Table 16-89 Options for the acfsutil info fs command

Option	Description
`-o`	Displays the specific file system item from the following list: `freespace` - Amount of free space available in the file system `totalspace` - Size of the file system `mountpoints` - Mount points associated with file systems. `volumes` - Number of volumes associated with the file system `primaryvolume` - Path name of the device associated with file system `available` - Length of time the file system has been available `isadvm` - 1 if an Oracle ADVM volume is present, 0 if not `ismountpoint` - 1 if `path` is the mount point, 0 if `path` is not a mount point `isavailable` - 1 if the file system is available, 0 if file system is not available `iscorrupt` - 1 if the file system is corrupt, 0 if file system is not corrupt `isreplprimary` - 1 if primary file system, 0 if not `isreplstandby` - 1 if standby file system, 0 if not `diskgroup` - Name of the disk group associated with `path` `redundancy` - Type of redundancy used by the Oracle ADVM volume `replication` - 1 if file system has been initialized for replication as the primary or standby file system, 0 if not initialized for replication `resizeincrement` - Allocation unit size in bytes of the Oracle ADVM volume used by `path` `stripewidth` - Stripe width for the Oracle ADVM volume used by `path` `stripecolumns` - Stripe set columns for the Oracle ADVM volume used by `path` `fetasize` - File entry table size which is the amount of storage consumed by the on disk metadata for inodes
`-s` [`interval` [`count`] [`-d]`]	Displays file system statistics. The optional `interval` parameter specifies the amount of time in seconds between each report. The first report contains statistics for the time since the file system mount. Each subsequent report contains statistics collected during the interval since the previous report. The optional `count` parameter can be specified with the `interval` parameter. If the `count` parameter is specified, the value of count determines the number of reports generated at interval seconds apart. If the `interval` parameter is specified without the `count` parameter, the command generates reports continuously until you break out of the command with `Ctrl+c`. The optional `-d` option displays more detailed statistical information.
`-f` [`-v`]	Displays file system fragmentation. The `-v` option displays additional fragmentation information.
`mount_point`	Specifies the directory where the file system is mounted. Not a valid option for replication data.

acfsutil info fs displays information and statistics about Oracle ACFS file systems. If replication has been initiated on a file system, additional flags and status information are displayed. The values for the replication status field are primary, standby, or disabled.

The -o item option displays file system information for the item specified.

The -s option displays the amount and rate of change currently on a file system for the node that the command is run on.

With no option specified, the command displays file system information that includes the volume device name, the size of the file system, the amount of space available on the volume device, the file system mount time on this node, the state of the file system, the user specified block size, the number of Oracle ACFS snapshots, the space consumed by snapshots in the file system, and the optional name or volume label associated with the file system. The possible file system states are displayed in the flags line. These states include:

Offline indicates that the underlying devices are not accessible, possibly due to an Oracle ASM instance failure, disk group forced dismount, or an irrecoverable I/O error. The file system on this node can only be dismounted. All other attempts at access result in errors.
Available indicates that the file system is on line and operational.
Corrupt indicates that the file system should be checked and repaired at the earliest possible convenience to correct a detected inconsistency. For example, run the fsck command on Linux or the acfschkdsk command on Windows to check and repair the file system. Ensure that you run the command in repair mode to correct the problem. For more information, refer to "fsck" and "acfschkdsk".

When viewing space usage values with acfsutil info fs on Windows systems, the values may differ from sizes in Windows folders. The mechanism used by Folder Properties on Windows systems only accounts for files and should be considered an approximate value.

Any user can run acfsutil info fs.
