onda instalirati centos ? ili se moze podesiti RAID 1 i nakon instalacije centosa ?? Server ima hardverski kontroler ? Otezavajuca okolnost: Centos je u text modu bez GUI-a.!

Hm, ja sam na HP-ovom Proliantu (ne-rack) prvo podesio RAID 1, pa onda instalirao Linux (OpenSuse).
Imaš tamo kad se pokreće sistem opcije za to, ne znam sad baš napamet, ali nabošćeš.
E, sad, kad je već instaliran, nisam siguran kako i šta :\

Kao sto su ti vec rekli, nista od dodavanja raid-a nakon instalacije,
moraces od nule. Prvo udji u setup raid kontrolera (gledaj prilikom
bootovanja koja kombinacija tastera se pritiska), i tamo napravi raid 1.
Sledeci boot kreni sa CD-a centos instalacije i on ce tada videti samo
jedan disk.

Ajde pretpostavimo da idem iz pocetka (dakle nemam nista instalirano i hocu da prvo podesim RAID 1 ), dakle koji su prvi koraci, vjerovatno mi treba neki RAID tools ?

Prvo ukljucis RAID tj. Smart Array kontroler pa tek onda ulazis u njegov admin alat i kreiras RAID. Na kraju pokreces Centos instalaciju.

HP ProLiant 100 Series servers
To enable the controller and set boot order:
1. Power up the server.
2. When prompted during the start-up sequence, access RBSU by pressing the F10 key.
3. Select Advanced or Advanced Settings.
4. Select SATA Configuration or Hard Drive Configuration.
5. Change SATA #1 to RAID.
6. Return to the previous screen by pressing the Escape key.
7. Select the Boot Menu by pressing the right arrow key.
8. Select Hard Disk Drives.
9. To assign the HP Smart Array B110i SATA RAID Controller as the boot controller, set Ctrl 1 to HP
Smart Array B110i SATA RAID Controller.
10. Press the F10 key to save the setting and to exit RBSU

To create a logical drive using ORCA:
1. Power up the server.
2. When prompted during the start-up sequence, access ORCA by pressing the F8 key.
3. Select Create Logical Drive.
The screen displays a list of all unconfigured physical drives and the valid RAID options for the
system.
4. Use the Arrow keys, Spacebar, and Tab key to navigate around the screen and set up the logical
drive, including an online spare drive, if one is required.

NOTE: You cannot use ORCA to configure one spare drive to be shared among several
arrays. Only ACU enables you to configure shared spare drives.
5. Press the Enter key to accept the settings. Enabling and configuring the controller 7
6. Press the F8 key to confirm the settings and save the new configuration.
After several seconds, the Configuration Saved screen appears.
7. Press the Enter key to continue.
Repeat this procedure to create additional logical drives.

Ukoliko zaista imaš taj model on ima Smart Array B110i koji je SOFTVERSKI RAID (rebrandirani Intel Matrix ICH...R), tako da je po meni bolje koristiti Linux soft RAID. Opet tu je i dmraid:

Ako imaš dodatni HARD RAID osim onog integrisanog onda kako su ti gore kazali...

Citat:
A disk array controller is a device which manages the physical disk drives and presents them to the computer as logical units. It almost always implements hardware RAID


http://en.wikipedia.org/wiki/Disk_array_controller

Ne znam po cemu si zakljucio da je softRAID u pitanju ?

Kolega je u pravu. Ovo je neki FakeRAID :)

Differences between the SATA Smart Array Controller and other Smart Array Controllers:

The B110i doesn't have its own processor !!!! - it feeds off of the server processor
Monitor and Performance Tracking is not supported
No LED Blink support
No Controller Write Cache
Drive LED illumination only on systems with backplane support for drive LEDs

Koristiti ovaj HP-ov raid ili Linux mdadm mu dodje na isto. Samo sto bi i ja pre isao na mdadm da ne komplikujemo zivot.

Zapeo sam na koraku 8. odnosno 9. Naime u BIOSU vidim samo jedan hard disk kada idem na Hard Disk Drives. A pod SATA configuration sam postavio SATA Controller Mode na [RAID]. Tu jos imam SATA Port 1 i do SATA Port 6 i svi su mi [Not Detected]

Kada idem na create a logical drive using ORCA, dobijem poruku "There are no available physical drives".
A pod Available Logical Drives imam Logical drive#1, RAID 0, 1 TB , OK, jel mozda moram prvo obrisati logical drive i onda ici na create i postaviti na RAID 1 ?
