Oracle ACFS: How to check if ACFS is supported with the kernel currently in use or gather other ACFS driver related information

Description:

You want to check if the ACFS driver can be used with the kernel currently in use. In addition you might want to gather other ACFS driver related information like if it is installed, loaded or which version is used.

 
Commands:

The acfsdriverstate command enables us to gather ACFS driver related information (especially if ACFS is supported with the kernel in use). This binary is part of the Oracle Grid Infrastructure and can be executed as Grid Infrastructure user (e.g. grid) or root.

The following information can be gathered:

  • If ACFS can be used with the kernel currently in use:
    [grid@rac01 bin]$ $ORACLE_HOME/bin/acfsdriverstate -orahome $ORACLE_HOME supported
    ACFS-9200: Supported
    [grid@rac01 bin]$

     

  • If ACFS driver is installed:
    [grid@rac01 bin]$ $ORACLE_HOME/bin/acfsdriverstate -orahome $ORACLE_HOME installed
    ACFS-9203: true
    [grid@rac01 bin]$

     

  • If ACFS driver is loaded:
    [grid@rac01 bin]$ $ORACLE_HOME/bin/acfsdriverstate -orahome $ORACLE_HOME loaded
    ACFS-9204: false
    [grid@rac01 bin]$

     

  • Version of ACFS driver:
    [grid@rac01 bin]$ $ORACLE_HOME/bin/acfsdriverstate -orahome $ORACLE_HOME version
    ACFS-9325:     Driver OS kernel version = 2.6.18-8.el5(x86_64).
    ACFS-9326:     Driver Oracle version = 100804.1.
    [grid@rac01 bin]$
