PAS-C01 Operations and Maintenance Practice Question
A company is running SAP ERP on a single EC2 instance with an SAP HANA database. The operations team receives an alert that the /hana/data filesystem is 85% full. The filesystem is mounted from an EBS volume. Which of the following actions should be taken to resolve the issue with MINIMAL downtime?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Increase the size of the existing EBS volume and extend the filesystem.
You can increase the size of an EBS volume and extend the filesystem while the instance is running, without any downtime. The filesystem can be extended online using commands like xfs_growfs for XFS or resize2fs for ext4. Option B is incorrect because adding a new volume and relocating data would require more complex configuration and potential downtime, and it doesn't resolve the issue of the existing filesystem being full. Option C is incorrect because deleting log files is not a sustainable solution and may not free up enough space, and it is not a best practice for production systems. Option D is incorrect because creating a new larger volume and copying data would require the instance to be stopped to swap volumes, causing downtime.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Increase the size of the existing EBS volume and extend the filesystem.
Why this is correct
EBS volumes can be resized online, and the filesystem can be extended without stopping the instance.
- ✗
Add an additional EBS volume and mount it to /hana/data2, then relocate some data.
Why it's wrong here
This would require reconfiguring the database to use the new location, causing complexity and potential downtime.
- ✗
Delete unnecessary log files from the /hana/data directory.
Why it's wrong here
Deleting production data is risky and may not provide enough space; also, the log files are part of the database.
- ✗
Create a new, larger EBS volume, attach it to the instance, and copy the data.
Why it's wrong here
This approach requires stopping the instance or unmounting the volume, causing downtime.
