If it's an index then you can just REINDEX. However, you would be
extremely foolish to just reindex and forget the problem. This suggests
strongly that you have hardware problems --- if so, your next problem is
likely to be with an irreplaceable table rather than an easily
rebuildable index :-(. I'd suggest running the usual barrage of
hardware tests: memtest86, badblocks, etc...
