Error message about corrupted mysql.user in DB-Log after Restore of innobackupex bak

Hi all,

i did some tests with recovery of a database out of innobackupex backups.

  • DB: 5.7.13
  • innobackupex version 2.4.3
  • Backup via innobackupex --stream=tar | ssh host “cat - > backup.tar”
  • Restore on other location via tar xvif backup.tar
  • innobackupex --apply-log
  • correcting file ownership and permissions
  • starting restored database

After that I get reproducible the following error message in the db log:

2016-07-22T09:38:03.215194Z 0 [ERROR] /opt/mysql/bin/mysqld: Table ‘./mysql/user’ is marked as crashed and should be repaired
2016-07-22T09:38:03.215396Z 0 [Warning] Checking table: ‘./mysql/user’
2016-07-22T09:38:03.215441Z 0 [ERROR] 1 client is using or hasn’t closed the table properly

Can someone help me as I couldn’t find a hint for a solution?

Best regards
Andreas

Addition: It plays no role whether stored remotely via --stream or locally into filesystem. Same error message on first start.
