Frequently Asked Questions
Q: How do I Check Locker Space and File Usage?
A: Linux or OSX Terminal use:
Space: df -h <mount-path> Files: df -h -i <mount-path>
Q: Can Locker be Mounted on All ARC-TS Cluster Compute Nodes?
A: Currently we do not allow Locker to be mounted by very large numbers of clients. This could change in the future so let us know if this would help you. Currently we recommend using Globus to stage data between cluster scratch and Locker between runs. Globus provides a CLI so you can script.
Q: Can I Simultaneously Access Locker from Linux and Windows?
A: Currently Locker supports NFS (Linux) OR CIFS (Windows), Apple OSX supports both. This is known as Multi-Protocol or simultaneous NFS and CIFS access. Because Linux and Windows have different permissions schemes this is complex to manage. We don’t currently support his on Locker but do support it on Turbo. To work around this we recommend using Globus to ease data movement between Locker and systems that cannot mount it natively.
Q: Why can’t we use Locker as general purpose storage?
A: To maintain performance, encryption, professional support, and a low cost, Locker’s design does not make it well suited for general purpose primary storage. For this see the Turbo and MiStorage services.
Q: I deleted data but Locker still reports full?
A: Likely your export has snapshots enabled. Snapshots store changes to Locker exports over time thus deleted data is just ‘moved’ to a snapshot. Eventually snapshots will age out and free space on their own. Snapshot consumption does count against volume space used. To delete or disable snapshots to free space early contact support.
Q: I have free space but Locker reports full?
A: Likely you are at your file quota and are running average file size smaller than 1MByte. This use case is outside the support of Locker’s design and the small files should move to another storage service.
Q: I don’t see my .snapshots folder?
A: Your volume might not have snapshots enabled. If it does it is a hidden file on Linux and OSX terminals use ls -a to view all files including hidden files. To show hidden files in OSX and Windows user interfaces varies by version and can be found in their documentation and online.
Q: My volume shows 2x the size I requested!
A: The system Locker is built on tracks all copies of data in its file system. If a volume requests replication (2 copies of all data) total space will represent the primary and replica copy in total. Thus 1TB of new data will consume 2TB of Locker space.
