6.2.12.1 acfsctl
Control registration for Exascale-managed ACFS file systems.
Purpose
The acfsctl
command controls registration for Exascale-managed implementations of Oracle Advanced
Cluster File System (ACFS).
Syntax
acfsctl register volume-id mount-path [ --attributes attribute=value[,attribute=value] ... ]
acfsctl deregister acfs-id [ --force ]
Command Options
The options for the acfsctl register
command are:
-
volume-id: Identifies the volume that hosts the file system. You can use the
lsacfsfilesystem
command to find the volume identifier associated with each Exascale-managed ACFS file system. -
mount-path: Specifies the file system mount path.
-
--attributes
: Optionally specifies attributes for the file system registration.
The options for the acfsctl deregister
command are:
-
acfs-id: Identifies the ACFS file system being deregistered. You can use the
lsacfsfilesystem
command to find the identifier for each Exascale-managed ACFS file system. -
--force
: Optionally ignores any errors and forces deregistration of the file system, even if it is use.
Usage Notes
Note the following information when using the acfsctl register
command:
-
The specified volume (volume-id) must have an associated EDV attachment and existing ACFS file system, otherwise the command fails.
-
If the EDV attachment is a cluster-wide attachment, the ACFS file system is mounted on every node in the Oracle Grid Infrastructure (GI) cluster. If the EDV attachment is a node-specific attachment, the file system is mounted only on that node. In all cases, the ACFS details are registered with the GI cluster, and the file system is automatically mounted (or remounted) by Oracle Clusterware as required.
Note the following when using the acfsctl deregister
command:
-
If the underlying EDV attachment is a cluster-wide attachment, the ACFS file system is dismounted and the mount point directory is removed on every node in the Oracle Grid Infrastructure (GI) cluster. If the EDV attachment is a node-specific attachment, the file system is dismounted and the mount point directory is removed on that node. The command also removes the ACFS file system registration in the GI cluster.
