Disk hardware failure or storage controller error. NFS mount disconnected or timed out during a write. Storage quota exceeded on the underlying volume. EBS or managed disk IOPS limits exceeded on cloud instances

Step 1: Check PostgreSQL logs for the specific file and operation that failed.. Step 2: Verify disk health: `dmesg | grep -i error` on Linux; check cloud storage health dashboard.. Step 3: Check IOPS usage on cloud instances — may need to provision more IOPS.. Step 4: If on NFS, verify the mount is stable and consider moving to local SSD storage.. Step 5: If data files are corrupted, initiate recovery from the latest backup immediately.
