When I try to stop the acfs I get the following error (all volumes was already disabled with voldisable -G diskgroup_name volume_name)

server03:/>acfsload stop

server03:/>(ucfgacfsctl): ACFS-11038: failed to unconfigure kernel extension oracleacfs.ext, errno 16 (Device busy)
ACFS-9119: oracleacfs.ext driver failed to unload.

When I check processes 'ps -ef | grep acfs' few acfs related processes are seen

server03:/>fuser -f /dev/ofsctl
/dev/ofsctl: 7012562

server03:/>
servers03:/>ps -ef|grep 7012562
oracle 7012562 1 0 Aug 09 - 4:14 asm_acfs_+ASM3

I guess it is holding the acfsload stop... How can I stop this process?

  • So what is the original problem you wanted to solve? ACFS is not a service that needs to be started and stopped. It is a filesystem type used on ADVM volumes in ASM diskgroups. acfsload stop unloads the drivers related to this, which is not possible if something uses them. That process can be stopped by stopping the ASM instance. – Balazs Papp Aug 16 '20 at 22:24
  • I'm having exactly the problem from Doc ID 1599678.1: mount: CLSU-00101: Operating System error message: Function not implemented. The first possible solution from the doc is 1) See if stopping the ACFS/ADVM/OKS modules (As root and from the gi_home/bin, do: acfsload stop) and restarting these (acfsload start), allow the ACFS mount command to complete The second possible solution we don't have the permission at this moment to restart the Oracle Clusterware on each node where the ACFS file system is unable to mount due to this error. – Harry Aug 16 '20 at 22:26
  • The S.O is an IBM AIX on POWER Systems (64-bit) as well – Harry Aug 16 '20 at 22:32

    I do not think you can do that while ASM is online with acfs processes, even if you do not have any volume enabled or filesystem mounted, so I guess you need to wait until you receive permission to do that. – Balazs Papp Aug 17 '20 at 14:12
  • Yes.. After some researches apparently is necessary stop the ASM. Actually it was written in documentation "acfsload: you must dismount Oracle ACFS file systems and shut down Oracle ASM" Thanks for your attention! – Harry Aug 17 '20 at 20:26
