Gitlab backup error: rake aborted Errno::EMFILE: Too many open files

rake aborted Errno::EMFILE: Too many open files

This error happens if the gitlab repositories contains huge number of files.

We can resolve this error by increasing the open files limit.

Step1: Open sysctl conf.

#vi /etc/sysctl.conf

Step2: Add or modify the following line and save the file.

fs.file-max = 2097152

Step3: Reload the configuration.

#sysctl -p

Now the backup will work without any issues.

That's all…
