Recently we wanted to create an ACFS filesystem on a brand new 12.1.0.2 GI installation on Oracle Linux 7.1. According to the documentation<\/a> this should not be an issue as “Oracle Linux 7 with the Unbreakable Enterprise kernel: 3.8.13-33.el7uek.x86_64 or later” is supported.<\/p>\n

\"Read
\nThe “or later” is the important point. In our case:<\/p>\n

\nuname -a\nLinux racp1vm1 3.8.13-55.1.6.el7uek.x86_64 #2 SMP Wed Feb 11 14:18:22 PST 2015 x86_64 x86_64 x86_64 GNU\/Linux<\/pre>\n
 <\/p>\n
Should be fine as this is later than “3.8.13-33.el7uek.x86_64”. So let’s start by creating a diskgroup:<\/p>\n
[grid@racp1vm2 software]$ sqlplus \/ as sysasm\n\nSQL*Plus: Release 12.1.0.2.0 Production on Fri Jul 10 14:37:32 2015\n\nCopyright (c) 1982, 2014, Oracle.

Let’s try again:<\/p>\n
[grid@racp1vm2 software]$ asmcmd volcreate -G DG_ACFS -s 4g vol_acfs\n ORA-15032: not all alterations performed\n ORA-15477: cannot communicate with the volume driver (DBD ERROR: OCIStmtExecute)<\/pre>\n
Hm. Seems something is wrong with the kernel modules:<\/p>\n
\n [grid@racp1vm2 software]$ lsmod | grep -i acfs\n [grid@racp1vm2 software]$<\/pre>\n
We can try to load the drivers manually:<\/p>\n
su - root\n [root@racp1vm2 ~]# export ORACLE_HOME=\/u01\/app\/12.1.0\/grid\n [root@racp1vm2 ~]# cd $ORACLE_HOME\/bin\n [root@racp1vm2 bin]# .\/acfsload start\n ACFS-9459: ADVM\/ACFS is not supported on this OS version: 'unknown'\n [root@racp1vm2 bin]#<\/pre>\n
What? According to the documentation it _is_ supported. Back in 2012 I wrote a small note on that message<\/a> and how one may tweak it. But this is definitely not recommended.<\/p>\n
So what is the cause of this? You can check the available kernel modules for the GI with:<\/p>\n
[root@racp1vm2 grid]# find . -name *.ko ...\n .\/usm\/install\/Novell\/SLES11\/x86_64\/SP2\/3.0.13-0.27\/xen\/bin\/oracleadvm.ko\n .\/usm\/install\/Novell\/SLES11\/x86_64\/SP2\/3.0.13-0.27\/xen\/bin\/oracleacfs.ko\n .\/usm\/install\/Novell\/SLES11\/x86_64\/SP2\/3.0.13-0.27\/xen\/bin\/oracleafd.ko\n .\/usm\/install\/Novell\/SLES11\/x86_64\/SP2\/3.0.13-0.27\/xen\/bin\/oracleoks.ko<\/pre>\n
Nothing about OL7. Hm. Maybe we need to apply a PSU that provides the required modules. I am on the 12.1.0.2 base release:<\/p>\n

Let’s check what the psu provides:<\/p>\n

Looks much better. Once the PSU is applied…:<\/p>\n

… let’s check the kernel modules again:<\/p>\n
[root@racp1vm1 ~]# lsmod | grep -i acfs\n oracleacfs 3335385 0\n oracleoks 499875 2 oracleacfs,oracleadvm\nLooks good, now. Can we create the volume?:\n [grid@racp1vm1 ~]$ asmcmd volcreate -G DG_ACFS -s 4g vol_acfs\n [grid@racp1vm1 ~]$ asmcmd volinfo --all\n Diskgroup Name: DG_ACFS\nVolume Name: VOL_ACFS\n Volume Device: \/dev\/asm\/vol_acfs-288\n State: ENABLED\n Size (MB): 4096\n Resize Unit (MB): 64\n Redundancy: UNPROT\n Stripe Columns: 8\n Stripe Width (K): 1024<\/pre>\n
Perfect. Now the acfs filesystem can be created:<\/p>\n
su -\n [root@racp1vm1 ~]# mkfs.acfs \/dev\/asm\/vol_acfs-288\n mkfs.acfs: version = 12.1.0.2.0\n mkfs.acfs: on-disk version = 39.0\n mkfs.acfs: volume = \/dev\/asm\/vol_acfs-288\n mkfs.acfs: volume size = 4294967296 ( 4.00 GB )\n mkfs.acfs: Format complete.<\/pre>\n
