innochecksum Error for idbdata

Dear Forum,

is there a way to repair this form of corruption:


[root@hostname idbdata]# innochecksum -p 206334 /var/lib/mysql/idbdata/idbdata01 -v -d
file /var/lib/mysql/idbdata/idbdata01 = 3833593856 bytes (233984 pages)...
checking pages in range 206334 to 206334
page 206334: log sequence number: first = 2722042417; second = 0
page 206334 invalid (fails log sequence number check)

We are using innodb_file_per_table, so there should be no user-data in this page.

Can we avoid doing a full mysqldump, recreate databases and re-import?

Best regards,
Martin
