My host advised updating CentOS 7.4 using ]# yum update to patch security problems from the Meltdown/Spectre microprocessor vulnerabilities. After update my backup service stopped working. Host said edit the /etc/lvm/lvm.conf file and reboot. On reboot the server failed . The host said they needed to comment out all log mounts in /etc/fstab file to boot the server. This worked. However, all my /home/www/[site]/log/ files are gone except error.log. It is 0 bytes. What happened on update and reboot to cause this problem, I need my log files back! Or should I just wait until ISPConfig creates new log files? How can I return /etc/fstab to normal state without commented log files? Will my logs come back? Thanks to anyone for help!
