Troubleshooting not mounting ACFS File System

The ACSF /cloufs was created and registered on the CRS, following node reboot the file system was no longer mounting!

 

I logged on ASMCMD and checked the status of the ASM Volume:

[grid@rednodech07 ~]$ asmcmd
ASMCMD> volinfo -a
Diskgroup Name: FRA

 Volume Name: VOL_CLOUDFS
 Volume Device: ERROR
 State: DISABLED
 Size (MB): 20480
 Resize Unit (MB): 32
 Redundancy: MIRROR
 Stripe Columns: 4
 Stripe Width (K): 128
 Usage: ACFS
 Mountpath: /cloudfs

The output of the command above shows that the volume VOL_CLOUDFS is DISABLED. I tried manually  to restart it, but I got the following error:

ASMCMD> volenable -a
ORA-15032: not all alterations performed
ORA-15477: cannot communicate with the volume driver (DBD ERROR: OCIStmtExecute)
ASMCMD>

 

Then I checked if the ACFS kernel module where loaded into the Linux kernel:

  • oracleacfs (oracleacfs.ko): manages all ACFS filesystem operations.
  •  oracleavdm (oracleavdm.ko): AVDM module enabling direct interface with the filesystem
  • oracleoks (oracleoks.ko): provides memory management, lock and cluster synchronization
[root@rednodech07 ~]# /sbin/lsmod | grep oracle


Because the kernel modules were not loaded, I tried to manally load with the command

/bin/acfsload start

But it didn’t work, so I stopped the Grid Instrastruceure on the local node and I have reinstalled the ACFS drivers:

At this point I have restarted the Grid Infrastructure, the ACFS kernel modules got loaded  and the ASM Volume State become ENABLED.

It remained to restart the ACFS File system with the following command:
