ACFs file system creation, expansion, reduction and other configuration steps

ACFS File system creation configuration

1. 1. Create the mount point directory in the operating system

Such as mount point /oggdata

Both cluster nodes need to be created

[root@syhis1 ~]# mkdir /oggdata

[root@syhis2 datafile]# mkdir /oggdata

[root@syhis1 ~]# /u01/app/grid/cfgtoollogs/asmca/scripts/acfs_script.sh

ACFS file system /oggdata is mounted on nodes syhis1,syhis2

1. 1. ASMCA Configure in the graphical interface

At the node 1 Of grid Under the user , start-up VNC The graphical interface , stay VNC Open in ASMCA Graphical tools （XMANAGER Open up ASMCA Graphics can be ）

1. 1. 1. First of all to root Password configuration

For the later mounting action , Enter... In the drawing root password （ The password is only saved during the graphical interface process , Every time I reopen ASMCA build ACFS You need to re-enter the file system ）

1. 1. 1. Create a volume group

Create volume groups in the graphical interface , Enter the volume group name and size , And create which ASM Disk group is enough .

1. 1. 1. establish ACFS File system mount point

In the graphical interface , Enter the name of the mount point , Such as /oggdata, And assign the user name set to the directory 、 Group permission ;

Select the volume group name created in the previous step , that will do

1. 1. 1. perform ACFS Script

Follow the prompts in the graphics window , Execute the corresponding script .

In execution ASMCA On that mainframe , use ROOT User execution script

[root@syhis1 ~]# /u01/app/grid/cfgtoollogs/asmca/scripts/acfs_script.sh

ACFS file system /oggdata is mounted on nodes syhis1,syhis2

1. 1. 1. View mount point information

[root@syhis1 ~]# df -h

/dev/asm/oggdata-331                300G  1.2G  299G   1% /oggdata

1. 1. ASMCA Medium expansion and shrinkage

adopt ASMCA The graphical interface , Can achieve ACFS Online capacity expansion and space reduction of file system .

During this period, run at ACFS The database in the file system is not affected , It can be used normally. .

1. 1. 1. Space reduction capacity
      2. 

1. 1. 1. Space expands capacity
      2.
