In my experience enabling the finobt (free inode btree) setting made for a better experience under consistent capacity pressure. Context: CentOS 7, 7 TB RAID-10 SSD with ~100million files and ~4% churn rate per day, in production above 80% full for most of 5 years. Twice we experienced an XFS issue but xfs_repair got the FS back online and intact.
