Managing Oracle ACFS Snapshots

To create and verify a snapshot on node 1:

  1. Create snapshot of the new file system created on node 1.

    For example:

    $ /sbin/acfsutil snap create mysnapshot_20090725 /acfsmounts/acfs1

    See "acfsutil snap create".

  2. Update the test file in the file system so that it is different than the snapshot.

    For example:

    $ echo "Modifying a file in Oracle ACFS File System" > /acfsmounts/acfs1/myfile
  3. List the contents of the test file and the snapshot view of the test file.

    For example:

    $ cat /acfsmounts/acfs1/myfile

$ cat /acfsmounts/acfs1/.ACFS/snaps/mysnapshot_20090725/myfile

    The contents of the test file and snapshot should be different. If node 1 is in a cluster, then you can perform the same list operation on node 2.
