+# cephos-set-fill-ratios
+
+## Description
+
+The `cephos-set-fill-ratios` script is used to configure the fill ratios for a Ceph cluster. It sets three important OSD (Object Storage Daemon) ratios that control when Ceph considers a storage device to be near full, backfill full, or completely full.
+
+## Usage
+
+```bash
+cephos-set-fill-ratios -n <ratio> -b <ratio> -f <ratio> [-hv]
+```
+
+## Options
+
+- `-n <ratio>`: Set the nearfull-ratio (default: 0.85)
+- `-b <ratio>`: Set the backfillfull-ratio (default: 0.9)
+- `-f <ratio>`: Set the full-ratio (default: 0.95)
+- `-h`: Show this help message and exit
+- `-v`: Enable verbose mode
+
+## Ratios Explanation
+1. **nearfull-ratio**: When the storage usage reaches this ratio, Ceph will start considering the device as near full. This triggers certain behaviors to prevent the device from becoming completely full. (Default: 0.85)
+1. **backfillfull-ratio**: When the storage usage reaches this ratio, Ceph will consider the device as backfill full. This affects backfill operations where data is being moved to balance the cluster. (Default: 0.9)
+1. **full-ratio**: When the storage usage reaches this ratio, Ceph will consider the device as completely full. No new data will be written to the device until space is freed up. (Default: 0.95)
+
+## Validation
+
+The script validates that the ratios are set in the correct order:
+`nearfull-ratio < backfillfull-ratio < full-ratio`
+
+If the ratios are not in the correct order, the script will display an error and exit.
+
+## Example Usage
+
+```bash
+# Set custom ratios
+cephos-set-fill-ratios -n 0.80 -b 0.85 -f 0.90
+
+# Show help
+cephos-set-fill-ratios -h
+
+# Run with verbose output and set ratios to defaults
+cephos-set-fill-ratios -v
+```
+
+## Default Values
+
+If no options are provided, the script will use the following default values:
+- nearfull-ratio: 0.85
+- backfillfull-ratio: 0.9
+- full-ratio: 0.95
