This article will explain in detail the expansion of udev-based RAC in SUSE. The content of the article is of high quality, so the editor will share it with you for reference. I hope you will have some understanding of the relevant knowledge after reading this article.

Node 1:

Lvcreate-l 100%Free-n asmdata02 asm

Cat / etc/udev/rules.d/99-oraclasm.rules

ENV {DM_NAME} = = "asm-asmdata02", OWNER= "grid", GROUP= "oinstall", MODE= "0660"

/ etc/init.d/boot.udev status

/ etc/init.d/boot.udev restart

Udevadm test / sys/block/dm-4

Ll / dev/dm-*

Node 2:

Lvs can see that asmdata02 exists, but lvscan sees that the state is inactive, so you can't see the corresponding lv under / dev/mapper/, so you need to activate:

Lvchange-ay / dev/asm/asmdata02

Cat / etc/udev/rules.d/99-oraclasm.rules

ENV {DM_NAME} = = "asm-asmdata02", OWNER= "grid", GROUP= "oinstall", MODE= "0660"

/ etc/init.d/boot.udev status

/ etc/init.d/boot.udev restart

Udevadm test / sys/block/dm-4

Ll / dev/dm-*

Two nodes:

Su-grid

Sqlplus / as sysasm

SQL > set lines 150 pages 1000

SQL > col name for A20

SQL > col path for A30

SQL > select group_number,name,path,disk_number,header_status from v$asm_disk order by 1pr 4

Node 1:

Alter diskgroup DG_PBOSS add disk'/ dev/mapper/asm-asmdata02'

So much for the expansion of udev-based RAC in SUSE. I hope the above content can be helpful to you and learn more knowledge. If you think the article is good, you can share it for more people to see.
