Damaged tables

There are a number of ways you can damage a table.

The following items can damage a table:
  • An incorrect buffer flush
  • A user error
  • Mounting a files system or another chunk on top of a chunk
  • Deleting or updating when the scope of the change is not as narrow as you require

Damaged indexes can cause a table to seem damaged, even though it is not.

The oncheck commands cannot fix most damaged tables. If a page is damaged, oncheck can detect and try to fix the page, but cannot correct the data within the page.
