Question
Does cPanel support the btrfs file system?
Answer
cPanel does not directly support btrfs, it may be possible to use this filesystem. However, you may experience issues with the cPanel software when using this filesystem, such as quotas not working. We have an open feature request for quota support with btrfs:

We recommend using XFS, ext4 or ext file systems on cPanel servers.
