Procedure to create acfs file system

Pre-checks

1.      The disk space of acfs file system which you want to create will be allocated in asm diskgroup. so please make sure that that much free space is available in the diskgroup.

 Procedure:

Here we are creating a acfs file system of 2gb in +DATA01 diskgroup.

1.      First create a volume of 2GB in +DATA01 diskgroup. 

ASMCMD [+] > volcreate -G DATA01 -s 2G volume01

The volume name is volume01.

2.      Check the details of new created volume. 

ASMCMD [+] > volinfo -G DATA01 volume01

Diskgroup Name: DATA01

         Volume Name: VOLUME01

         Volume Device: /dev/asm/volume01-123

         State: ENABLED

Make a note of volume name and volume device of the new volume. The volume device will be used in the next step.

3.      Create the acfs file system

/sbin/mkfs -t acfs /dev/asm/volume01-123

4.      Register a new volume created for file system in acfs mount registry.

/sbin/acfsutil registry -a  /dev/asm/volume01-123 /acfsmounts/acfs1

Here, /acfsmounts/acfs1 is the directory which the acfs file systems is mounted.

5.      Check if the file system is mounted by acfs mount registry service. If not, then manually mount the file system wrt the new volume device.

/bin/mount -t acfs <volume_device> /acfsmounts/acfs1

                                  

Post Checks

1.  df –hP|grep asm; check that the acfs file system is showing up in df command.

2.      Check the alertlogs of asm for any error.
