SAP S/4HANA Error 14: Insufficient Disk Space
Description
This error indicates that the SAP S/4HANA system or its underlying infrastructure cannot allocate the required disk space for an operation. It typically occurs during data processing, log file generation, or database operations when storage resources are exhausted.
Error Message
ERR_DISK_SPACE_SHORTAGE
Known Causes
3 known causesSystem Disk Full
The primary disk drive hosting SAP S/4HANA data, logs, or operating system files has run out of available space.
Database Log Volume Full
Excessive transaction logging or unmanaged log file growth has consumed all available space on the database log volume.
Temporary File Accumulation
Large amounts of temporary files, generated by applications or the OS, are occupying significant disk space.
Solutions
4 solutions available1. Identify and Purge Old Data in SAP HANA Tables medium
Reduces disk usage by deleting historical or unneeded data from specific HANA tables.
1
Connect to your SAP HANA database using a SQL client (e.g., SAP HANA Studio, hdbsql).
2
Identify tables consuming significant space. You can use the following query to list tables by size:
SELECT * FROM "SYS"."TABLES" ORDER BY "MEMORY_SIZE" DESC;3
Analyze the identified tables for data that can be safely purged. This often includes old application logs, historical transactional data no longer required for reporting or operations, or temporary data.
4
Execute DELETE statements to remove the identified old data. **Caution:** Always back up your data before performing mass deletions and test the delete statements on a non-production system first. Example for deleting records older than a certain date:
DELETE FROM "YOUR_SCHEMA"."YOUR_TABLE" WHERE "TIMESTAMP_COLUMN" < 'YYYY-MM-DD';
-- Commit the transaction if not in auto-commit mode
-- COMMIT;5
After purging, it's recommended to run a RECALCULATE_TABLE_STATS or UPDATE_STATISTICS to reflect the freed space.
CALL "SYS"."RECALCULATE_TABLE_STATS"('YOUR_SCHEMA', 'YOUR_TABLE');2. Clean Up SAP HANA Trace and Log Files easy
Removes temporary trace files, old log files, and core dumps to free up disk space.
1
Access the SAP HANA server's operating system via SSH or RDP.
2
Navigate to the SAP HANA instance's trace directory. This is typically located at `<hanainstance_home>/<sid>/<instance_number>/trace`.
3
Identify and delete old trace files, core dumps, and log files. Be cautious and ensure you are not deleting actively used files. You can use `find` command with time criteria to identify older files.
cd <hanainstance_home>/<sid>/<instance_number>/trace
# Find and delete files older than 7 days
find . -type f -mtime +7 -delete
# Also check for core dumps in the HANA executable directory
cd <hanainstance_home>/<sid>/<instance_number>/exe
find . -name "core*" -delete4
Check the SAP HANA alert files in the `<hanainstance_home>/<sid>/<instance_number>/log` directory and remove old alert files if they are excessively large.
3. Optimize HANA System Configuration and Data Archiving advanced
Adjusting HANA parameters and implementing long-term data archiving strategies.
1
Review SAP HANA memory configuration parameters. Ensure that `global.ini` settings like `shared_memory` and `persistent_memory` are appropriately sized. Incorrect sizing can lead to excessive disk usage for swap or persistence.
2
Implement SAP's standard data archiving solutions (e.g., using SAP Data Archiving Application Administration - SARI transaction) for applications like FI, CO, SD, MM, etc. This moves historical data to archive files on disk or tape, reducing the size of active HANA tables.
3
Consider using SAP HANA Lifecycle Management tools for archiving and managing data. This might involve custom archiving strategies or using tools like SAP Landscape Transformation (SLT) for data replication and archiving.
4
Monitor disk space usage regularly using OS-level tools and SAP HANA monitoring views. Proactive monitoring can prevent the error from occurring in the first place.
df -h4. Increase Disk Space or Move Data to a New Volume medium
A direct solution to add more physical or virtual disk capacity.
1
Identify which specific file systems are full. Use OS commands like `df -h` (Linux) or `Get-PSDrive` (PowerShell) to pinpoint the exact mount points.
df -h2
If using virtual machines or cloud environments, provision additional disk space to the relevant volumes. This might involve resizing existing disks or attaching new ones.
3
If adding new disks, create new file systems and mount them. Ensure these new mount points are added to the `/etc/fstab` (Linux) or equivalent for persistence.
4
For a more involved solution, consider moving large SAP HANA data directories (like the data and log volumes) to a new, larger file system. This requires stopping the SAP HANA database, copying the data, and updating configuration files.
5
After increasing disk space, restart the SAP HANA database services if they were stopped.
