Configure the ACFS Cluster File System on Centos5

After installing an oracle 11.2.0.3 rac test environment on the 64-bit centos5.8 system, it is found that acfs and advm cannot be used, and the acfs and volume tabs on the ASMCA graphic interface are gray! This is because acfs does not support the centos system. The following describes how to use the acfs Cluster File System on centos!

3. Install acfs, configure the acfs and advm modules to start automatic loading, and configure the rac2 nodes in the same way.

4. Add ora. registry. acfs to ocr Configuration

 
 

  
  
[root@rac1 ~]# /u01/app/11.2.0/grid/bin/crsctl add type ora.registry.acfs.type \ 
  
  
> -basetype ora.local_resource.type \

[root@rac1 ~]# /u01/app/11.2.0/grid/bin/crsctl add resource ora.registry.acfs \ 
  
  
> -attr ACL=\'owner:root:rwx,pgrp:oinstall:r-x,other::r--\' \ 
  
  
> -type ora.registry.acfs.type -f 
  
  
 
  
  
[root@rac1 ~]# su - grid -c crs_stat | grep acfs 
  
  
NAME=ora.registry.acfs 
  
  
TYPE=ora.registry.acfs.type 
  
  
 
  
  
[root@rac2 ~]# su - grid -c crs_stat | grep acfs 
  
  
NAME=ora.registry.acfs 
  
  
TYPE=ora.registry.acfs.type 
  
  
[root@rac1 ~]# /sbin/acfsutil registry 
 
 

5. Create and format the volume into an acfs cluster file system and mount it.
