Doc Text:
Previously, false alarms for storage capacity based on inodes metrics were raised. This was because the metrics to raise the alerts provided a storage capacity status that could be dynamically changed without any intervention when more storage space was required. When a PVC uses CephFs as storage backend, the inodes metrics such as `kubelet_volume_stats_inodes_free`, `kubelet_volume_stats_inodes`, `kubelet_volume_stats_inodes_used` are not correct because in CephFs inodes get allocated on-demand. By design, CephFS is a filesystem with dynamic inode allocations. With this fix, metrics for `kubelet_volume_stats_inodes_free`, `kubelet_volume_stats_inodes`, and `kubelet_volume_stats_inodes_used` are not provided for CephFS backed PVCs. As a result, false alarms for storage capacity based on inodes metrics are not raised.
