Oracle RAC启动CRS-1028，CRS-0223错误

crs_start -all的时候遇到CRS-1028，CRS-0223错误

运行 crs_start -all 的时候，报以下类似错误：

[oracle@rac1 ~]$ crs_start -all

CRS-1028: Dependency analysis failed because of:

'Resource in UNKNOWN state: ora.rac1.ASM1.asm'

CRS-1028: Dependency analysis failed because of:

'Resource in UNKNOWN state: ora.rac2.ASM2.asm'

CRS-0223: Resource 'ora.devdb.devdb1.inst' has placement error.

CRS-0223: Resource 'ora.devdb.devdb2.inst' has placement error.

发现除了ASM和DB外，其它服务都已经起来了，asm是UNKNOWN状态，db有placement error的错误。应当先启动ASM实例，存储才有用，DB对它有依赖性，得后启动。

[oracle@rac1 ~]$ crs_stat ora.rac1.ASM1.asm

NAME=ora.rac1.ASM1.asm

TYPE=application

TARGET=ONLINE

STATE=UNKNOWN on rac1

[oracle@rac1 ~]$ crs_stat ora.rac2.ASM2.asm

NAME=ora.rac2.ASM2.asm

TYPE=application

TARGET=ONLINE

STATE=UNKNOWN on rac2

对于unknown状态的应用，只能是手工先stop再start。

[oracle@rac1 ~]$ crs_stop ora.rac1.ASM1.asm

Attempting to stop `ora.rac1.ASM1.asm` on member `rac1`

Stop of `ora.rac1.ASM1.asm` on member `rac1` succeeded.

CRS-1016: Resources depending on 'ora.rac1.ASM1.asm' are running

CRS-0223: Resource 'ora.rac1.ASM1.asm' has placement error.

[oracle@rac1 ~]$ crs_stop ora.rac2.ASM2.asm

Attempting to stop `ora.rac2.ASM2.asm` on member `rac2`

Stop of `ora.rac2.ASM2.asm` on member `rac2` succeeded.

CRS-1016: Resources depending on 'ora.rac2.ASM2.asm' are running

CRS-0223: Resource 'ora.rac2.ASM2.asm' has placement error.

出现placement error这个问题的原因，主要是资源占用，也就是说两个实例资源出现在同一个节点上，导致另外一个节点得不到需要得资源。

解决办法：出现这个问题，最好是手工用命令启动相关的CRS服务，然后看看具体报什么错误。
启动服务得时候一定要将所有节点服务关闭，然后先启动一个节点，接着观察crs_stat的状态。当这个节点的所有服务正常后，再启动另一个节点。最后通过crs_stat观察全局节点状态。
