How to gain the space consumed by the deleted files - Isilon

Hello DulaSL,

Here is a link to a Kb that explains how to delete a directory created in Isilon GUI. https://dell.to/4hFsYAP

Have you tried to reboot the node to see if the space has been reclaimed?

Hi @DELL-Sam L​,

Thank you for sharing. Yes, Cluster has been rebooted after the delete execution. The issue is my snapshots are using same partition which I deleted those files.

I have number of snapshots available based on my schedule such as daily,weekly and monthly rotation period. I have deleted one snapshot Since we cannot do modification for the snapshots, but after delete that 35T transfer to the next available snapshot by itself. :( 

Thanks.

Hello DulaSL,

Removing Isilon Snapshots

To remove Isilon snapshots, you can follow these general steps:

1.       Identify Snapshots: Use the command isi snapshot list to view the list of snapshots on the Isilon cluster.

2.       Remove Snapshots: To remove a specific snapshot, you can use the command isi snapshot delete <snapshot_name>.

3.       Automate Snapshot Deletion: You can also set up automated snapshot deletion policies based on retention periods or specific criteria to manage snapshots more efficiently.

Remember that deleting snapshots should be done carefully to avoid data loss or unintended consequences.

Hey @DulaSL 

When you delete files or directories on Isilon, the space is not immediately freed due to snapshots. Since snapshots are present, the deleted data is still retained in the snapshots, preventing the space from being reclaimed.

To free up the space:

1. Delete Snapshots: If the deleted directory is part of a snapshot, you’ll need to delete the snapshot that is consuming the space. You can use the following command:
   
   isi snapshot delete <snapshot_name>
   

2. Check for Snapshot Replication: Ensure there’s no replication keeping the snapshot data alive. You might need to clean up replicated snapshots if applicable.

3. Run Space Reclamation: Once the snapshots are deleted, you may need to run space reclamation to ensure that the free space is available. Use:
   
   isi volume reclaim <volume_name>
   

4. Verify the Space: After deleting snapshots and running the reclamation, check the space again using the isi stats or isi volume stats commands.

This should help reclaim the 35TB of space you’re looking for.
