Hi there @oudamsith,

I’ve seen similar problems in the past, one solution worked quite well for me as described here:

• First disable writing barrier for the ext4 fs:

sudo nano /etc/fstab

• Your configuration would look see something like this:

UUID=b87de212-52ca-4600-9e30-6e80e24df1ed / ext4 errors=remount-ro 0 1

• You need to add barrier=0:

UUID=b87de212-52ca-4600-9e30-6e80e24df1ed / ext4 errors=remount-ro,barrier=0 0 1

• Finally you have to reboot your server.

Another thing that you could do is use the MySQLtunner script to test your SQL instance and adjust your settings:
