DETAILS
1) Oracle Automatic Storage Management Cluster File System (Oracle ACFS) is a multi-platform, scalable file system, and storage management technology that extends Oracle Automatic Storage Management (Oracle ASM) functionality to support customer files maintained outside of Oracle Database. Oracle ACFS supports many database and application files, including executables, database trace files, database alert logs, application reports, BFILEs, and configuration files. Other supported files are video, audio, text, images, engineering drawings, and other general-purpose application file data.
2) An Oracle ACFS file system is a layer on Oracle ASM and is configured with Oracle ASM storage. Oracle ACFS leverages Oracle ASM functionality that enables:
- Oracle ACFS dynamic file system resizing.
- Maximized performance through direct access to Oracle ASM disk group storage.
- Balanced distribution of Oracle ACFS across Oracle ASM disk group storage for increased I/O parallelism.
- Data reliability through Oracle ASM mirroring protection mechanisms.
- Oracle ASM is the preferred storage manager for all database files. It has been specifically designed and optimized to provide the best performance for database file types. For a list of file types supported by Oracle ASM.
- Oracle ACFS is the preferred file manager for non-database files. It is optimized for general purpose files.
- Oracle ACFS does not support any file type that can be directly stored in Oracle ASM, except where explicitly noted in the documentation. Not supported means Oracle Support Services does not take calls and development does not fix bugs associated with storing unsupported file types in Oracle ACFS.
- Starting with Oracle Automatic Storage Management 11g Release 2 (11.2.0.3), Oracle ACFS supports RMAN backups (BACKUPSET file type), archive logs (ARCHIVELOG file type), and Data Pump dumpsets (DUMPSET file type). Note that Oracle ACFS snapshots are not supported with these files.
- Oracle ACFS does not support files for the Oracle Grid Infrastructure home.
- Oracle ACFS does not support Oracle Cluster Registry (OCR) and voting files.
- Oracle ACFS functionality requires that the disk group compatibility attributes for ASM and ADVM be set to 11.2 or greater.

Additional Notes
ACFS Additional Notes
Note 1 - ACFS support for new OS updates
ACFS support for new OS updates, service packs, and releases may require
functional changes and therefore ACFS support may not be provided even
though the corresponding Oracle release supports the OS version in question.
For questions regarding OS support not shown above, refer to the corresponding
tracking Enhancement Request:
RHEL8.3: ENH 32408255 - RHEL8.3 SUPPORT FOR ACFS, AFD
Enh 32408303 - SLES15 SP3 SUPPORT FOR ACFS, AFD
Note 2 - ACFS Kernel Support
ACFS kernel support is subject to the OS support life cycle of the underlying OS vendor. Please contact your particular OS vendor for supported releases and kernels.For Oracle Linux, please see:
* https://www.oracle.com/a/ocom/docs/elsp-lifetime-069338.pdf
* http://www.oracle.com/us/support ... policies-069172.pdf
Note 3 - Solaris Support Notes
ACFS is only supported in the Oracle Solaris Global Zones, not in Oracle Solaris Local Zones (formerly known as Solaris Local Containers).
ACFS is supported in Solaris Kernel Zones. (Add: See note 11 for more information).
Note 4 - Linux Support Notes
1) ACFS is supported on Oracle Virtual Machine, both in a Paravirtualized and a Hardware Virtualized guest.
2) ACFS is not supported on any 'debug' kernel variant, such as 'kernel-debug-2.6.18-8.el5.
3) ACFS is supported on PAE kernel variants, such as kernel-2.6.18-8.el5pae.
4) ACFS is only supported on the host machine, not in local containers (LXC).
Note 5 - Installation of 11.2 ACFS on an Unsupported ACFS Platform\Kernel Combination
ACFS is installed as part of the Grid Infrastructure. When the Grid Infrastructure is installed on a platform\kernel combination that ACFS does not support, and support is later applied, post-install steps must be taken in the 11.2 series to ensure the installation is fully-functional. Without these steps, driver auto-load and the ACFS Registry will not work correctly.
Examples:
- Installing 11.2.0.3.0 on Oracle Linux 6 running the RedHat Compatible Kernel, you must take these steps – the base 11.2.0.3.0 ACFS install does not support this variant.
- Installing 11.2.0.2.0 on AIX 7.1 – the base 11.2.0.2.0 ACFS install does not support AIX 7.1.
- Installing 11.2.0.1 or 11.2.0.2 on any UEK kernel.
- Installing 11.2.0.3.0 on UEK 2.6.32-100.
There are 3 options available to enable ACFS functionality in cases like this:
1. Performing ACFS Post-install Steps Manually : This will recreate necessary resources and install drivers after the installation of the base Grid Infrastructure.
2. Performing a Software Only Install : This will patch the Grid Home so that support for ACFS is enabled during the Grid Install, thereby removing the need for additional steps.
3. Rolling Back Your Kernel Update : In the event that the kernel you are running is not supported, but a different kernel on your OS is, this will reenable ACFS functionality.
1) Performing ACFS Post-install Steps Manually:
1-1. After installation of the Grid Home, ensure the appropriate patch or PSU for the ACFS platform support is installed.
1-2. Run “<GridHome>/bin/acfsdriverstate supported” to ensure the patch is correctly installed. The result should be “True”.
1-3. Run “<GridHome>/bin/acfsdriverstate installed” to ensure that ACFS is correctly installed. If the result is “False”, run “<GridHome>/bin/acfsroot install” as root.
1-4. (11.2.0.3) Run “<GridHome>/bin/acfsroot enable” to enable the ACFS resources again.
1-5. (11.2.0.1, 11.2.0.2) Run “<GridHome>/bin/acfsroot reregister” to enable the ACFS resources again.
2) Performing a Software Only Install:
2-1. Begin the install of the Grid Infrastructure.
2-2. Select Software Only Install.
2-3. Apply Patch with ACFS support to Grid Home.
2-4. Continue the install by running the root scripts and the config assistants. For more information, see the Clusterware Install Guide.
3) Enabling ACFS Functionality when a Supported Platform Patch or PSU is Not Available:
3-1. Reboot your machine to a supported kernel, if one exists for the platform that you are trying to install on.
3-2. (11.2.0.3) Run “<GridHome>/bin/acfsroot enable” to enable the ACFS resources again.
3-3. (11.2.0.1, 11.2.0.2) Run “<GridHome>/bin/acfsroot reregister” to enable the ACFS resources again.
Summary: Checking the Functionality of ACFS post-install:
After having executed one of the above options, the following commands can be used to check the ACFS functionality:
a. Run “<GridHome>/bin/acfsdriverstate supported”. The result should be “True”.
b. Run “<GridHome>/bin/acfsdriverstate installed”. The result should be “True”.
c. “<GridHome>/bin/crsctl stat res ora.drivers.acfs -init” should report ONLINE on all nodes.
d. “<GridHome>/bin/crsctl stat res ora.registry.acfs” should report ONLINE on all nodes.
Note 6 - ACFS drivers are not being installed, after applying patch 13146560, without 11.2.0.3.2 installed:
Please follow the steps described in the attached document to implement the solution <click here>.
Note 7 - Opatch (Bug: 16356407) conflict warnings reported during the installation of Patch: 12983005 – UEK 2.6.39 support:
If the Patch: 15876003 (GRID INFRASTRUCTURE PATCH SET UPDATE 11.2.0.3.5) is already installed, then when you try to install the Patch: 12983005 “2.6.39 (UEK) SUPPORT FOR ACFS” on the top, you will receive a patch conflict messages as follows:
ZOP-40: The patch(es) has conflicts with other patches installed in the Oracle Home (or) among themselves.
Following patches have conflicts. Please contact Oracle Support and get the merged patch of the patches : 15876003, 12983005
Solution: You will need to deinstall the Patch: 15876003 (rollback) and then apply Patch: 12983005 “2.6.39 (UEK) SUPPORT FOR ACFS”, which already includes the “GIPSU 11.2.0.3.5”.
Please look at the following document for a complete example:
=)> Note: 1547335.1 Opatch Conflicts Reported During The “Patch 12983005 < 2.6.39 (UEK) SUPPORT FOR ACFS >” Installation (Conflicts Between Patch: 12983005 & Patch: 15876003).
Note 8 - ACFS is certified and supported on both Enterprise and Standard Edition.
Note 9 - Oracle ACFS does not currently have the ability to push database operations directly into storage.
Note 10 - RHEL7 and OL7 support requires 11.2.0.4.4 or later (we do not certify ACFS on top of 11.2.0.[1,2,3] due to dependency on other code in 11.2.0.4.4).
Note 11 - ACFS is supported on Super Cluster Application Domain only (no cell storage) and it requires Engineered Systems GIPSU 12.1.0.2.5 as minimum.
Note 12 - Support for Signed Kernel Drivers:Signed kernel drivers allow the kernel to verify that the code of the driver is unchanged. A signed driver has a public key which the kernel compares to a private key to verify the signatures match.
* Oracle Linux - Linux driver signing is required for "Secure UEFI" boot mode, as well as for UEK4 and later versions of the Linux Kernel. Oracle provides signed drivers for all Oracle Linux versions running both the RedHat Compatible Kernel and the Oracle UEK kernel, beginning with 12.2.0.1, as well as patch sets that have a bug fix for Bug 25098392.
* Red Hat Linux & Suse - driver signing is required for (UEFI) Secure Boot. See MOS note 2416501.1
* Windows - due to a discontinuation in the SHA-1 driver signing algorithm by Oracle, ACFS is not supported on Windows 2008 R1 in 11.2* or 12.*. For other versions of Windows, as per the support Matrix above, Oracle provides signed kernel drivers only for non-Secure Boot implementations.
* Solaris - Oracle provides signed kernel drivers beginning with 12.2.0.1 for all versions of Oracle Solaris.
Note 13 -A UEK patch for UEKR2 and UEKR3 was introduced that increased the kernel stack size. This patch caused panics and instability with Grid Infrastructure Drivers, including ACFS. This was resolved in UEK 2.6.39-400.281.1 and 3.8.13-118.8.1; see UEK Doc ID 2153952.1. Thus, ACFS is not supported with these UEK releases:
- 2.6.39-400.278.1 up to but not including 2.6.39-400.281.1
- 3.8.13-118.5.1 up to but not including 3.8.13-118.8.1
Note 14 - ACFS on AIX requires a user and group management solution that is integrated with IBM RBAC (Role Based Access Control) technology.This includes IBM provided user and group management software such as IBM Directory Server for IBM i (LDAP), but may disallow 3rd party user and group management software.
Please check with your user and group management software provider as to their support for IBM RBAC.
Note 15 - OL7/RHEL7 Update 3 with kernel 3.10.0-514 and later supported with patch 25078431
Note 16 - For installation issues with RHEL7.4 and OL7.4 or later
1) If ACFS and AFD report "Not Supported" after installing a supported release or patches, see Doc ID 2303388.1 for possible kmod issues.
2) In 3.10.0-862 and later Red Hat Enterprise Linux 7 kernels, Red Hat has changed the way that memory is tracked. This can result in panics while unloading a driver that is not created for 3.10.0-862 (Retpoline) and later Red Hat Linux 7 kernel updates. See Bug 29966871.
Note: These panics on unload will not occur if you are already running Retpoline enabled USM drivers which is best practice. However if that is not the case, see below for action required, depending on your scenario.
* If your machine is already running 3.10.0-862 (or later Red Hat Linux 7 kernel):
a) Disable CRS - 'crsctl disable crs'.
b) Reboot
c) Apply the patch for Bug 28069955 - retpoline protection for rh - acfs - usm - spectre (Included in January 2019 RU\PSU).
d) Enable CRS - 'crsctl enable crs'.
* If your machine is not running 3.10.0-862 (or later Red Hat Linux 7 kernel):
a) Apply the patch for Bug 28069955 - retpoline protection for rh - acfs - usm - spectre (Included in January 2019 RU\PSU).
b) Reboot
c) Upgrade Kernel
NOTE - This only affects Red Hat kernels, not UEK kernels.
Note 17 - ACFS support for retpoline compiled kernelsOracle provides enhanced Spectre and Meltdown fix mitigation for ACFS with the following patches. For information on specific backports to your Oracle Grid Infrastructure release, please reference the above tables for your installed version. If a patch is not listed in the above table for your particular release, please reference the base bug to determine if one is available as a BLR. If not, please contact Oracle Support.
1) UEK4 - Bug 27463879 - retpoline support for uek4 - usm - spectre
This support begins with 4.1.12-94.8.2 and later 4.1.12-94 kernels, does not include 4.1.12-103 series, and continues with 4.1.12-112.16.4 and later UEK4 kernels. For more information on specific kernel releases, please see: https://blogs.oracle.com/linux/an-update-on-retpoline-enabled-kernels-for-oracle-linux-v2
Note: You must reboot after installing patch for Bug 27463879 .
2) RedHat 6 and RedHat 7 - Bug 28069955 - retpoline support for rh - acfs - usm - spectre
For RHEL6 retpoline support, use 2.6.32-696.23.1 or later 2.6.32 kernel releases.
For RHEL7 retpoline support, use 3.10.0-862 or later 3.10.0 kernel releases.
Note: You must reboot after installing patch for Bug 28069955.
3) SLES11 and SLES12 - Bug 28142134 - retpoline support for sles - acfs - usm - spectre
For SLES12, use 4.4.120-94.17 or later kernel releases.
For SLES11, use 3.0.101-108.35.1 or later kernel releases.
Note: You must reboot after installing patch for Bug 28142134.
Note that later versions of an OS after the release of these kernels (such as UEK5 or later SLES\RH releases) will carry forward the Spectre retpoline fixes, and thus are not explicitly listed here. Skylake and later CPU architectures may have different fixes for these CVEs, and may not use retpoline.
If a retpoline capable patch is not installed, when ACFS drivers are loaded into a retpoline capable kernel, your kernel will fallback to IBRS protection - this is standard Linux behavior when running non-retpoline compiled drivers or on Skylake CPUs. Depending on your workload, this may cause severe performance issues. To check, run the following command on each node:
dmesg | grep -i -e 'retpoline' -e 'ibrs' -e 'ibpb' -e 'spectre'
A message will be printed for each module: <module>: loading module not compiled with retpoline compiler.
AFD Additional Notes
Note 1 - Stack Size IncreaseA UEK patch for UEKR2 and UEKR3 was introduced that increased the kernel stack size. This patch caused panics and instability with Grid Infrastructure Drivers, including ASMFD and ACFS. This was resolved in UEK 2.6.39-400.281.1 and 3.8.13-118.8.1; see UEK Doc ID 2153952.1. Thus, ASMFD and ACFS is not supported with these UEK releases:
- 2.6.39-400.278.1 up to but not including 2.6.39-400.281.1
- 3.8.13-118.5.1 up to but not including 3.8.13-118.8.1

Note 3 - AFD Thin ProvisioningAFD Thin Provisioning is supported from 2.6.39 and above kernels only.
Note 4 - Propagating ASMFD Updates with 12.1.0.2.X patchingIf ASMFD is configured on the system from 12.1.0.2.X Grid Infrastructure, then the below action is necessary. After an ASMFD one-off patch or ACFSPSU bundle patch is applied, do the following to propagate ASMFD updates into the system (after installing the patch, perform the following actions on each node):
- Bring down the GI stack
- /bin/acfsload stop (as root user)
- /bin/afdroot install (as root user)
- /bin/asmcmd afd_scan (as root user)
- /bin/asmcmd afd_lsdsk (as root user) # already labeled devices should be visible
- /bin/acfsload start (as root user)
- Bring up the GI stack
Note 5 - Checking ASMFD installation correctness- Invoke: /bin/afdroot version_check
- cksum of oracleafd.ko under GIHOME. (<path_from_above_the_command>/oracleafd.ko)
- cksum of oracleafd.ko in the system path. (find /lib/modules -name oracleafd.ko)
- (b) and (c) must be same. If not, latest ASMFD driver was not installed in the system.
- cksum of /lib/libafd*so
- cksum of libafd*so in the system path. (find /opt/oracle -name libafd*so)
- (e) and (f) must be same. If not, latest ASMFD library was not installed in the system.
- NOTE: ER 28476454 is filed to provide a command for ASMFD install correctness check.
