I’m using Amazon Linux EC2 AMI, recently I’m getting this error “barrier-based sync failed” every 10 days.
Running Services
Apache
MySQL
Memcached Server
PHP
This isn’t an error message.
It is an informative log message which indicate that the hardware (or the storage driver) does not support cache flush command. These messages occur normally.
To stop the log message from being logged,
either remount the filesystem using the nobarrier option.
E.g.
mount -o remount,nobarrier /dev/path /path/tomountpointor pass the optionbarrier=offto the kernel on boot.See here and here for more information.
