I run innochecksum to rewrite the crc32 checksums but it doesn't work.

----

innochecksum --log=/tmp/log.txt ./test.ibd

Fail: page 879 invalid
Exceeded the maximum allowed checksum mismatch count::0

/tmp/log.txt shows:

InnoDB File Checksum Utility.
Filename = ./wp_actionscheduler_actions.ibd
Innochecksum: checking pages in range 0 to 5119
page::0; log sequence number:first = 254643106; second = 254643106
page::0; old style: calculated = 1912029061; recorded = 85334617
page::0; new style: calculated = 644652002; crc32 = 85334617; recorded = 85334617
