ASM: Device is already labeled for ASM disk

当一块磁盘或分区已经被一个DataGroup用过,此时想用这块磁盘或分区重新生成Asmlib生成Oracle磁盘设备时即会报标题的错。

[@more@]

类似如下：

oracle@vvfs$ /etc/init.d/oracleasm createdisk VOL1 /dev/sda1
Marking disk "/dev/sda1" as an ASM disk: asmtool:
Device "/dev/sda1" is already labeled for ASM disk "" [FAILED]

oracle@vvfs$ /etc/init.d/oracleasm deletedisk VOL1
Removing ASM disk "VOL1" [FAILED]

解决问题其实很简单，把磁盘头清一下就可以了：

dd if=/dev/zero of= bs=1024 count=100

现在操作就该正常了：

oracle@vvfs$ dd if=/dev/zero of=/dev/sda1 bs=1024 count=100
100+0 records in
100+0 records out

oracle@vvfs$ /etc/init.d/oracleasm createdisk VOL /dev/sda1
Marking disk "/dev/sda1" as an ASM disk: [ OK ]

oracle@vvfs$
