View Full Version : Mysql_zrm---inappropriate ioctl for device

February 11th, 2020, 08:29 AM

MySQL backup fails with the error "“inappropriate IOCTL for device”.

"/var/local/mysql_binlogs/mysql-bin.003295"Inappropriate IOCTL for device
backup:ERROR: copy-plugin exited with error 256


The above error is just a warning. It can be resolved by adding the warning to tar warnings white-list. This will not affect any of the MySQL-ZRM functionality.

Login to MYSQL-ZRM client server command line.

Add the error text in the tar warning file using below command.

echo "Inappropriate IOCTL for device" >> /usr/share/mysql-zrm/plugins/tar_warnings.txt

Rerun the backup.
