  • Oracle Database Appliance: Resize CloudFS ACFS File System Using ASMCA

    During the Oracle Database Appliance Deployment you can optionally configure CloudFS file system. The default mount point is /cloudfs and set to default size of 50GB. Oracle Database Appliance uses the Oracle Automatic Storage Management Cluster File System (Oracle ACFS) for database and virtual machine files storage. ACFS can only be used to configure shared storage file system on ODA. Oracle ACFS provides both servers with concurrent access to /cloudfs shared file system. The default size of 50GB may not sufficient and must be increased to store big files for business requirement.




    In this article we will demonstrate how to resize the /cloudfs file system using ASMCA GUI interface




    Steps to resize the /cloudfs file system using asmca GUI Interface


    Step 1: Get the current /cloudfs file system size



    Step 2: Start VNC on node 1. Here I am starting VNC as root user. You can choose to start it as Grid or Oracle user.


    [root@odanode1 ~]# rpm -qa *vnc*
    tigervnc-1.1.0-18.el6.x86_64
    tigervnc-server-1.1.0-18.el6.x86_64
    [root@odanode1 ~]# ps -ef|grep vnc
    root     23281 20754  0 13:32 pts/1    00:00:00 grep vnc

    [root@odanode1 ~]# vncserver :1


    You will require a password to access your desktops.


    Password:
    Verify:


    New ‘odanode1:1 (root)’ desktop is odanode1:1


    Creating default startup script /root/.vnc/xstartup
    Starting applications specified in /root/.vnc/xstartup
    Log file is /root/.vnc/odanode1:1.log


    [root@odanode1 ~]# ps -ef|grep vnc
    root     23399     1  1 13:32 pts/1    00:00:00 /usr/bin/Xvnc :1 -desktop odanode1:1 (root) -auth /root/.Xauthority -geometry 1024×768 -rfbwait 30000 -rfbauth /root/.vnc/passwd -rfbport 5901 -fp catalogue:/etc/X11/fontpath.d -pn
    root     23481 23480  0 13:33 pts/1    00:00:00 vncconfig -iconic
    root     23636 20754  0 13:33 pts/1    00:00:00 grep vnc

    Step 3: Start VNC viewer on desktop and enter the hostname/IP address on node 1. Enter the root password as we have started the VNC server using root user.




    Step 4: Switch to grid user and verify the Grid Home



    Step 5: Set Oracle Home to Grid home and start asmca



    Step 6: Click on ASM Cluster File System Tab



    Step 7: Right Click on /cloudfs and select Resize option



    Step 8: Enter the desired new size. Here I am resizing the /cloudfs to 200GB



    Step 9: Resize in progress



    Step 10: Resize completed



    Step 11: Verify the /cloudfs size





    Conclusion


    In this article we have learned how to resize/increase the size of /cloudfs ACFS file system on ODA using ASMCA GUI utility. The cloudfs file system is configured during the ODA deployment and it is set to 50GB which is not sufficient for storing the big files. The cloudfs is build using ACFS and it can be resized easily using ASMCA graphical interface.

  • Oracle Database Appliance: Resize CloudFS ACFS File System Manually

    During Oracle Database Appliance Deployment you can optionally configure CloudFS file system. The default mount point is /cloudfs and set to default size of 50GB. Oracle Database Appliance uses the Oracle Automatic Storage Management Cluster File System (Oracle ACFS) for database and virtual machine files storage. ACFS can only be used to configure shared storage file system on ODA. Oracle ACFS provides both servers with concurrent access to /cloudfs shared file system. The default size of 50GB may not sufficient and must be increased to store big files for business requirement.








    In this article we will demonstrate how to resize the /cloudfs file system manually using ACFS commands.




    Steps to resize the /cloudfs file system




    Step 1: Login to node 1 as grid user the owner of Grid Infrastructure software


    [grid@odanoden1 ~]$ id
    uid=1000(grid) gid=1001(oinstall) groups=1001(oinstall),1003(racoper),1004(asmdba),1005(asmoper),1006(asmadmin)


    Step 2: Verify the existing size of /cloudfs. Here is my case the /cloufs is 200GB and it was resized in the past from 50GB to 200GB


    [grid@odanoden1 ~]$ df -h /cloudfs
    Filesystem           Size  Used Avail Use% Mounted on
    /dev/asm/acfsvol-23  200G  483M  200G   1% /cloudfs


    Step 3: Set the ORACLE SID to +ASM1


    [grid@odanoden1 ~]$ echo $ORACLE_SID


    [grid@odanoden1 ~]$ . oraenv
    ORACLE_SID = [grid] ? +ASM1
    The Oracle base has been set to /u01/app/grid


    [grid@odanoden1 ~]$ echo $ORACLE_SID
    +ASM1


    Step 4: List the ACFS Mounts. Here we can see that /cloudfs volume is /dev/asm/acfsvol-23


    [grid@odanoden1 ~]$ mount |grep asm
    /dev/asm/acfsvol-23 on /cloudfs type acfs (rw)
    /dev/asm/datastore-272 on /u01/app/oracle/oradata/datastore type acfs (rw)
    /dev/asm/datastore-97 on /u02/app/oracle/oradata/datastore type acfs (rw)
    /dev/asm/datastore-23 on /u01/app/oracle/fast_recovery_area/datastore type acfs (rw)


    Step 5: Get the size of the volume /dev/asm/acfsvol-23


    [grid@odanoden1 ~]$ /sbin/advmutil volinfo /dev/asm/acfsvol-23
    Device: /dev/asm/acfsvol-23
    Interface Version: 1
    Size (MB): 204800
    Resize Increment (MB): 64
    Redundancy: high
    Stripe Columns: 8
    Stripe Width (KB): 1024
    Disk Group: RECO
    Volume: ACFSVOL
    Compatible.advm: 12.1.0.2.0


    Step 6: Resize the /cloudfs as follows. Here we are increasing /cloudfs by 50GB


    [grid@odanoden1 ~]$ /sbin/acfsutil size +50g /cloudfs
    acfsutil size: new file system size: 268435456000 (256000MB)


    Step 7: Verify the new size of the volume /dev/asm/acfsvol-23


    [grid@odanoden1 ~]$ /sbin/advmutil volinfo /dev/asm/acfsvol-23
    Device: /dev/asm/acfsvol-23
    Interface Version: 1
    Size (MB): 256000
    Resize Increment (MB): 64
    Redundancy: high
    Stripe Columns: 8
    Stripe Width (KB): 1024
    Disk Group: RECO
    Volume: ACFSVOL
    Compatible.advm: 12.1.0.2.0


    Step 8: Verify the new size of /cloudfs file system


    [grid@odanoden1 ~]$ df -h /cloudfs
    Filesystem           Size  Used Avail Use% Mounted on
    /dev/asm/acfsvol-23  250G  585M  250G   1% /cloudfs

    In this article we have learned how to resize/increase the size of /cloudfs shared file system on ODA.
