The below post explains the step-by-step process to add storage to a mountpoint in ACFS filesystem
1.Before extending the mountpoint storage we need to add an LVM of required Storage Capacity on the server.
For checking the LUN’s available on the server, click here
For now, assume the LUN added is /dev/sdf1
2. As root User, check the available disks by running the below command
$ /usr/sbin/oracleasm listdisks
DATA01
OCR_VOTE01
OCR_VOTE02
OCR_VOTE03
3. Create a new disk using the below command
/usr/sbin/oracleasm createdisk DATA02 /dev/sdf1
Where DATA02 is the name of new disk added
/dev/sdf1 is the LUN added for storage extension.
4. Verify the disk is added by running the below command.
$/etc/init.d/oracleasm listdisks
DATA01
DATA02
OCR_VOTE01
OCR_VOTE02
OCR_VOTE03
5. Navigate to the other cluster nodes and run the scandisks command to reflect the newly added disk on all the nodes of cluster.
$/etc/init.d/oracleasm scandisks
Scanning the system for Oracle ASMLib disks: [ OK ]
$/etc/init.d/oracleasm listdisks
DATA01
DATA02
OCR_VOTE01
OCR_VOTE02
OCR_VOTE03
6. Now login to the database server as GRID user (Where ASM instance is running) to add space to ACFS.
Set the environment as required
export ORACLE_HOME=/u01/app/12.1.0/grid
export PATH=$PATH:$ORACLE_HOME/bin
export ORACLE_SID=+ASM1
$sqlplus / as sysasm
SQL> alter diskgroup DATA add disk ‘/dev/oracleasm/disks/DATA02’;
Diskgroup altered.
7. Increase the space on filesystem
As root user,
$acfsutil size +1G /oradata
acfsutil size: new file system size: 591833071616 (564416MB)

very informative articles or reviews at this time.
I very delighted to find this internet site on bing, just what I was searching for as well saved to fav
For the reason that the admin of this site is working, no uncertainty very quickly it will be renowned, due to its quality contents.
This was beautiful Admin. Thank you for your reflections.
naturally like your web site however you need to take a look at the spelling on several of your posts. A number of them are rife with spelling problems and I find it very bothersome to tell the truth on the other hand I will surely come again again.
This brought real value to my day.
Absolutely loved reading this!
Thanks for making it so relatable.
You’ve explained it perfectly.
