Небольшая инструкция использования ASM без asmlib

В версии red hat 6.3 не поддерживается asmlib. 

Инструкция сделана на основе документа во вложении Configure RAW on ASM.docx

On first node

1) # fdisk /dev/sdb

Device contains neither a valid DOS partition table, nor Sun, SGI or

OSF disklabel

Building a new DOS disklabel. Changes will remain in memory only,

until you decide to write them. After that, of course, the previous

content won't be recoverable.

Warning: invalid flag 0x0000 of partition table 4 will be corrected

Command (m for help): n

Command action

   e   extended

   p   primary partition (1-4)

p

Partition number (1-4): 1

First cylinder (1-522, default 1):

Using default value 1

Last cylinder or +size or +sizeM or +sizeK (1-522, default 522):

Using default value 522

Command (m for help): w

The partition table has been altered!

Calling ioctl() to re-read partition table.

Syncing disks.

2) # cat /proc/partitions  -- проверяем создание партиции

3) Open /etc/udev/rules.d/60-raw.rules and put these lines there for all disks

ACTION=="add", KERNEL=="sdb1", RUN+="/bin/raw /dev/raw/raw1 %N"

ACTION=="add", KERNEL=="raw*", OWNER=="oracle", GROUP=="oinstall",  MODE=="0660"

3) Run following commands to bound raw disks:

# /bin/raw /dev/raw/raw1 /dev/sdb1

4) Starting udev

# start_udev

ON second node

1) # /sbin/partprobe  --обновляет /proc/partitions

2) Run following commands to bound raw disks:

# /bin/raw /dev/raw/raw1 /dev/sdb1

3) Starting udev

# start_udev

Недостатки:
К сожалению, при такой конфигурации не работает часть функционала ASM, например ACFS:

ASMCMD> volcreate -G data -s 1G  volume_test
ORA-15032: not all alterations performed
ORA-15490: not all instances could add/drop the volume (DBD ERROR: OCIStmtExecute)
