如果使用asmlib，必须使用losetup命令创建块设备，如下：
[root@odb01 ~]# for i in {1..10};do losetup /dev/loop$i /u02/asmdisks/asmdisk$i;done [root@odb01 ~]# ll /dev/loop* brw-rw---- 1 root disk 7, 1 Sep 4 14:35 /dev/loop1 brw-rw---- 1 root disk 7, 10 Sep 4 14:35 /dev/loop10 brw-rw---- 1 root disk 7, 2 Sep 4 14:35 /dev/loop2 brw-rw---- 1 root disk 7, 3 Sep 4 14:35 /dev/loop3 brw-rw---- 1 root disk 7, 4 Sep 4 14:35 /dev/loop4 brw-rw---- 1 root disk 7, 5 Sep 4 14:35 /dev/loop5 brw-rw---- 1 root disk 7, 6 Sep 4 14:35 /dev/loop6 brw-rw---- 1 root disk 7, 7 Sep 4 14:35 /dev/loop7 brw-rw---- 1 root disk 7, 8 Sep 4 14:35 /dev/loop8 brw-rw---- 1 root disk 7, 9 Sep 4 14:35 /dev/loop9 crw-rw---- 1 root disk 10, 237 Sep 4 14:35 /dev/loop-control [root@odb02 ~]# for i in {1..10};do losetup /dev/loop$i /u02/asmdisks/asmdisk$i;done [root@odb02 ~]# ll /dev/loop* 5.4 创建ASM磁盘 [root@odb01 ~]# for i in {1..10};do oracleasm createdisk vol$i /dev/loop$i;done [root@odb02 ~]# oracleasm scandisks Reloading disk partitions: done Cleaning any stale ASM disks...
