I am trying to backup data on a MySQL Galera node with XtraBackup. Unfortunatelly the tool tells me, that ibdata1 is corrupt. After double checking I indeed found some myisam tables I have importet by error. Droped those and replaced them by innodb tables. However, the error remains (though on a different page now)
xtrabackup version 2.2.12 based on MySQL server 5.6.24 Linux (x86_64) (revision id: 8726828)
xtrabackup: uses posix_fadvise().
xtrabackup: cd to /data/mysql/data
xtrabackup: open files limit requested 0, set to 1024
xtrabackup: using the following InnoDB configuration:
xtrabackup: innodb_data_home_dir = ./
xtrabackup: innodb_data_file_path = ibdata1:12M:autoextend
xtrabackup: innodb_log_group_home_dir = ./
xtrabackup: innodb_log_files_in_group = 2
xtrabackup: innodb_log_file_size = 50331648
>> log scanned up to (22054624442)
xtrabackup: Generating a list of tablespaces
[01] Copying ./ibdata1 to /data/backup/2015-09-02_15-23-50/ibdata1
[01] xtrabackup: Database page corruption detected at page 1320, retrying...
I tripple checked corruption on the database and could not find anyhthing. Is there probably a setup problem with Galera and XtraBackup?
