节点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-*
节点2:
lvs能看到asmdata02是存在的,但是lvscan看到状态是inactive的,所以在/dev/mapper/下看不到对应的lv,因此需要激活:
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-*
两个节点:
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 1,4;
节点1:
alter diskgroup DG_PBOSS add disk '/dev/mapper/asm-asmdata02';
