Archive Command Error

Hello team,
I’m trying to run command and getting error ./piwik/piwik_archive_blob_2018_01’ is marked as crashed and last (automatic?) repair failed

I tried to locate to piwik database to try repairing the table (based on other tech article). but I’m not able to see piwik database.

How do I fix this please our visitor tracking and all tracking are lost.

Any help
