V$ASM_FILESYSTEM displays information for every mounted Oracle ACFS.

Column Datatype Description
FS_NAME VARCHAR2(1024) Mount point (primary key)
AVAILABLE_TIME DATE Mount time or the time that the file system became available again; NULL if the file system is not available
BLOCK_SIZE NUMBER File system block size (in kilobytes)
STATE VARCHAR2(13) File system status::
  • NOT AVAILABLE

  • AVAILABLE

  • OFFLINE - Either the Oracle ASM instance is down, the disk group has been forced dismounted, or less commonly, a metadata I/O failure occurred or serious metadata corruption was detected. In the case of a metadata I/O failure, the file system is also marked as corrupt. An offline file system can only be unmounted; other attempts at access result in errors.

TOTAL_SIZE NUMBER Total capacity of the file system (in megabytes)
TOTAL_FREE NUMBER Total free space in the file system (in megabytes)
TOTAL_SNAP_SPACE_USAGE NUMBER Total space used by snapshots (in megabytes)
REPLSTATE VARCHAR2(7) Replication status:
  • NO REPL - Replication is not initialized

  • PRIMARY - File system is initialized for replication as a primary

  • STANDBY - File system is initialized for replication as a standby

CON_ID NUMBER The ID of the container to which the data pertains. Possible values include:
  • 0: This value is used for rows containing data that pertain to the entire CDB. This value is also used for rows in non-CDBs.

  • 1: This value is used for rows containing data that pertain to only the root

  • n: Where n is the applicable container ID for the rows containing data

For this view, the value is always 0.
