Checking a user-defined file system

To check a user-defined file system, perform the following steps.

1. Unmount the user-defined file system being checked.
2. Ensure you have write permission on files in the file system. Otherwise, the fsck cannot repair damaged files even if you answer Yes to repair prompts.
3. Use the smit fsck fast path to access the Verify a File System menu.
4. Do one of the following:
   • Specify the name of an individual file system to check in the NAME of file system field, or
   • Select a general file system type to check, such as a journaled file system (JFS) in the TYPE of file system field.
5. If you want to limit your check to the most likely candidates, specify Yes in the FAST check? field.
   The fast-check option checks only those file systems that are likely to have inconsistencies such as the file systems that were mounted when the system stopped at some point in the past.
6. Specify the name of a temporary file on a file system not being checked in the SCRATCH file field.
7. Start the file system check.
