Isilon: How to Use the TreeDelete job to Delete a Directory

Introduction

TreeDelete is a job option that allows an administrator to delete single or multiple directories from a cluster.

The benefits of TreeDelete are:

• Multi-threaded  - Deletions are done in parallel for better performance.
• Local - The deletion process is local to the cluster. Deletions happen directly from the cluster instead of a client initiating the deletion across the network.
• Logging - Directory deletions are logged to the /var/log/isi_job_d.log.

Procedure

1. Open an SSH connection on any node in the cluster and log in using the "root" account.
2. Run the following command:

# isi job start treedelete --path=<ifs-directory> --priority=<priority> --policy=<policy>

* Where <ifs-directory> is the path to the directory that is to be deleted, <priority> is the priority from 1-10 1 is the highest) 
  and <policy> is the impact level (low, medium, high, off_hours)

# isi job start treedelete --path=/ifs/data/dir_1
# isi job start treedelete --path=/ifs/data/dir_2 --priority=8 --policy=low
