[Mediawiki-l] Database error (searchindex corrupted)

[Peter Edwards]

 > './wikidb/searchindex' is marked as crashed and should be repaired

I experienced this same behaviour when upgrading from MySQL 3-4 and from 
MediaWiki 1.6->1.11. I think I've fixed it (hopefully permanently) by 
dumping the table, then dropping it, then re-creating it again. I found 
that repairing the table worked, but the error would re-occur. Hope this 
works for you.
