ACFS Administration (Create, Increase, Delete)
For the pre-requisite please refer the below blog post:
1. Verify the ACFS Modules Installed:
lsmod |grep ora
2. Verify the diskgroup ACFS_DG mount on all the RAC cluster nodes
crsctl stat res ora.ACFS_DG.dg -t
3. Create 10G ACFS volume acfs_vol out of 40G ACFS_DG diskgroup
asmcmd -p lsdg ACFS_DG
asmcmd volcreate -G ACFS_DG -s 1G acfs_vol
4. Verify the ACFS volume information
asmcmd volinfo -G ACFS_DG acfs_vol
5. Check acfs volume services at cluster side
crsctl stat res -t | grep -i "advm"
crsctl stat res ora.ACFS_DG.ACFS_VOL.advm -t
6. Create ACFS file system for ACFS devices created by ACFS Volume
mkfs -t acfs /dev/asm/acfs_vol-160
mkdir -p /acfs_test
chown oracle:oinstall /acfs_test_mount_point
7. Register the ACFS device to oracle as a owner
/sbin/acfsutil registry -a /dev/asm/acfs_vol-160 /acfs_test_mount_point -u oracle
crsctl stat res -t | grep -i "acfs_dg"
crsctl stat res ora.acfs_dg.acfs_vol.acfs -t
8. Use srvctl command to mount and unmount ACFS filesystem
srvctl status filesystem -d /dev/asm/acfs_vol-160
srvctl stop filesystem -d /dev/asm/acfs_vol-160
srvctl start filesystem -d /dev/asm/acfs_vol-160
df -h /acfs_test_mount_point
9. Verify the ACFS Volume information again which is mounted on OS filesystem
asmcmd volinfo -G ACFS_DG acfs_vol
10. Verify the configuration of ACFS filesystem
srvctl config filesystem
11. Increase the ACFS Volume and ACFS filesystem by 1G which will make total 11G
acfsutil size +1G –d /dev/asm/acfs_vol-160 /acfs_test_mount_point
asmcmd volinfo -G ACFS_DG acfs_vol
asmcmd -p lsdg ACFS_DG
df -h /acfs_test_mount_point
12. Delete ACFS filesystem and ACFS volume created in case if you are not needed anymore
srvctl stop filesystem -d /dev/asm/acfs_vol-160
/sbin/acfsutil rmfs /dev/asm/acfs_vol-160
asmcmd voldisable -G ACFS_DG acfs_vol
asmcmd voldelete -G ACFS_DG acfs_vol
asmcmd -p lsdg ACFS_DG
crsctl stat res -t | grep -i "acfs_dg"
crsctl stat res ora.acfs_dg.acfs_vol.acfs -t
