Symptoms

The SyncIQ policy fails to start manually. The following error message displays:  

isilon01-2# isi sync jobs start Test_Replication 
An unknown policy error occurred: Check the status of the job on the target cluster and source

Cause

This failure occurs because the isi_migr_sched process is not running on all the nodes.

Resolution

Run the following command to verify that the SyncIQ scheduler is running on all nodes:

# isi_for_array -s 'ps alwx | grep isi_migr_sched'


If it is not running on all nodes, try any of the solutions below: 

  1. Disable then enable the SyncIQ service (isi_migrate):
# isi services -a isi_migrate disable
# isi services -a isi_migrate enable


      2. Start the isi_migr_sched process manually.

# isi_for_array -s '/usr/bin/isi_migr_sched'


      3. Verify that isi_migr_sched is running on all nodes.

# isi_for_array -s ps auwx | grep isi_migr_sched
