UFS Logging Conventions

• Can UFS logging improve performance?

  UFS logging saves time when you reboot after a failure, because it eliminates the need to run the fsck(1M) command on file systems.

• What are the drawbacks to UFS logging?

  If the log fills up, performance can decrease because the UFS must empty the log before writing new information into it.

• What versions of Solaris work with UFS logging?

  UFS logging can only be used with Solaris 2.4 or later releases.

• Which file systems cannot be logged?

  Non-UFS file systems as well as the root (/) file system cannot be logged.
