Adding Storage Volumes From an Isilon Storage System Gives Permission Denied Error Message in the Wizard or on the CLI

If the UID mapping is set incorrectly or overlooked as part of configuring the Isilon export for use with DataCore vFilO, then the following error will show in the UI:

On the CLI, the following error is shown:

volume-add: Failed to discover volume [172.27.102.190, /ifs/home]: /tmp/1541116442901-0/admin/fYzUcgadEI (Permission denied)

Solution

Go into the Isilon Administration Tool and correctly set the root client UID mapping to admin. It is available under NFS exports settings.

Adding Isilon in the GUI Silently Fails

When trying to add Isilon, a progress bar is briefly shown in the UI that completes however nothing is added to the Storage Systems list. In the Tasks window, under progress, I see “Failed”

Solution

Either the wrong admin credentials or the incorrect SNMP value has been used. Additional details are available on the CLI. Login as the admin user and run

Example: Incorrect SNMP value

I Added a Storage System But I Can’t See My Volume(s)

Verify from the vendor management tools or a regular Linux client that the storage system is exporting the volumes.

I Added a Share/export To My Storage System After I Added It Into DataCore vFilO, How Do I Re-scan It?

A manual rescan is required for DataCore vFilO to detect new exports, shares, volumes or buckets in storage systems. Login into DataCore vFilO using the CLI and execute the following command:

Admin CLI

> node-refresh <-id | -name> --rescan

The output of the command will list all the volumes discovered on the storage system.
